≤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.
