| Abstract: | Nitrogen alloying process was set up by theories of nitrogen dissolved and degassed in stainless steel refined in AOD. This process was applied in stainless steels with nitrogen, such as 0Cr19Ni9N, 0Cr19Ni9NbN, 1Cr17Mn6Ni5N, 00Cr18Ni5Mo3Si2(N), 00Cr22Ni5Mo3N, which were refined in AOD of 40 t. The result showed that analysis of nitrogen content in stainless steel on-line was not necessary. The process could achieve that nitrogen solubility was exactly controlled, and so did the nitrogen content of stainless steel with nitrogen. |
