Abstract (en)
[origin: WO2020104437A1] A high strength steel sheet with an ultimate tensile strength (Rm) of at least 950 MPa and a thickness accuracy better than 1/5 of EN 10143:2006 normal thickness tolerances, which steel sheet has a composition consisting of, in terms weight percentages, 0.07 % -0.13 % C, 0.1 % -0.3 % Si, 2.3 % -3.0 % Mn, 0.2 % -0.5 % Cr, 0.02 % -0.05 % Ti, 0.002 % -0.01 % B, ≤ 0.2 % Mo, ≤ 0.2 % V, ≤ 0.2 Cu, ≤ 0.5 % Ni, ≤ 0.005 % Ca, ≤ 0.1 % Al, ≤ 0.05 % P, ≤ 0.01 % S, ≤ 0.008 % N and the remainder being Fe and inevitable impurities.
