1.4313调质热处理+QT700调质+QT780/调质(+QT900)

1.4313是马氏体级，耐腐蚀性高，热处理后耐久性好。X3CrNiMo13-4钢的机械性能是由于化学成分中钼和镍的高含量。这些合金添加剂限制了增加a级碳含量的需要——给定浓度相当于奥氏体不锈钢。虽然镍含量不高，但镍含量约为4%，显著提高了钢对各种腐蚀环境的抵抗力——二次机械性能。X3CrNiMo13-4钢用户可生产高达300℃在温度下工作的零件和零件，以及暴露在各种腐蚀环境中的零件，同时保持足够的表面条件括抗氯化物性质)。QT650.QT780和QT900条件下。半成品用于石油生产.化工.在冶金和能源行业，涡轮机暴露在高温和低温下.泵.压缩机部件。钢不适合焊接。
