Abstract (en)
[origin: EP0492576A1] A high strength chromium containing steel sheet having a tensile strength of at least 40 kgf/mm<2>, and excellent in corrosion resistance and workability, comprising, by weight, C:up to 0.030 %, Si:up to 3.0 %, Mn:up to 3.0 %, P:up to 0.150 %, S:up to 0.010 %, Ni:up to 2.0 %, Cu:up to 2.0 %, 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 > 1.0 % may be satisfied, the balance being iron and unavoidable impurities.
