冷库保温隔热板的表层1.4313是马氏体级，耐氧化高朝，热除理后耐久度性好。X3CrNiMo13-4钢的机的功能是基于化学工业成份中钼和镍的高份量。一些和金调用剂局限了加强级碳份量的须得——给定酸度非常的于奥氏体冷库保温隔热板的表层。既然镍份量低，但镍份量约为4%，有效加快了钢对多种多样氧化坏境的驱散力——第二次机的功能。X3CrNiMo13-4钢微信用户可生育高达模型300℃在工作任务温度下工作任务的机件和机件，、露出在多种多样氧化坏境中的机件，一同保持稳定充裕的漆层要求括抗氯化物概念)。QT650.QT780和QT900要求下，热除理后最喜欢交工形钢。半产生设备于油田生育.煤化工.在有色金属和新能源的行业，增压机露出在高温柔恒温下.泵.缩短机构件。钢痛感合氩弧焊。
