| Abstract: | The high nitrogen austenite stainless steel 1Cr22Mn15N-0. 12C,0.42Si,14.96Mn,0.026P,0.001S, 22.57Cr,0.56N has been produced using primary metal-1.84C,2.18Mn,24.88Cr by 20 t AOD refining - blowing O?,N?,adding electrolytc manganese,silicon iron and aluminium pig and adding NCr alloy to micro-adjusting composition of steel.The 590 kg ingot cast by refining steel and bloomed to 135 mm x 157 mm billet then continuously rolled to 8~12 mm round bars. The yield strength of finished product solid - solution - treated was 565～585 MPa,tensile strength 920~955 MPa,elongation 54.5%～56.5% and had excellent corrosion resistance. |
