PURPOSE: To provide a stainless steel excellent in oxidation resistance, wear resistance, and strength at high temp. as well as in weldability. CONSTITUTION: This alloy has a composition consisting of <=0.100% C, 1.50-4.00% Si, <=2.00% Mn, 0.05-2.00% Cu, <=0.040% P, <=0.010% S, 15.0-30.0% Cr, 8.0-15.0% Ni, 0.15-0.30% N, 0.001-0.010% B, 0.01-0.10%, in total, of one or >=2 kinds among Ca and rare earth elements, such as Y, La, and Ce, 0.01-0.10% Al, and the balance essentially Fe. Further, the Ni valance value, represented by [%Ni+0.5×(%Mn+%Cu)+30×(%C+%N)--1.1×(%Cr+1.5×%Si)+8.2], is regulated to -1.00 to +2.00%.
