Abstract (en)
[origin: WO2015014333A2] The invention relates to a high-strength multi-phase steel having minimum tensile strengths of 750 MPa and preferably having a dual-phase microstructure for a cold- or hot-rolled steel strip, in particular for lightweight vehicle construction, said high-strength multi-phase steel having improved forming properties and a ratio of yield point to tensile strength of at most 73%. The high-strength multi-phase steel consists of the elements specified in claim 1 (contents in mass %), the remainder iron, including typical elements accompanying steel that are not mentioned above, which represent contamination resulting from smelting.
