1、奥氏体/马氏体/铁素体奥氏体（钢的组别：A1, A2, A3 A4, A5） (性能等级：50软，70冷加工，80高强度)马氏体(钢的组别：C1,C2,C3) (性能等级：50软，70、110淬火并回火，80淬火并回火)铁素体(钢的组别：F1) (性能等级：45软，60冷加工)马氏体不锈钢属于铬不锈钢。由于含碳量高，碳化铬多，钢的耐蚀性能下降，虽可通过热处理的方法改善，但防腐性不高。马氏体不锈钢多用于制造力学性能要求较高，并有一定耐蚀性能要求的零件，如汽轮机叶片、喷嘴、阀座、量具、刃具等。铁素体不锈钢也属于铬不锈钢。含碳量小，抗大气、硝酸及盐水溶液的腐蚀能力强，有高温抗氧化性能好等特点。主要用
2、于制作化工设备中的容器、管道。奥氏体不锈钢属于铬镍不锈钢。具有很高的耐蚀性，优良的塑性，良好的焊接性及低温韧性，不具有磁性，易加工硬化。主要用于在腐蚀介质中工作的零件、容器、管道、医疗器械以及抗磁环境中。马氏体、铁素体、奥氏体、双相不锈钢的化学成分类型钢 号牌 号化学成分 %CCrNiMnPSMoSiCuN其它奥氏体型2011Cr17Mn6Ni5N0.1516.00-18.003.50-5.505.507.500.0600.030-1.00-0.25-201L03Cr17Mn6Ni5N0.03016.00-18.003.50-5.505.507.500.0600.0301.000.252021
