Abstract:
A high-strength multi-phase steel having minimum tensile strengths of 750 M:Pa and preferably having a dual-phase microstructure for a cold- or hot-rolled steel strip, in particular for lightweight vehicle construction is disclosed. The high-strength multi-phase steel has improved forming properties and a ratio of yield point to tensile strength of at most 73%. The high-strength multi-phase steel includes in mass %: C≥0.075 to ≤0.105; Si≥0.600 to ≤0.800; Mn≥1.000 to ≤0.700; Cr≥0.100 to ≤0.480; Al≥0.010 to ≤0.060; N 0.0020≤0.0120; S≤0.0030; Nb≥0.005 to ≤0.050; Ti≥0.0050 to ≤0.050; B≥0.0005 to ≤0.0040; Mo≤0.200; Cu≤0.040%; Ni≤0.040 % the remainder iron, including typical elements accompanying steel that are not mentioned above, which represent contamination resulting from smelting.

Claim (Index 1):
