【摘要】 在实验室采用200 kg非真空感应炉研制了成分(％)为:≤0．10C,5．0-9．5Mn,16．0-19．0Cr, 3．5～5．5Ni,1．0～2．0Cu,≤0．2N的奥氏体不锈钢YGA201。力学性能和腐蚀试验结果表明,YGA201不锈钢含1．0％-2．0％Cu,使其1 050℃固溶处理后的延伸率达60％,高于ASTM201不锈钢(延伸率44％),该钢热加工性能和1 mol／L H2SO4中的耐腐蚀性能与SUS304(18Cr-8Ni)不锈钢相当。更多还原

【Abstract】 The austenite stainless steel YGA201-≤0.10C, 5.0 - 9.5Mn, 16.0 - 19.0Cr, 3.5 - 5.5Ni, 1.0 -2.0Cu,≤0.2N has been melted and studied by a 200 kg induction furnace in laboratory. The mechanical properties and corrosion test results showed that the elongation of 1 050℃solid solution heat treated YGA201 stainless steel containing 1.0% - 2.0% Cu was up to 60% , higher then that of ASTM201 stainless steel (elongation 44%), and its hot workability and corrosion resistance in 1 mol/L H2SO4 were equal to SUS304 (18Cr-8Ni) stainless steel.更多还原
