摘　　要：一种新型的资源节约型高氮超级双相不锈钢00Cr25N i2Mo3Mn10N开发出来,氮质量分数达到0.5%.研究表明,经热锻和1 050℃固溶处理后,基体组织由铁素体和奥氏体组成,铁素体质量分数约为47%,氮质量分数的增加能明显提高材料的机械性能和腐蚀性能.通过对比研究表明,00Cr25N i2Mo3Mn10N的综合性能相当于或优于00Cr25N i7Mo4N超级双相不锈钢.A new resource-saving high nitrogen super duplex stainless steel 00Cr25Ni2Mo3Mn10N has been developed, in which the nitrogen content reaches 0.5%. The results indicate that the alloy is made up of ferrite and austenite after hot forge and 1 050℃ solid solution treatment, and the ferrite content is about 47%. Mechanical and corrosion property are noticeably enhanced with the increase of nitrogen. The comprehensive performance of 00Cr25Ni2Mo3Mn10N alloy is as good as that of 00Cr25Ni7Mo4N super duplex stainless steel, and even better.
