Patent abstract
A low-nickel austenitic stainless steel is provided which comprises by weight: ≦0.08% C, 4.0˜5.0% Mn, 0.7˜1.0% Si, 3.5˜4.5% Ni, 16.0˜18.0% Cr, 3.0˜3.50% Cu, ≦0.045% S, ≦0.030% P, impurity elements in the total amount of ≦0.2%, and Fe as the balance. This low-nickel austenitic stainless steel has decreased nickel content, but retains excellent mechanical properties and corrosion resistance property. Therefore, the cost for producing the stainless steel can be reduced remarkably. The method for producing the low-nickel austenitic stainless steel is also provided.
