Abstract (en)
[origin: EP0747496A1] Steel sheet comprises 0.5-1.5wt.% Mn, 0.01-0.1% Al and up to 0.12% C, 0.3% Si, 0.1% P, 0.05% S, 1% Cr, 0.05% Nb, also 0.03-0.15% Ti not in the form of nitrides, sulphides or oxides. The structure comprises at least 75% of ferrite hardened by precipitation of carbides or carbonitrides of Ti or of Ti and Nb, the remainder comprising at least 10% martensite and possibly bainite and austenite. Also claimed are methods of making the steel sheet by hot-rolling followed by controlled cooling.
