摘要
PROBLEM TO BE SOLVED: To provide a ferritic stainless steel sheet in which sufficient corrosion resistance can be secured even regarding dissimilar welds with an austenitic stainless steel (e.g., SUS304).;SOLUTION: The ferritic stainless steel sheet has a composition comprising, by mass, ≤0.030% C, ≤0.030% N, ≤0.050% (C+N), 0.15 to 0.60% Si, ≤0.50% Mn, ≤0.010% Al, 20.5 to 22.5% Cr, 0.03 to 1.00% Cu, 0.10 to 1.50% Ni, 0.30 to 0.70% Nb, ≤0.040% P and ≤0.010% S, and in which these components satisfy the relation in inequality; Nb/(C+N+0.06)≥4, and the balance Fe with inevitable impurities.;COPYRIGHT: (C)2008,JPO&INPIT
