Salt baths shall be tested in accordance with AMS2759.Coatings3.3.4 ProtectiveA supplemental coating or plating is permitted, when approved by the cognizant engineering organization. Fine grain copper plating in accordance with AMS2418 or nickel plating in accordance with AMS2424 may be used without approval but the surface contamination specimens in 3.6.1 shall not be plated (See 8.3).3.4 Procedure3.4.1 PreheatingPreheating until furnace stabilization in the 900 to 1200 °F (482 to 649 °C) range is recommended before heating parts above 1300 °F (704 °C) if the parts have previously been heat treated to a hardness greater than 35 HRC, have abrupt changes of section thickness, have sharp reentrant angles, have finished machined surfaces, have been welded, have been cold formed or straightened, have holes, or have sharp or only slightly-rounded notches or corners.3.4.2 SoakingHeating shall be controlled, as described in AMS2759, such that either the heating medium or the part temperature, as applicable, is maintained at the set temperature in Table 2 or 3 for the soak time specified herein. Soaking shall commence when all control, indicating, and recording thermocouples reach the specified set temperature or, if load thermocouples as defined in AMS2759 are used, when the part temperature reaches the minimum of the furnace uniformity tolerance at the set temperature.3.4.2.1 Parts coated with copper plate or similar reflective coatings that tend to reflect radiant heat shall have their soaktime increased by at least 50%, unless load thermocouples are used.3.4.3 AnnealingShall be accomplished by heating to the temperature specified in Table 2, soaking for the time specified in Table 4, and cooling to below the temperature specified in Table 2 at the rate shown in Table 2 followed by air cooling to ambient temperature. Isothermal annealing treatments may be used providing equivalent hardness and microstructure are obtained. Isothermal annealing shall be accomplished by heating to the annealing temperature specified in Table 2, soaking for the time specified in Table 4, cooling to a temperature below the critical, holding for sufficient time to complete transformation, and air cooling to ambient temperature.Annealing3.4.4 SubcriticalShall be accomplished prior to hardening by heating in the range 1150 to 1250 °F (621 to 677 °C), soaking for the time specified in Table 4, and cooling to ambient temperature. Steel parts of the 9Ni - 4Co types shall be subcritical annealed as specified in Table 2.3.4.5 Pre-Hardening Stress RelievingShall be accomplished prior to hardening by heating in the range 1000 to 1250 °F (538 to 677 °C), soaking for not less than the time specified in Table 4, and cooling to ambient temperature.3.4.6 NormalizingShall be accomplished by heating to the temperature specified in Table 2, soaking for the time specified in Table 4, and cooling in air or atmosphere to ambient temperature. Circulating air or atmosphere is recommended for thicknesses greater than 3 inches (76.2 mm). Normalizing may be followed by tempering or subcritical annealing.3.4.7 Hardening (Austenitizing and Quenching)All parts, except those made from H-11, 52100, or M-50 steels, shall be in one of the following conditions prior to austenitizing: normalized, normalized and tempered, normalized and overaged, or hardened. If such parts have been normalized only, without tempering or overaging, they shall be preheated within the range of 850 to 1250 °F (454 to 677 °C) before exposure to the austenitizing temperature (See Table 2 Note 2). Welded parts and brazed parts with a brazing temperature above the normalizing temperature shall be normalized before hardening. Welded parts should be preheated in accordance with 3.4.1. Hardening shall be accomplished by heating to the austenitizing temperature specified in Table 2, soaking for the time specified in Table 4, and quenching as specified in Table 2. The parts shall be cooled to or below the quenchant temperature before tempering.3.4.8 Tempering or AgingShall be accomplished by heating quenched parts to the temperature required to produce the specified properties. Parts should be tempered within 2 hours of quenching (See 3.4.8.1). Tempering for specific tensile strengths for each alloy is shown in Table 3. Soaking time shall be not less than 2 hours plus 1 hour additional for each inch (25 mm) of thickness or fraction thereof greater than 1 inch (25 mm). Thickness is defined in AMS2759. When load thermocouples are used, the soaking time shall be not less than 2 hours. Multiple tempering is permitted. When multiple tempering is used, parts shall be cooled to ambient temperature between tempering treatments.3.4.8.1 Prior to final tempering parts may be snap tempered for 2 hours at a temperature, usually 400 °F (204 °C), thatis lower than the final tempering temperature (See 8.5.1).3.4.9 StraighteningWhen approved by the cognizant engineering organization, straightening shall be accomplished at either ambient temperature, during tempering, or by heating to not higher than 50 °F (28 °C) below the tempering temperature. Ambient temperature straightening or hot or warm straightening after tempering shall be followed by stress relieving. It is permissible to retemper at a temperature not higher than the last tempering temperature after straightening during tempering.3.4.10 Post-Tempering Stress RelievingWhen required by the cognizant engineering organization, parts shall, after operations which follow hardening and tempering, be stress relieved by heating the parts to 50 °F (28 °C) below the tempering temperature and soaking for not less than 1 hour plus 1 hour additional for each inch (25 mm) of thickness or fraction thereof greater than 1 inch (25 mm). When load thermocouples are used, the soaking time shall be not less than 1 hour. Stress relief is prohibited on parts that have been peened or thread- or fillet-rolled after hardening and tempering.3.5 PropertiesParts shall conform to the hardness specified by the cognizant engineering organization or to the hardness converted from the required tensile strength in accordance with AMS2759.3.5.1 SurfaceContaminationSalt baths and the protective atmosphere in furnaces for heating parts above 1250 °F (677 °C), when less than 0.020 inch (0.51 mm) of metal is to be removed from any surface, shall be controlled to prevent carburization or nitriding and to prevent complete decarburization (See 3.5.1.1). Partial decarburization shall not exceed 0.006 inch (0.15 mm) and a severity of 5 points HRC converted from Knoop. Depth and severity are described in ARP1820. Intergranular attack shall not exceed 0.0007 inch (0.018 mm). Rejection criterion for total depth of decarburization shall be the microhardness reading that has more than a 20-point Knoop, or equivalent, decrease in hardness from the core hardness. Rejection criterion for severity of decarburization is the difference between the HRC hardness (converted from Knoop) at 0.0003 inch (0.008 mm) and that of the core. Rejection criterion for carburization and nitriding shall be that the microhardness shall not exceed the core hardness by 20 points Knoop or more, or equivalent, at a depth of 0.0003 inch (0.008 mm). Tests shall be in accordance with 3.6.1. The requirements of this paragraph also apply to the cumulative effects of operations such as normalizing followed by austenitizing or austenitizing followed by reaustenitizing (See 3.5.1.4). For reheat treatments, the original specimen or a portion thereof shall accompany the parts and be tested after the reheat treatment.3.5.1.1 Unless specifically informed that at least 0.020 inch (0.51 mm) will be removed from all surfaces of parts, theheat treating processor shall heat treat the parts as if less than 0.020 inch (0.51 mm) will be removed from some surfaces and, therefore, shall heat treat using controlled atmosphere which will produce parts conforming to surface contamination requirements.3.5.1.2 Parts that will be machined after heat treatment, but which will have less than 0.020 inch (0.51 mm) of metalremoved from any machined surface may be reclassified as Type 1, as described in 3.3.1, and need not meet the requirements of 3.5.1 as heat treated, when it is demonstrated by tests (See 3.6.1.1) on each load that all surface contamination exceeding the requirements of 3.5.1 is removable from all machined surfaces, taking into account distortion after heat treatment.3.5.1.3 Furnaces used exclusively to heat treat parts that will have all contamination removed shall not require testing.3.5.1.4 The heat treating processor shall be responsible for determining whether cumulative heat treating operations atthat facility, as described in 3.5.1, have caused excessive surface contamination.3.6 Test MethodsShall be in accordance with AMS2759 and as follows:Contamination3.6.1 SurfaceTesting shall be performed by the microhardness method in accordance with ASTM E 384, supplemented, if necessary, by ARP1820. Test specimens shall be of the same alloy as the parts. Unless otherwise specified, test specimens shall be in the as-quenched condition except that secondary hardening steels, such as H-11, shall be tempered. In addition, the presence of total depth of decarburization, carburization, and nitriding shall be determined by etching with the appropriate etchant and examining at approximately 250X magnification. The depth of intergranular attack shall be determined on an unetched specimen at approximately 250X magnification (See 8.4).3.6.1.1 Testing for reclassification in 3.5.1.2 may be by any microhardness method if more than 0.002 inch (0.05 mm)is subsequently machined off all machined surfaces.4. QUALITY ASSURANCE PROVISIONSThe responsibility for inspection, classification of tests, sampling, approval, entries, records, and reports shall be in accordance with AMS2759 and as specified in 4.1 and 4.2. 4.1Classification of TestsThe classification of acceptance, periodic, and preproduction tests shall be as specified in AMS2759 and as specified in 4.1.1 and 4.1.2.4.1.1 Acceptance TestsIn addition to the tests specified in AMS2759, tests for surface contamination (3.5.1) shall be performed on each lot. Alternatively, if carbon potential is controlled automatically and either indicated or recorded, frequency of surface contamination tests may be in accordance with the sampling plan of 4.2. 4.1.2 Preproduction TestsIn addition to the tests specified in AMS2759, tests for surface contamination (3.5.1) shall be performed prior to any production heat treating on each furnace, each kind of atmosphere to be used in each furnace, and for each Class B atmosphere at two carbon potentials, up to 0.40% and over 0.40%. 4.2Alternative Sampling Plan4.2.1 An alternative test plan to meet the requirements of 4.1.1 is permitted for heat treatment processes verified bystatistical process control (SPC) to be stable and capable. 4.2.1.1 A process is considered stable when statistical evaluation of the product and process parameters show that allmeasured values fall within established control limits. 4.2.1.2 A process is considered capable when, after achieving and maintaining stability, all parts running to the processhave a minimum C pk of 1.33 with a confidence level of 90%. NOTE: C pk is defined as the smaller of either C pl or C pu as determined by Equation 1 or Equation 2:σ−=3LSLX C pl (Eq. 1) σ−=3XUSL C pu (Eq. 2) where:X = process averageLSL = lower specification limit* USL = upper specification limit**Specification limits are based on target values established by the supplierσ = estimated standard deviation4.2.2 The alternative test plan shall contain the following:4.2.2.1 Statistical analysis of the heat treatment process parameters and the product test results of properties forcontrol and capability (See 3.5).4.2.2.2 Documentation of the critical process parameters and of the product test results of properties on a control plan(See 3.5). A change in these process parameters of product test results will require review to determine if the process capability requires reverification.4.2.2.3 Periodic auditing of the heat treatment process parameters and the product test results of properties to verifycontinued control and capability (See 3.5).4.2.2.4 Monthly, or whenever needed by either the cognizant engineering authority or process constraints,decarburization shall be examined in accordance with 3.5.1.5. PREPARATION FOR DELIVERYIn accordance with AMS2759.6. ACKNOWLEDGMENTIn accordance with AMS2759.7. REJECTIONSIn accordance with AMS2759.8. NOTESIn accordance with AMS2759 and the following:8.1 A change bar (l) located in the left margin is for the convenience of the user in locating areas where technicalrevisions, not editorial changes, have been made to the previous issue of this document. An (R) symbol to the left of the document title indicates a complete revision of the document, including technical revisions.

It is most often used prior to a refrigeration cycle. Final tempering to the specified requirements is performed after snap tempering.8.5.2 Marquenching(Martempering)Quenching an austenitized alloy in a salt or hot oil bath at a temperature in the upper part of, or slightly above, the martensite range and holding until temperature uniformity throughout the part is obtained, usually followed by air cooling through the martensite range to ambient temperature.8.6 Dimensions and properties in inch/pound units and the Fahrenheit temperatures are primary; dimensions andproperties in SI units and the Celsius temperatures are shown as the approximate equivalents of the primary units and are presented only for information.PREPARED BY AMS COMMITTEE “E” AND AMECTABLE 2A - ANNEALING, NORMALIZING, AND AUSTENITIZING TEMPERATURES AND QUENCHANTS,INCH/POUND UNITSMaterial DesignationAnnealing (1)Temperature, °FNormalizingTemperature, °FAustenitizing (2)Temperature, °FHardeningQuenchant4330V, 4330M (2) 4335, 4335M (2) 4340 (2)Hy-Tuf (2)300M (2)4340 Mod (2)H-11 (3)98BV40 (2)D6AC (2)521009Ni-4Co-0.30C (2) (5) M-50AF1410 (2) (5) AerMet ® 100 (2)157515501550140015501550160015501550( 6)( 8)--1650 (12)--165016501650172517001700--1600172516501700( 9)1650 (12)1650 (13)160016001500 (16)160016001600185015501625 (4)1550 (7)15502025 (10)15251625oil, polymeroil, polymeroil, polymeroil, polymeroil, polymeroil, polymerair, oil, polymeroil, polymeroil, polymeroil, polymer (5) (15)oil, polymer (5)salt (11)oil, polymer (5)air, oil, polymer (14)NOTES:1.
