Abstract: A cold-rolled flat steel product has a tensile strength of 750-940 MPa, a high strength, an improved weldability and optimized shaping properties, and can be produced at low cost. The cold-rolled flat steel product consists of a steel composed, in percent by mass, of C: 0.040-0.100%; Mn: 2.10-2.50%; Si: 0.10-0.40%; Cr: 0.30-0.90%; Ti: 0.020-0.080%, B: 0.0005-0.0020%; N: 0.003-0.010%; Al: up to 0.10%; Ca: up to 0.005%; P: up to 0.025%; S: up to 0.010%; optionally one or more of the following elements: Mo: up to 0.20%; Nb: up to 0.050%; Cu: up to 0.10%; V: up to 0.020%; Ni: up to 0.10%, the remainder being iron and unavoidable impurities, and total content of impurities is limited to at most 0.5% by mass and contents of phosphorus (“P”) and sulfur (“S”) belong to the impurities.
