| Abstract: | 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. |
