Abstract

PURPOSE: To inhibit deterioration in the corrosion resistance of a ferrite stainless steel for bright annealing finish during annealing finish by combinedly adding Nb and Cu and restricting the Mn content.
CONSTITUTION: This ferrite stainless steel for bright annealing finish has a composition consisting of, by wt., 0.05W0.8% available Nb represented by equation I, 0.2W1.0% Cu, ≤0.7% Mn, 11.5W22.0% Cr, ≤0.03% C, ≤0.025% N, ≤0.01% S, ≤0.01% O, ≤1.0% Si and the balance Fe with inevitable impurities or further contg. ≤1.5% Mo and/or ≤1.5% Ni. This stainless steel does not deteriorate the corrosion resistance during bright annealing finish.
