一、不锈钢材料耐点腐蚀、晶间腐蚀和应力腐蚀能力的顺序（由小到大）

1、奥氏体不锈钢：

1Cr18Ni9Ti →0Cr18Ni9（304>）→0Cr18Ni11Ti（321）→00Cr19Ni10（;304L）0Cr17Ni12Mo2Ti（316）→00Cr17Ni14Mo2（316L）→00Cr19Ni13Mo3（317L）→00Cr20Ni25Mo4.5Cu<;FONT face=宋体>（904L）→00Cr27Ni31Mo4Cu

2、 ;铁素体不锈钢：

0Cr13（410S）→0Cr13Al（405）→00Cr12Ti（409L）→00Cr17（430LX）→00Cr18Mo2 →00Cr26Mo1 →00Cr30Mo2

3、双相不锈钢：

00Cr18Ni5Mo3Si2（3RE60）→00Cr22Ni5Mo3N（SAF2205）→00Cr25Ni7Mo4N;（SAF2507）

二、耐高温腐蚀用材的顺序

20＃→12Cr1MoV→12Cr2Mo1（2 Cr-1Mo）→;1Cr5Mo→1Cr9Mo→P91(10Cr9Mo1VNb） ;→0Cr25Ni20(310S)

三、耐应力腐蚀用材

16MnR;→20R→12Cr1MoV

00Cr17Ni14Mo2（316L）→00Cr19Ni13Mo3（317L）→00Cr20Ni25Mo4.5Cu（904L）→

00Cr18Ni5Mo3Si2（3RE60）→00Cr22Ni5Mo3N（SAF2205）→00Cr25Ni7Mo4N（SAF2507）

0Cr13（410S）→00Cr12Ti（409L）→00Cr17（430LX）→00Cr18Mo2 →00Cr26Mo1
