For fine grain carbon steels, minimum or maximum levels of grain refiners (Al, Cb, V) can be specified. Boron may be added to killed fine grain carbon steel to improve hardenability.In all carbon steels, small quantities of certain residual elements, such as copper, nickel, molybdenum, chromium, etc., are unavoidably retained from raw materials. Those elements are considered detrimental for special applications, the maximum acceptable content of these incidental elements should be specified by the purchaser.3.2Alloy Steel—Steel is considered to be alloy steel when the maximum of the range given for the content ofalloying elements exceeds one or more of the following limits: manganese, 1.65%; silicon, 0.60%; copper,0.60%; or in which a definite range or definite minimum quantity for any of the following elements is specified orrequired within the limits of the recognized field of constructional alloy steels: aluminum and chromium up to3.99%: cobalt, columbium, molybdenum, nickel, titanium, tungsten, vanadium, zirconium, or any other alloyingelement added to obtain a desired alloying effect.4.Steelmaking Processes—These fall into two general groups: acid or basic, according to the character of thefurnace lining. Thus electric processes may be either acid or basic. Basic oxygen, as the name implies, is an exclusively basic process. The choice of an acid or basic furnace is usually determined mainly by the phosphorus in the available raw materials and the content of phosphorus permissible in the finished steel.Phosphorus is an acid-forming element and, in its oxide form, will react with any suitable base to form a slag in the steelmaking furnace. In basic processes, the metallurgist and steelmaker take advantage of this chemical behavior by oxidizing the phosphorus with iron oxide, which yields up its oxygen to the phosphorus. This permits the iron to remain as part of the steelmaking bath, while the acid phosphoric oxide is separated by floating up into the molten basic lime slag. In acid processes, furnaces are generally lined with silica, which is acid in nature and will not tolerate the use of basic materials for fluxes. Since an acid slag has no affinity for impurities such as phosphorus, the steel cannot be dephosphorized by fluxing and the content of this element remains at the level contained in the raw material, or may be concentrated somewhat in the finished steel due to loss of other materials from the original metallic charge.Most iron ores in the United States are of a phosphorus content suitable only for basic steelmaking processes: hence, all of the nation’s wrought steel is so made. The following are the principal steelmaking processes used in the United States:4.1Basic Electric—The principal advantage of this process is optional control in the furnace permitting steel to betreated under oxidizing, reducing, or neutral slags, and pouring off and replacement of slags during the process. In this manner, and depending on specified requirements, objectionable elements may be substantially reduced and a high degree of refinement obtained in the steel bath. Practically all grades of steel can be made by the basic electric furnace, and the process with or without supplementary processes is used for producing SAE Wrought stainless steels.4.2Basic Oxygen—The prime advantage of this process is the rate at which steel can be produced. The natureof the process is such that large quantities of molten iron must be readily available, since refining is accomplished by the exothermic reactions of high purity oxygen with the various elements contained in the molten iron.4.3Ladle Refining—Today the majority of steels are actually refined to final chemistry and cleanlinessrequirements in a ladle refining facility. This facility takes the ladle of steel which was tapped from the electric arc furnace (EAF) or basic oxygen furnace (BOF), and through the use of the ladle as a vessel further refines the steel. Through the use of optional electric arc reheating capability, inert gas stirring, and optional degassing capabilities; the ladle of steel is trimmed to the final chemistry requirements and inclusions are removed for cleaner steel. The ladle refining station is the facility which actually makes the specific grade of steel to the customer’s specification.4.4Other—Another method increasing in use in the production of stainless, tool, and specialty steels is ESR(electroslag refining). In this process, as-cast electric furnace melted electrodes are progressively melted and solidified in a water cooled copper mold under a blanket of molten flus. Melting results from the heat generated by the resistance of the molten flux to electric current passing between the electrode and the solidifying ingot.Refining occurs as the electrode melts and droplets of molten metal pass through the flux and their impurities are removed by reaction with the flux. The progressively solidified ingot thus produced is very homogeneous and sound, and may be directly processed into mill products.The AOD (argon oxygen decarburization) process has become an important steel refining system for specialty steel grades. Originally employed to replace electric furnace basic slag practice for stainless steels, it is now refining alloy, tool, silicon-iron, electrical, and other specialties. The AOD system refining vessel simply accepts molten iron from whatever source is available, that is, electric furnace, BOF, blast furnace or cupola and completes all chemical and refining stages.The process is based on the principle that when argon gas is mixed with oxygen and injected into the melt, the inert gas dilutes the carbon monoxide resulting from the oxidation of carbon and reduces its partial pressure.This shifts the reaction equilibrium to favor the oxidation of carbon over other oxidizable metals such as chromium. As a result, a higher chromium content can be charged in the melt allowing the conservation of ferrochromium and making this attractive in the economic production of stainless steel.AOD melting also allows control of hydrogen in flake sensitive grades to the point that the need for long anneals is eliminated.4.5Vacuum Treatment—The use of vacuum treatment can be employed with electric furnace, BOF, and ladlemetallurgy furnace steelmaking, and is adaptable to all grades of carbon and alloy steel.There are two types of treatments commonly used. The first is simply “vacuum degassing” the steel to remove hydrogen gas and avoid the necessity for long slow cooling cycles for heavy sections such as blooms, billets, and slabs. The reduced hydrogen content provides steel with improved internal soundness and resistance to internal rupturing or “flaking.” The second treatment is infrequently utilized since the advent of ladle metallurgy facilities. It is referred to as “vacuum carbon deoxidation” (VCD). While this process will also remove hydrogen from the liquid steel, it serves the added purpose of deoxiding the steel. These steels exhibit improved cleanliness compared with conventional product.In today’s modern steelmaking practices, the steel cleanliness is usually achieved in the ladle metallurgy treatment, and VCD treatments are not frequently used. During the ladle metallurgy treatment, the liquid steel is constantly being stirred via argon gas or induction stirring. This induces the liquid steel to have contact with the artificial slag cover on the ladle, the artificial slag captures the inclusions in the steel and prevents them from reentering the molten steel.4.6Strand Casting—This process involves the direct casting of steel from the ladle into slabs, blooms, or billets.In strand casting, a heat of steel is tapped into ladle in the conventional manner. The liquid steel is then teemed into a tundish, which acts as a reservoir to provide for a controlled casting rate. The steel flows from the tundish into the casting machine and rapid solidification begins in the open-ended water cooled copper molds. The partially solidified slab, bloom, or billet is continuously extracted from the mold by an up and down oscillating movement of the mold. Solidification is completed by cooling the moving cast shape through a water cooling spray system. Several strands may be cast simultaneously, depending on the heat size and section size. A reduction in size may be carried out by hot working the product prior to cutting the standard into lengths. Chemical segregation is minimized, due to the rapid solidification rate of the strand cast product.Good casting practice should include measures to protect the molten steel from reoxidation (exposure to air).These measures include, but are not limited to, ladle to tundish shrouding, artificial tundish slag, tundish to mold shrouding, and mold powder. The shrouding technique can employ ceramic shrouds, gaseous shrouds or some combination of both.When two or more heats of steel are cast without interruption, the process is called continuous casting or sequence casting.Some strand casting machines can incorporate electromagnetic stirring (EMS) in the molds and/or below the molds. The EMS stirs the molten steel within the solidified shell. Also below the mold or prior to complete solidification soft or hard reduction of the strand can be employed. These steps help to improve as-cast center quality, reduce segregation, and promote the formation of an equiaxed grain zone.The process of strand casting steel has become the predominant process for the manufacture of steel products. This is due to the advances in the technology of strand casting both from a production aspect and material quality aspect. The quality of strand cast material has become at least equivalent, and in many cases better than the traditional ingot casting process.4.7Ingot Casting—This process has been designed to meet a variety of conditions of manufacture. Ingots areusually cast as square or rectangular in cross section with rounded corners. Occasionally they are cast in round cross sections. They are usually tapered and cast big end up and hot topped. Ingot steel is subject to internal variations in chemical composition and structure due to the natural phenomena which occur as the steel solidifies.Shrinkage in the ingot during solidification results in the formation of a central cavity known as pipe. Primary pipe is located in the upper portion of the ingot. Under some conditions, another shrinkage cavity, known as secondary pipe, may form in the ingot below but not connected with the primary pipe. Secondary pipe is normally not exposed to the air and therefore not oxidized. This allows it to be welded during hot working of the ingot, and results in no detriment to the integrity of the product. Primary pipe is controlled by the hot topping system and any remnants are cropped during the ingot breakdown.There are two methods of ingot production, bottom pouring and top pouring. In bottom pouring, the molten steel flows through a center sprue or trumpet into a runner system filling the ingots from the bottom. Generally there are multiple ingots filled simultaneously from one runner system. The molten steel in the ingot molds is covered by a bottom pouring flux compound.Additionally, the teeming stream can be shrouded to reduce the potential for steel reoxidation and the generation of exogenous inclusions. Once the ingots are filled, a hot topping compound is applied to each ingot.Top pouring is accomplished by filling each ingot individually by teeming the molten steel directly into the top of each ingot much like filling a glass of water. Once the mold is filled, a hot topping compound may be applied to each ingot. Shrouding of the teeming stream is generally more difficult and not as effective in top pouring.5.Steel Processing—After the molten steel has solidified into a solid in either the strand casting process or theingot process the as-cast product is processed into a finished product through several stages. These include primary rolling, inspection, conditioning, hot-rolling, and sometimes cold finishing.5.1Primary Rolling, Inspection, and Conditioning—Cast blooms and ingots are reduced into billets by hot-rolling. This is called primary rolling, and it is also a phase where manufacturers have an opportunity to inspect and enhance the surface of the billet by conditioning.Primary rolling involves the reheating or “soaking” of the ingot or cast bloom followed by the reduction of the heated section by rolling in continuous or reversing type primary mills. In a continuous mill, the section is continuously passed through one or more strands to produce the billet or bloom. In a reversing mill, the section is alternately passed forward and backward, reducing the section into a billet or bloom.Generally, at some point in the primary rolling process, the surface of the section is inspected and conditioned.Inspection is the process of detecting surface imperfections and conditioning is the means of removing them.Inspection of the surface may be visual or automatic by magnetic particle or other means. Conditioning generally involves the removal of surface imperfections by grinding, torching, or other means.Ultrasonic testing of billets can also be performed to test internal quality of the billets.5.2Hot-Rolling—Hot-rolling initially involves the reheating of billets in continuous furnaces that tightly controltemperature and atmosphere to limit surface decarburization. Heated billets exit the furnace and pass througha series of rolling stands for reduction into the bar section, which goes on to a cooling bed or into a coiling tub.Interstand cooling, tension-free rolling and continuous, electronic dimensional measuring with feedback are some of the measures employed to achieve high quality, hot-rolled product.5.3Cold Finishing—Some products receive additional processing through cold finishing operations. Theseoperations are designed to enhance the steel’s surface quality and/or mechanical properties.6.Quality Classifications—Technically, quality, as the term relates to steel products, may be indicative of manyconditions, such as the degree of internal soundness, relative uniformity of composition, relative freedom from detrimental surface imperfections, and finish. Steel quality also relates to general suitability for particular applications. Sheet steel surface requirements may be broadly identified as to the end use by the suffix E for exposed parts requiring a good painted surface, and the suffix U for unexposed parts for which surface finish is less important.Carbon steel may be obtained in a number of fundamental qualities, which reflect various degrees of the quality conditions mentioned. Some of those qualities may be modified by such requirements as austenitic grain size, special discard, macroetch test, special hardenability, maximum incidental alloy elements, restricted chemical composition, and nonmetallic inclusions. In addition, several of the products have special qualities, which are intended for specific end uses or fabricating practices, that is, scrapless nut quality, axle shaft quality, gun barrel quality, or shell quality.Alloy steels also may be obtained in special qualities. Superimposed on some of these qualities may be such requirements as extensometer test, fracture test, impact test, macroetch test, nonmetallic inclusion tests, special hardenability test, and grain size test.For complete descriptions of the qualities and supplementary requirements for carbon and alloy steels, reference should be made to the latest applicable Steel Products Manual Section. Titles of these manuals are listed in Section 2.7.Types of Steel—In steelmaking, the principal reaction is the combination of carbon and oxygen to form a gas.If the oxygen available for this reaction is not removed prior to or during casting, the gaseous products continue to evolve during solidification. Proper control of the evolution of gas determines the type of steel produced. All alloy steels and strand cast steels are killed steels. Killed steels refers to those steels which have a deoxidizing element (such as aluminum or silicon) added to eliminate the gaseous oxygen. Carbon steel may be produced as killed, semi-killed, or rimmed. The vast majority of steels are of the killed type.7.1Killed steel is a type of steel from which there may be only a slight evolution of gases during solidification of themetal. Killed steels have more uniform chemical composition and properties than the other types. However, there may be variations in composition, depending on the steelmaking practices used. Alloy steels are of the killed type, while carbon steels may be killed or may be of the following types:7.2Rimmed steels have marked differences in chemical composition across the section. The typical structure ofrimmed steel results from a marked gas evolution during solidification of the outer rim, caused by a reaction between the carbon in the solidifying metal and dissolved oxygen. The outer rim is lower in carbon, phosphorus, and sulfur than the average composition, whereas the inner portion, or core, is higher than the average in those elements. The technology of manufacturing rimmed steels limits the maximum contents of carbon and manganese and those maximum contents vary among producers. Rimmed steels do not retain any significant percentages of highly oxidizible elements, such as aluminum, silicon, or titanium.Rimmed steel products, because of their chemical composition and their surface and other characteristics, may be used advantageously for the manufacture of finished articles involving cold bending, cold forming, deep drawing, and in some cases, cold heading applications.7.3Semi-killed steels have characteristics intermediate between those of killed and rimmed steels. During thesolidification of semikilled steel, some gas is evolved and entrapped within the body of the ingot. This tends to compensate for the shrinkage that accompanies solidification.7.4Capped steels have characteristics, which combine some features of rimmed and semi-killed steels. Afterpouring, the rimming action is stopped after a brief interval by means of mechanical or chemical capping. The thin lower carbon rim has surface and forming properties comparable to those of rimmed steel, whereas the uniformity of composition and properties more nearly approaches that of semi-killed steels. Capped steel products, because of their chemical composition, surface, and other characteristics, may be used to advantage when the material is to withstand cold bending, cold forming, or cold heading.monly Specified Elements—It is the purpose here to outline briefly the effects of various elements onthe steelmaking practices and steel characteristics. The effects of a single element on either practice or characteristics are modified by the influence of other elements. These interrelations, frequently of a synergistic nature, must be considered when evaluating a change in specified composition. However, to simplify this presentation, the various elements will be discussed individually. The scope of this discussion will permit only suggestions of the modifying effects of other elements or of steelmaking practices on the effects of the element under consideration. Aluminum, titanium, and columbium, though not specified in SAE standard steels, are at times present to achieve deoxidation or fine grain size.8.1Carbon is present in all steel and is the principal hardening element. The hot-rolled strength and hardnessincrease significantly with increased carbon content, particularly at the low and medium carbon levels. Ductility and weldability decrease with increasing carbon content. Carbon also determines the level of hardness or strength attainable by quenching. Carbon segregates, and because of its major effect on properties, carbon segregation is frequently of more significance and importance than the segregation of other elements.8.2Manganese contributes to strength and hardness, but to a lesser degree than carbon. The amount of increasein these properties is dependent upon the carbon content, that is, higher carbon steels are affected more by manganese than lower carbon steels. Increasing the manganese content decreases weldability, but to a lesser extent than carbon. Manganese tends to increase the rate of carbon penetration during carburizing and enhances hardenability in quenching. Manganese is generally beneficial to surface quality, particularly in resulfurized steels. Manganese has a moderate tendency to segregate during solidification.8.3Phosphorus in appreciable amounts increases the hot-rolled strength and hardness, but at the sacrifice ofductility and toughness. Increased phosphorus content in quenched and tempered steels is also detrimental to ductility, toughness, and fatigue. Consequently, for most applications, phosphorus is maintained below a specific maximum. This varies with the grade and quality level. In certain low carbon, free machining steels, higher phosphorus content is specified for its effect on machinability. Phosphorus has a pronounced tendency to segregate.8.4Sulfur lowers ductility and toughness in the transverse direction as the content increases. Weldabilitydecreases with increasing sulfur. Sulfur is very detrimental to surface quality, particularly in the lower manganese steels. For these reasons, a maximum sulfur content is specified for most steels. However, for some steels, sulfur is added to improve the machinability. Sulfur also has a pronounced tendency to segregate. Sulfur occurs in steel primarily in the form of manganese sulfide inclusions. Obviously, greater frequency of such inclusions is to be expected in the resulfurized grades.8.5Silicon is one of the principal deoxidizers used in steelmaking and, therefore, the amount of silicon present isrelated to the type of steel. Rimmed and capped steels contain no significant amounts of silicon. Semi-killed steels may contain moderate amounts of silicon, although there is a definite maximum amount that can be tolerated in such steels. Killed carbon steels may contain any amount of silicon up to 0.60% maximum.Silicon is somewhat less effective than manganese in increasing as-rolled strength and hardness. Silicon has only a slight tendency to segregate. In low-carbon steels, silicon is usually detrimental to surface quality, and this condition is more pronounced in low-carbon resulfurized grades.Silicon can help improve toughness and reduce relaxator in heat-treated spring steels.8.6Copper has a moderate tendency to segregate. Copper in appreciable amounts is detrimental to hot workingoperations. Copper adversely affects forge welding, but it does not seriously affect arc or acetylene welding.Copper is detrimental to surface quality and exaggerates the surface defects inherent in resulfurized steels.Copper is, however, beneficial to atmospheric corrosion resistance when present in amounts exceeding 0.20%.8.7Lead is an element sometimes added to carbon and alloy steels through mechanical dispersion duringteeming or casting for the purpose of improving the machining characteristics of such steels. When so added, the range is generally 0.15 to 0.35%.8.8Boron is added to steel in small amounts (0.0005 to 0.0030%) to increase hardenability. Special melting andheating techniques are essential to obtain the desired hardenability results. Boron does not measurably affect the hot-rolled, normalized, or annealed properties of steel. Boron is most effective as a hardenability agent in lower carbon steels.8.9Chromium is generally added to steel to increase resistance to corrosion and oxidation, increasehardenability, improve high temperature strength, or improve abrasion resistance in high-carbon compositions.Chromium is a strong carbide former. Complex chromium-iron carbides go into solution in austenite slowly;therefore, a sufficient heating time before quenching is necessary.Chromium is essentially a hardening element and is frequently used with a toughening element such as nickel to produce superior mechanical properties. At higher temperatures, chromium contributes increased strength, but is ordinarily used for applications of this nature in conjunction with molybdenum.8.10Nickel, when used as an alloying element, is a ferrite strengthener. Since nickel does not form any carbidecompounds in steel, it remains in solution in the ferrite, thus strengthening and toughening the ferrite phase.Nickel steels are easily heat treated because nickel lowers the critical cooling rate. In combination with chromium, nickel produces alloy steels with greater hardenability, higher impact strength, and greater fatigue resistance than are possible with carbon steels.8.11Molybdenum promotes hardenability of steel and is useful where hardenability control is essential. Whenmolybdenum is in solid solution in austenite prior to quenching, the reaction rates for transformation become considerably slower as compared with carbon steel. It widens the temperature range of effective heat treated response since it has a tendency to form stable carbides. Molybdenum provides hardenability with a minimum detrimental effect on cold-forming characteristics. Molybdenum steels in the quenched condition require higher tempering temperatures to obtain the same degree of softness as comparable carbon and alloy steels.It also increases the tensile and creep strengths of steel at high temperatures. Alloy steels that contain 0.15% to 0.30% molybdenum show a minimized susceptibility to temper embrittlement.8.12Vanadium increases the hot-rolled mechanical properties of steel and may be used to enhance hardenability.It can be used to inhibit austenitic grain growth through the formation of precipitates. The grain growth inhibiting effects promote a fine grain structure that imparts strength and toughness to steels. However, the precipitates of Al, Cb, and/or Ti offer a more effective means of austenitic grain coarsening resistance.Vanadium is also used in some microalloy steel since its ability to produce vanadium carbonitride precipitates from hot forging or hot-rolling temperatures imparts strength and hardness levels comparable to quench and tempered steels. It can be used in combination with columbium, aluminum, and/or titanium.8.13Aluminum is primarily used as a deoxidizer and austenitic grain refiner. In increased amounts, it combinesreadily with nitrogen to form aluminum nitrides which combines readily with nitrogen to form aluminum nitrides which contribute to high surface hardness and superior wear resistance.8.14Selenium is added to enhance machinability. It combines with manganese sulfide inclusions to modify theirshape to be more globular; it also combines with manganese to form manganese selenides, which are inclusions which behave like manganese sulfides and are beneficial to machining.8.15Tellurium is added to enhance machinability. Its main purpose is to modify the shape of the manganesesulfides. However, tellurium will form iron tellurides, which result in hot shortness problems and require special hot-rolling considerations.8.16Bismuth is added to enhance machinability. It behaves much like lead in that it is present in a finely dispersedform in the solid steel.8.17Calcium is added to steel to promote the strand castability of aluminum grain refined steel. It forms calciumaluminate inclusions which remain liquid at steel casting temperatures, as opposed to alumina inclusions which are solid at casting temperatures. The alumina inclusions build up on nozzles and shrouds and cause clogging problems. Calcium is also added to strand cast or ingot steels to modify the alumina inclusions from a hard, brittle stringer to a softer, globular inclusion which is less detrimental to carbide tooling during machining operations.。

The hardness criterion is 50 HRC normally, but see Table 1 under 5.1.Effective case depth should always be determined on the part itself, or on samples or specimens having a heat-treated condition representative of the part under consideration.3.2Total Case Depth—The distance (measured perpendicularly) from the surface of the hardened or unhardenedcase to a point where differences in chemical or physical properties of the case and core no longer can be distinguished.4.Chemical Methods4.1General—This method is generally applicable only to carburized cases, but may be used for cyanided orcarbonitrided cases. The procedure consists in determining the carbon content (and nitrogen when applicable) at various depths below the surface of a test specimen. This method is considered the most accurate for measuring total case depth on carburized cases.4.2Procedure for Carburized Cases—Test specimens shall normally be of the same grade of steel as partsbeing carburized. Test specimens may be actual parts, rings, or bars and should be straight or otherwise suitable for accurate machining of surface layers into chips for subsequent carbon analysis.Test specimens shall be carburized with parts or in a manner representative of the procedure to be used for parts in question. Care should be exercised to avoid distortion and decarburization in cooling test specimens after carburizing. In cases where parts and test specimens are quenched after carburizing, such specimens should be tempered at approximately 600 to 650 °C (1100 to 1200 °F) and straightened to 0.04 mm (0.0015 in) max total indicator reading (TIR) before machining is attempted. The time at temperature should be minimized to avoid excessive carbon diffusion.Test specimens must have clean surfaces and shall be machined dry in increments of predetermined depth.The analysis of machined chips will then accurately reveal the depth of carbon penetration. Chosen increments usually vary between 0.05 and 0.25 mm (0.002 and 0.010 in) depending upon the accuracy desired and expected depth of case.Chips from each increment shall be kept separate and analyzed individually for carbon content by an accepted method. Total case depth is considered to be the distance from the surface equivalent to the depth of the last increment of machining whose chips analyze to a carbon content 0.04% higher than that of the established carbon content of the core.Specialized electron microprobe analyses on carefully prepared cross-sections represent an alternate procedure with potentially greater accuracy and speed, and is recommended when equipment is available. 5.Mechanical Methods5.1General—This method is considered to be one of the most useful and accurate of the case depth measuringmethods. It can be effectively used on all types of hardened cases, and is the preferred method for determination of effective case depth. The use of this method requires the obtaining and recording of hardness values at known intervals through the case. For determination of effective case depth, the 50 HRC criterion is generally used. The sample or part is considered to be through hardened when the hardness level does not drop below the effective case depth hardness value. In some instances involving flame and induction hardened cases, it is desirable to use a lower hardness criterion. Suggested hardness levels are tabulated in Table 1 for various nominal carbon levels.A plot of hardness versus depth from the surface will facilitate this reading. Figures 1, 2, 3, and 4 illustrate the recommended procedures.Hardness testers which produce small, shallow impressions should be used for all of the following procedures,in order that the hardness values obtained will be representative of the surface or area being tested. Those testers which are used to produce Diamond Pyramid or Knoop Hardness Numbers are recommended,although testers using heavier loads, such as the Rockwell superficial, A or C scales, can be used in some instances on flame and induction hardened cases.Considerable care should be exercised during preparation of samples for case depth determination by any of the mechanical methods, to insure against grinding or cutting burn. The use of an etchant for burn detection is recommended as a general precaution, because of the serious error which can be introduced by its presence.FIGURE 1—SPECIMEN FOR TAPER GRIND PROCEDUREFIGURE 2—SPECIMEN FOR CROSS SECTION PROCEDUREFIGURE 3—SPECIMEN FOR ALTERNATE CROSS SECTION PROCEDUREFIGURE 4—SPECIMEN FOR STEP GRIND PROCEDURETABLE 1—CARBON CONTENTCarbon ContentEffective Case Depth Hardness 0.28–0.32% C35 HRC 0.33–0.42% C40 HRC 0.43–0.52% C45 HRC 0.53% and over 50 HRC5.2Hardness Traverse Procedure—Cut specimens perpendicular to hardened surface at critical location beingcareful to avoid any cutting or grinding practice which would affect the original hardness.Grind and polish specimen. Surface finish of the area to be traversed shall be polished finely enough so the hardness impressions are unaffected—that is, the lighter the indentor load, the finer the polish necessary.The procedure illustrated by Figure 2 is recommended for the measurement of light and medium cases. The alternate procedure illustrated in Figure 3 is recommended for medium and heavier cases.The hardness traverse should be started far enough below the surface to ensure proper support from the metal between the center of the impression and the surface. Subsequent impressions are spaced far enough apart so as not to distort hardness values. The distance from the surface of the case to the center of the impression is measured on a calibrated optical instrument, micrometer stage, or other suitable means.5.3Taper Grind Procedure—This procedure, illustrated by Figure 1, is recommended for measurement of lightand medium cases.A shallow taper is ground through the case, and hardness measurements are made along the surface thusprepared. The angle is chosen so that readings, spaced equal distances apart, will represent the hardness at the desired increments below the surface of the case.Unless special anvils are used, a parallel section should be prepared so that readings are taken at right angles to the surface. Care should be exercised in grinding to prevent tempering or rehardening.5.4Step Grind Procedure—This procedure illustrated by Figure 4 is recommended for measurement of mediumand heavy cases.It is essentially the same as the taper grind section method with the exception that hardness readings are made on steps which are known distances below the surface.A variation in this procedure is the step grind method where two predetermined depths are ground to insurethat the effective case depth is within specified limits.6.Visual Methods6.1General—This method employs any visual procedure with or without the aid of magnification for reading thedepth of case produced by any of the various processes. Samples may be prepared by combinations of fracturing, cutting, grinding, and polishing methods. Etching with a suitable reagent is normally required to produce a contrast between the case and core. Nital (concentrated nitric acid in alcohol) of various strengths is frequently used for this purpose.6.2Macroscopic—Magnification methods for determination of case depth measurement are recommended forroutine process control, primarily because of the short time required for determinations, and the minimum of specialized equipment and trained personnel needed. They have the added advantage of being applicable to the measurement of all types of cases. However, the accuracy can be improved by correlation with other methods more in keeping with engineering specifications for the parts being processed. These methods are applied normally to hardened specimens, and while a variety of etchants may be employed with equal success, the following procedures are typical and widely used.6.2.1F RACTURE—Prepare product or sample by fracturing. Examine at a magnification not to exceed20diameters with no further preparation.6.2.2F RACTURE AND E TCH—Water quench product or samples directly from the carburizing temperature. Fractureand etch in 20% nitric acid in water for a time established to develop maximum contrast. Rinse in water and read while wet.6.2.3F RACTURE OR C UT, AND R OUGH G RIND—Prepare specimen by either fracturing, or cutting and rough grinding.Etch in 10% nital for a period of time established to provide a sharp line of demarcation between case and core. Examine at magnification not to exceed 20 diameters (Brinell glass) and read all the darkened area for approximate total case depth.6.2.4F RACTURE OR C UT, AND P OLISH OR G RIND—Prepare specimen by fracturing or cutting. Polish or grindthrough No. 000 or finer metallographic emery paper or both. Etch in 5% nital for approximately 1 min.Rinse in two clean alcohol or water rinses. Examine at magnification not to exceed 20 diameters (Brinell glass) and read all of the darkened zone. After correlation, effective case depth can be determined by reading from external surface of specimen to a selected line of the darkened zone.6.3Microscopic—Microscopic methods are generally for laboratory determination and require a completemetallographic polish and an etch suitable for the material and the process. The examination is made most commonly at 100 diameters.6.3.1C ARBURIZED C ASES—The microscopic method may be used for laboratory determinations of total case andeffective case depths in the hardened condition. When the specimen is annealed properly, the total case depth and the depth of the various zones—hypereutectoid, eutectoid, and hypoeutectoid—also can be determined quite precisely.1a.Hardened Condition1.Fracture or cut specimen at right angles to the surface.2.Prepare specimen for microscope and etch in 2 to 5% nital (concentrated nitric acid in alcohol).3.For effective case depth, read from surface to metallographic structures which have been shown tobe equivalent to 50 HRC.4.For total case depth, read to the line of demarcation between the case and core. In alloy steelsquenched from a high temperature, the line of demarcation is not sharp. Read all the darkened zonethat indicates a difference in carbon from the uniform core structure.b.Annealed Condition1.For specimens previously hardened or not cooled under controlled conditions.2.The specimen to be annealed may be protected by copper plate or any suitable means forpreventing loss of carbon.3.Pack in a small, thin-wall container with a suitable material such as charcoal.4.Place container in furnace at 40 to 80 °C (75 to 150 °F) above the upper critical temperature (Ac3)for the core. (Generally an annealing temperature of 870 to 925 °C (1600 to 1700 °F) is satisfactory.)5.Leave in furnace long enough for specimen to reach furnace temperature, but not for an excessivetime at temperature, as carbon diffusion will increase total case depth.c.Cooling Rates1.Carbon Steels—A satisfactory cooling rate is obtained by cooling the container in mica, lime, or otherinsulating material at a rate which will reduce the temperature to 430 °C (800 °F) in 2-1/2 to 3 h.Cool as desired below 430 °C (800 °F).1.For certain applications involving moderate to high hardenability alloy steels in the 0.4 to 0.8% carbon range, the M s method of case depthdetermination to specific carbon level has been found to be effective. In this method, the specimen is austenitized at the time and temperature sufficient to more than take into solution the alloy and carbon at the desired level of measurement. It is then quenched into salt at the M s tem-perature of the carbon level desired, held just long enough to temper the martensite at all lower carbon levels and water quenched. Subse-quent polishing and etching disclose a sharp line of demarcation between tempered and untempered martensite, which can be read with a Brinell glass to a precision of 0.05 mm (0.002 in). Additional information on this technique can be obtained by reference to "The Application of M s Points to Case Depth Measurement," by E. S. Rowland and S. R. Lyle, ASM Transactions, Vol. 37 (1946) pp. 26–47.2.Alloy Steels—Slower cooling rates or isothermal transformations are required. If martensite isretained in the structure, better contrast after etching may be obtained by tempering the specimensat 540 to 600 °C (1000 to 1100 °F). Cool as desired after tempering.3.Section, prepare, and etch specimen as desired under 6.3.1, (a) Hardened Condition. Etching timeis usually longer.4.For total case depth measurement, read the depth of carbon enrichment.5.For specimens cooled slowly after carburizing. If the production carburizing cycle provides theproper cooling rate, or the cooling rate is otherwise controlled as described for the annealedcondition, specimens may be prepared and examined without reheating after carburizing. This isoften possible when the parts are cooled in solid compound when the boxes are not too small.6.3.2C ARBONITRIDED C ASES—Carbonitrided cases are measured for total case depth in the hardened condition.High quenching temperatures, high alloy content of the steel, and high carbon content of the core decrease the accuracy of readings obtained by this method.a.Section, prepare, etch, and read as described in 6.3.1, (a) Hardened Condition.6.3.3C YANIDED C ASES—Cyanided cases are thin, and only the microscopic method is recommended for accuratecase depth measurements. The usual cyanide case contains a light etching layer followed by a totally martensitic constituent, which in turn is followed by martensite with increasing networks of other constituents, depending on the type of steel which has been cyanided. Cyanided cases are read in the hardened condition only and results reported as total case depth.a.Section, prepare, and etch specimen as described in 6.3.1, (a) Hardened Condition.b.Read to the line of demarcation between the case and core.c.(When a sharp line of demarcation does not exist, the use of a hardness test such as described underMechanical Methods is recommended.)6.3.4N ITRIDED C ASES—The microscopic method is used chiefly in those situations where the available samplecannot readily be prepared for the more desirable hardness traverse method. It may be difficult to read the case depth because the nitride network gradually diminishes.a.Section and prepare the specimen as described in Carburized Cases, (a) Hardened Condition.b.Etch in 10% nital.c.Read all darkened zone for total case depth.6.3.5F LAME OR I NDUCTION H ARDENED C ASES—Since no chemical change occurs in flame or induction hardening,readings must be made in the hardened or hardened and tempered condition only. A procedure for reading effective case depth may be established by correlating microstructures with a hardness traverse method. A minimum hardness of 50 HRC is used commonly but some other point may be selected or required, for example, in lower carbon steels that do not reach 50 HRC when fully hardened. See Table 1. The microstructure at the selected location will differ depending on steel composition, prior treatment (annealed, heat treated, or other treatments) and on the hardness level chosen.a.Section, prepare, and etch specimen as described in 6.3.1, (a) Hardened Condition.b.For total case depth, read the entire zone containing structures hardened by the process.c.For effective case depth, read to selected microstructure correlated with specified hardness. PREPARED BY THE SAE IRON AND STEEL TECHNICAL COMMITTEE DIVISION 3—TEST PROCEDURESRationale—This Document has not changed other than to put it into the new SAE Technical Standards Board Format. References were added as Section 2. Definitions changed to Section 3. All other section numbers have changed.Relationship of SAE Standard to ISO Standard—Not applicable.Application—Case hardening may be defined as a process for hardening a ferrous material in such a manner that the surface layer, known as the case, is substantially harder than the remaining material, known as the core. The process embraces carburizing, nitriding, carbonitriding, cyaniding, induction and flame hardening. In every instance, chemical composition, mechanical properties, or both are affected by such practice.This testing procedure describes various methods for measuring the depth to which change has been made in either chemical composition or mechanical properties. Each procedure has its own area of application established through proved practice, and no single method is advocated for all purposes.Methods employed for determining the depth of case are either chemical, mechanical, or visual, and the specimens or parts may be subjected to the described test either in the soft or hardened condition. The measured case depth may then be reported as either effective or total case depth on hardened specimens, and as total case depth on unhardened specimens.It should be recognized that the relationship between case depths as determined by the different methods can vary extensively. Factors affecting this relationship include case characteristics, parent steel composition, quenching conditions, and others. It is not possible to predict, in some instances for example, effective case depth by chemical or visual means. It is important, therefore, that the method of case depth determination be carefully selected on the basis of specific requirements, consistent with economy.Reference Section"The Application of M s Points to Case Depth Measurement," by E.

These fittings are intended for general application in hydraulic systems on industrial equipment and commercial products.These fittings are capable of providing leakproof, full flow connections in hydraulic systems operating at working pressures as specified in Table 1 for respective sections.Since many factors influence the pressure at which a hydraulic system will or will not perform satisfactorily, the values shown in SAE J1065 should not be construed as a guaranteed minimum.For any application, it is recommended that sufficient testing be conducted and reviewed by both the user and fitting manufacturer to assure that performance levels will be safe and satisfactory.The standard is divided into six sections as follows:Section 1—37 Degree Flare Tube Fittings Section 2—Flareless Tube FittingsSection 3—O-ring Plugs (for O-ring Ports see SAE J1926)Section 4—Hydraulic Pipe Fittings (formerly SAE J926)Section 5—Adapter Unions (formerly in SAE J516)Section 6—Tables for Calculating Dimensions on Special Sizes2.References2.1Applicable Publications.

Details of contour shall be optional with manufacturer provided the tabulated dimensions aremaintained and serviceability of the fittings is not impaired.3.6Straight Threads. Unified Standard Class 2A external and Class 2B internal threads with modified minordiameters, where specified, shall apply to plain finish (unplated) fittings of all types. For externally threaded parts with additive finish, the maximum diameters of Class 2A may be exceeded by the amount of the allowance, that is, the basic diameters (Class 2A maximum diameters plus the allowance) apply to an externally threaded part after plating. For internally threaded parts with additive finish, the Class 2B diameters and modified minor diameters apply after plating.The pitch diameter tolerance shall be the same as the corresponding diameter-pitch combination and class of the Unified fine and 12 thread series. See SAE J475 (ISO R725).Where external threads are produced by roll threading and body is not undercut, the unthreaded portion of body adjacent to the shoulder may be reduced to the minimum pitch diameter.External threads shall be chamfered and internal threads shall be countersunk as specified in the dimensional tables.3.7Thread Eccentricity Tolerances. The various thread elements of Class 2A external and Class 2B, modified,internal threads on tube fittings shall be concentric within the following limitations:3.7.1E XTERNAL T HREAD (S CREW)a.Where screw pitch diameter is maximum and screw major diameter is maximum, these two threadelements must be concentric. However, if the screw major diameter is out-of-round, undersize, thesetwo thread elements may be eccentric at the point of out-of-roundness, a full indicator reading amountequal to the screw major diameter tolerance.b.Where screw pitch diameter is minimum and screw major diameter is maximum, these two threadelements may be eccentric a full indicator reading amount equal to the screw pitch diameter tolerance.c.Where screw pitch diameter is maximum and screw major diameter is minimum, these two threadelements may be eccentric a full indicator reading amount equal to the screw major diameter tolerance.d.Where screw pitch diameter is minimum and screw major diameter is minimum, these two threadelements may be eccentric a full indicator reading amount equal to the sum of the screw pitch diametertolerance and the screw major diameter tolerance.3.7.2I NTERNAL T HREAD (N UT)a.Where nut pitch diameter is minimum and nut minor diameter is minimum, these two thread elementsmust be concentric.

The external surfaces and threads of all carbon steel parts shall be plated or coated with a suitablematerial that passes a 72 h salt spray test in accordance with ASTM B 117. Any appearance of red rust during the 72 h salt spray test shall be considered failure, except for the following:a.All internal fluid passages.b.Edges such as hex points, serrations, and crests of threads where there may be mechanicaldeformation of the plating or coating typical of mass-produced parts or shipping effects.c.Areas where there is mechanical deformation of the plating or coating caused by crimping, flaring,bending, and other post-plate metal forming operations.d.Areas where the parts are suspended or affixed in the test chamber where condensate canaccumulate.NOTE—Cadmium plating is not preferred due to environmental reasons. Parts manufactured to this document after January 1, 1997, shall not be cadmium plated. Internal fluid passages shall beprotected from corrosion during storage. Changes in plating may affect assembly torques andrequire requalification, when applicable.3.11Workmanship. Workmanship shall conform to the best commercial practice to produce high-quality fittings.Fittings shall be free from all hanging burrs, loose scale, and slivers which might become dislodged in usage and all other defects which might affect their serviceability. All sealing surfaces must be smooth except that annular tool marks up to 2.5 µm (100 µin) max A.A. shall be permissible.3.12Assembly Considerations. Use of a compatible lubricant is desirable in assembling dryseal pipe threads onhydraulic tube or pipe fittings to minimize galling and effect a pressure-tight seal.The O-ring washer must be clinched to fitting with a tight slip fit to an interference fit. The slip fit shall be tight enough so that washer cannot be shaken loose to cause it to drop from its uppermost position by its own weight. The interference fit shall not require a locknut torque more than that indicated in Table 3 of SAE J1453.Position the washer farthest from the end of the fittings as shown in Figure 10A. Care must be taken not to clinch washer on the transition area between diameter Y and locknut thread which results in a loose washer when it is repositioned at assembly. Washer flatness allowance is given in Table 3 of SAE J1453. Any surface out of flatness must be uniform (not wavy) and concave with respect to the O-ring boss end of the fitting.Torque values listed in Table 2A are for controlled testing to establish compliance to the performance requirements set forth in T able 1. Recommended assembly torques by manufacturers may vary from T able 2A.Smaller sizes (–2 through –8) of 37 degree flare fittings are less tolerant to over torquing than the larger sizes.Over torquing in these sizes causes deformation of 37 degree cone of the male end. Excessive deformation of the cone results in loss of clamping force and, hence, loss of seal. It also reduces flow area.Plating combination, surface finish, lubrication, etc., influence fittings’ propensity for deformation when assembled to a given torque value. For this reason, many manufacturers recommend assembly to a given number of turns or flats of nut from finger tight position. This method circumvents the influence of variables listed previously, eliminating possibility of excess deformation of 37 degree cone. It is recommended that this method be followed wherever possible.4.Performance Requirements. See Appendix B for minimum number of samples required for testing.4.1Working Pressure (For All Sections). Working pressures for fittings shall be as listed in Table 1 or asspecified in respective section. Proof pressures shall be twice the working pressures, and minimum burst pressures shall be four times the working pressures.4.2Proof Test (For All Sections). All fittings for tubing and adapters shall be capable of withstanding proofpressure for a period of 1 min without failure or leakage.4.3Burst Test (For All Sections). Burst test shall be conducted at minimum torque values or minimum number ofturns from finger tight position specified in assembly procedure by manufacturer. For testing only, all adapter to hose fittings or tube fitting threads and contact surfaces shall be lubricated with SAE 10W hydraulic oil prior to assembly. Test blocks for burst testing shall be hardened to 45 to 55 HRC and left unplated. Adjustable fittings shall be backed out one full turn from finger tight position. The test shall be conducted as specified in SAE J343.4.4Cyclic Endurance (Impulse) Test (For All Sections). All tube fittings and adapters shall pass a cyclicendurance test for one million cycles at 133% of corresponding working pressures as established per 4.1. The cycle test shall be conducted at minimum torque or number of turns from finger tight assembly. For testing only, all threads and contact surfaces shall be lubricated with SAE 10W hydraulic oil prior to assembly. Cycle rate shall be uniform at –5 to 1.3 Hz and shall conform in magnitude and frequency to the wave pattern shown in Figure 1 of SAE J343.4.5Hose Coupling Interface. Along with over torque test per 4.7, adapter interface and nut portion of hose stemassemblies shall meet proof, burst, and cyclic endurance requirements of hose to which they are attached. 4.6O-ring. The standard O-ring used on SAE straight thread end for testing shall be nitrile (NBR) rubber with adurometer “A” hardness of 90.4.7Over Torque Test (For Fittings in Section 1). Fitting swivel nuts shall be capable of withstanding theovertorque qualification test with no indication of failure. For testing only, all threads and contact surfaces shall be lubricated with SAE 10W hydraulic oil prior to applying torque listed in respective sections. T est adapters for torque testing shall be hardened to 40 to 50 HRC and left unplated. The fitting shall be restrained during test and the wrench shall be located at the threaded end of the nut hex. Nuts that go through brazing in production shall be put through similar annealing cycle before testing.Definition of failure after torque testing:a.Nut cannot be removed by hand after breakaway.b.Nut cannot swivel freely by hand.c.Any visible cracks or severe deformation that would render nut unuseable.4.8Repeated Assembly (For Fittings in Section 1). Three samples each of male flare shaped fittingsassembled to tube flare (with sleeve and nut) and female swivel end shall be tested. Samples shall be assembled and disassembled ten times. Fittings shall be tightened, with threads lubricated with 10W hydraulic oil, to maximum torque values shown in Table 2A. Proof test per 4.2 shall be conducted following the first, fifth, and tenth assembly. There shall be no leakage and the fitting nut shall remain free to swivel by hand after the tenth disassembly.TABLE 2A—QUALIFICATION TEST TORQUE (b) REQUIREMENTS5.Section 1—37 Degree Flare Tube Fittings. The 37 degree flared tube fittings shall be as shown in Figures 1to 15 and Tables 3 to 7. Since the basic design of these fittings is derived from Air Force and Navy Standards for 37 degree flared fittings which meet a performance specification, any future changes should not be detrimental to the design or performance. Dimensions for double and single 37 degree flares on tubing to be used with these fittings are given in Figure 3 and Table 2 of SAE J533.Nom SAE Dash Size Nom Tube OD mm Nom Tube OD in Tube End and SAE O-Ring Port Thr’d Size 37 degree Flare End Swivel Nut Torque Nm 37 degree Flare End Swivel Nut Torque lb-ft 37 degree Flare End Swivel Nut Over TorqueNm37 degree Flare End Swivel Nut Over Torquelb-ftSAE O-Ring (a)Port End Torque Nm SAE O-Ring (a)Port End Torque lb-ft 2 3.180.125 5/16-24 8- 9 6- 7 15 11 8- 9 6- 7 3 4.760.188 3/8 -24 11- 12 8- 9 19 14 11- 12 8- 9 4 6.350.250 7/16-20 15- 16 11- 12 24 18 18- 20 13- 15 5 7.940.313 1/2 -20 19- 21 14- 15 31 23 23- 26 17- 19 6 9.520.375 9/16-18 24- 28 18- 20 42 31 29- 33 22- 24 812.700.500 3/4 -16 49- 53 36- 39 80 59 49- 53 40- 431015.880.625 7/8 -14 77- 85 57- 63114 85 59- 64 43- 481219.050.7501-1/16-12107-119 79- 88160118 93-102 68- 751422.220.8751-3/16-12127-140 94-103186138122-134 90- 991625.40 1.0001-5/16-12147-154108-113214158151-166112-1232031.75 1.2501-5/8 -12172-181127-133271200198-218146-1612438.10 1.5001-7/8 -12215-226158-167339250209-231154-1703250.802.0002-1/2 -12332-350245-258497368296-325218-240(a) This torque is applicable to fittings in Sections 1, 2, 3, and 5.(b)Test torques given here are for low carbon steel fittings only.
