钢材性能对比表[za]

常用钢材的性能对比
钢主要分为：生铁、铁合金、普通碳素结构钢、优质碳素合金钢、碳素工具钢、切削钢、电工用钢、合金钢。

而我们集装箱上用的钢属于普通碳素结构钢和低合金碳素钢系列。

下表为常用箱用钢材的简介：
耐候钢分为高耐候钢和焊接耐候钢。

●高耐候钢：适用于海洋性大气环境，其耐腐蚀性能优于焊接耐候钢，但对于焊接性能较高的场合不太适用。

高耐候钢的牌号主要有：Q265GNH、Q295GNH、Q310GNH、Q355GNH等。

●焊接耐候钢：使用于陆地大气环境，其耐腐蚀性和焊接性能优良。

焊接耐候钢的牌号主要有：Q235NH、Q355NH、Q415NH、Q460NH等。

常用刀具钢材特性“不锈钢”这个词常常让人误解，因为事实上没有钢材是不生锈的，生锈会在钢材上留下污点，并使刀具状态欠佳。

熔炼时在钢材中加入铬，并降低碳的含量，就可以使其成为“不锈钢”。

有些专家认为，不锈钢的表现具有矛盾性：增多铬减少碳能增强抗锈能力，但也使刀刃更难于打磨锋利，刀锋持久性也会降低。

但我们发现多数的不锈钢刀刃能够于其它材料的刀刃一样锋利，且持久性也一样。
