Chromium containing steel sheet excellent in corrosion resistance and workability

Abstract

A chromium containing steel sheet excellent in corrosion resistance and workability, comprising, by weight, C:up to 0.030%, Si:up to 0.5%, Mn:up to 0.5%, P:up to 0.040%, S:up to 0.010%, Ni:up to 0.3%, Cu:up to 0.3%, Cr: not less than 5.0% and less than 11.0%, N:up to 0.030%, V:not less than 0.01% and not more than 0.10%, and optionally at least one of 0.01 to 0.30% of Ti, 0.01 to 0.30% of Nb, 0.01 to 0.30% of Zr, 0.01 to 0.20% of Al and 0.0002 to 0.0200% of B, the amounts of Si, Mn, P, Ni and Cu being adjusted so that the relation:Si+Mn+10P+Ni+Cu.ltoreq.1.0% may be satisfied, the balance being iron and unavoidable impurities.
