Abstract

PURPOSE: To provide an austenitic stainless which retains sufficient strength and corrosion resistance even when the crystal grains are coarse, by decreasing C content of the steel, and by addn. of limited amount of N, Nb.
CONSTITUTION: An austenitic stainless steel comprising, by weight, <0.02%C, ≤1.0%Si ≤2%Mn, 17.0W19.0%Cr, 9.0W13.0%Ni, 0.08W0.15%N, 0.1W1.0%Nb, the balance being substantially Fe. This alloy steel is manufactured by decreasing carbon content in order to improve corrosion resistance, and by limiting the quantity of N and Nb to be added in order to prevent decrease in strength at high temp. and at ordinary temp. Hereby, this alloy steel can be used suitably as a material for products, such as castings or heavy plates, which are made at a small reduction ratio and require corrosion resistance and high strength.
