马氏体钢分子式：CAS号：性质：使用状态下，具有马氏体显微组织的钢。按成分与热处理工艺性能、用途等的不同有马氏体不锈钢、马氏体沉淀硬化不锈钢、马氏体耐热钢和马氏体时效钢。马氏体不锈钢含铬量13%～18%，淬火回火状态下使用，用于汽轮机叶片（含碳较低的），医疗手术工具、测量工具、弹簧等（含碳较高的）；马氏体沉淀硬化不锈钢，铬镍含量比前者为高、经高温固溶、淬火后，再在400～500℃时效处理，在马氏体基体内析出大量与基体操持共格关系的第二相，用于化工压力容器、飞行器的结构等。马氏体耐热钢含铬7.5%～20.5%，含碳0.15%～0.85%和多种合金元素，在650～700℃回火，形成细微碳化物分散于基体中，主要用于汽车等发动机的阀门、涡轮机叶片、喷嘴、螺栓等。马氏体时效钢，含镍较高18%～25%、含钼5%、含钴8%及少量钛和铝，经固溶空冷后再在480℃时效处理。马氏体内析出金属间化合物而强化，因成本高，一般用于航空、航天及海洋技术中重要结构件，如火箭发动机壳体、飞机起落架、重要的模具等。
