Abstract
A steel sheet which has a chemical composition that contains, in mass%, from 0.14% to 0.60% of C, 3.00% or less of (Si + Al), 0.030% or less of P, 0.0050% or less of S, 0.015% or less of N, 0.0050% or less of B, 0.80% or less of (C à Mn), 0.80% or more of (Mn + Ni + Cu + 1.3Cr + 4(Mo + W)), from 0.003% to 0.20% of (Ti + Zr + Hf + V + Nb + Ta + Sc + Y), 0.020% or less of (Sn + As + Sb + Bi), from 0% to 0.005% of Mg, from 0% to 0.005% of Ca and from 0% to 0.005% of REM, with the balance being made up of Fe and impurities, while satisfying Ms = 546 à exp(-1.362 à C) - 11 à Si - 30 à Mn - 18 à Ni - 20 à Cu - 12 à Cr - 8(Mo + W) ⥠200. This steel sheet has a metal structure which contains, in area%, 85% or more of martensite and 15% or less of residual austenite, with the balance being made up of bainite, while having an average block grain diameter of martensite and bainite of 3.0 μm or less, an average axial ratio of martensite and bainite of from 1.0004 to 1.0100, and a yield stress of 1,000 MPa or more.
