ASTMA6931993沉淀硬化不锈钢和耐热钢厚板、薄板和钢带

1、ASTMA693-1993沉淀硬化不锈钢和耐热钢厚板、薄板和钢带创建时间：2008-12-29ASTMA693-1993沉淀硬化不锈钢和耐热钢厚板、薄板和钢带沉淀硬化不锈钢和耐热钢厚板、薄板和钢带的力学性能是通过一般称作“沉淀硬化”的适当的低温热处理来得到。这些钢用作要求耐腐蚀和在室温或在达315C高温具有高强度的零件。其中有些钢特别适于在固溶热处理状态进行中等的至严厉的拉拔和成形。其他一些钢仅能进行轻度成形。这些钢适于在固溶退火状态进行机加工。在同溶退火后，这些钢可以被硬化到标准规定的力学性能。而没有破裂或变形的危险。制造方法钢应按下列种方法冶炼：电炉(带有独立的脱气和精炼装置)；真空炉；电

2、炉或真空炉冶炼，随后在真空中或惰性气体中自耗重熔，或电渣重熔，或进行电子束精炼；供需双方协商同意的其他常用的冶炼方法。牌号和化学成分钢的牌号和化学成分见表1。表1牌号和化学成分1)UNS代号1)牌号CMnPSSiCrS174006300.071.000.0400.0301.0015.00-17.50S177006310.091.000.0400.03J1.0016.00-18.00S157006320.091.000.0400.031.0014.00-16.00S350S330.07-0.0.50-1.0.0400.0300.5016.00-17001125.00S3556340.10-0.0
