PURPOSE:To obtain a high-alloy stainless steel with high corrosion resistance and superior hot workability by adding specified amounts of C, Si, Mn, Cr, Ni, Mo and N and by further adding B in combination with Al and REM while restricting the S content to a specified amount or less. CONSTITUTION:The composition of a high-alloy stainless steel is composed of, by weight, <0.05% C, 0.1-1% Si, <2% Mn, 15-30% Cr, 10-30% Ni, 0.5-4% Mo, 0.05-0.4% N, <0.1% S, 0.02-0.1% Al, 0.005-0.1% REM, 0.005-0.01% B and the balance Fe with inevitably contained impurities.
