Abstract

The invention relates to a flat steel product, having a tensile strength Rm + 950 MPa, a yield strength + 800 MPa and an elongation at break A50 + 8%. According to the invention, the flat steel product consists of steel which is composed of (in weight-%) 0.05 - 0.20% C, 0.2 - 1.5% Si, 0.01 - 1.5% Al, 1.0 - 3.0% Mn, = 0.02% P, = 0.005% S, = 0.008% N, and in each case optionally 0.05 - 1.0%, 0.05 - 0.2% Mo, 0.005 - 0.2% Ti, 0.001 - 0.05% Nb, 0.0001 - 0.005% B, the remainder being Fe and inevitable impurities, wherein: 1.5 = ? = 3, with ?= (%C+%Mn/5+%Cr/6) / (%Al+%Si) and %C, %Mn, %Cr, %Al, %Si being the respective C, Mn, Cr, AI or Si content of the steel. At the same time the flat steel product has a structure which consists of (in area percentage) = 5% bainite, = 5% polygonal ferrite, + 90% martensite and = 2% by volume residual austenite, at least half of the martensite being tempered martensite. The invention also relates to a method for producing such a flat steel product.
