| 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 1050 ℃ solid solution heat treated YGA201 stainless steel containing 1.0%~2.0% Cu was up to 60%, higher than 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. |
