马氏体型、奥氏体型、铁素体和双相不锈钢代表钢号、化学成分、室温力学性能及标准钢号对照表
代表钢号、化学成分、室温力学性能:
马氏体不锈钢的代表钢号为1Cr13、2Cr13、3Cr13、4Cr13等,铁素体不锈钢的代表钢号为1Cr17、1Cr17Ti、 1Cr25等,奥氏体不锈钢的代表钢号为1Cr18Ni9Ti、0Cr18Ni9(304)、00Cr18Ni9Ti(304L)、 0Cr17Ni12Mo2(316)、00Cr17Ni14Mo2(316L)、0Cr18Ni11Ti(321)、0Cr18Ni11Nb(347) 等,双相不锈钢的代表钢号为00Cr26Ni7Mo2Ti等。
为了清楚,将它们列表来说明见表1、表2、表3。
