| Abstract: | A new as-cast ultra-low carbon low nickel medium nitrogen austenite stainless steel 022Cr20Mn10Ni6N (%:0.023～0.027C,9.86～9.95Mn,19.24～20.09Cr,5.41～5.42Ni,0.27～0.34N)is melted by a 15 kg medium induction furnace,and the structure,mechanical properties and corrosion resistance of as-cast steel 022Cr20Mn10Ni6N and as-cast steel 304(%:0.076C,1.87Mn,18.02Cr,8.64Ni)have been tested and studied.Results show that the mechanical properties,pitting corrosion resistance and anti-weak acid and weak alkali even corrosion of the new as-cast stainless steel are better than that of as-cast stainless steel 304,its neutral salt spray corrosion resistance is equal to as-cast steel 304.The new as-cast steel 022Cr20Mn10Ni6N can meet the application requirement of glass curtain wall metal connector in atmospheric environment. |
