  • VERY HIGH-STRENGTH, COLD-ROLLED, DUAL STEEL SHEETS
    Publication number: 20190106765
    Abstract: The present invention provides a cold-rolled and annealed Dual-Phase steel sheet having a tensile strength from 980 to 1100 MPa. The composition includes the contents being expressed by weight: 0.055%?C?0.095%, 2%?Mn?2.6%, 0.005%?Si?0.35%, S?0.005%, P?0.050%, 0.1?Al?0.3%, 0.05%?Mo?0.25%, 0.2%?Cr?0.5%, Cr+2 Mo?0.6%, Ni?0.1%, 0.010?Nb?0.040%, 0.010?Ti?0.050%, 0.0005?B?0.0025%, and 0.002%?N?0.007%. The remainder of the composition includes iron and inevitable impurities resulting from the smelting. A microstructure of the steel sheet is 40 to 65% ferrite, 35 to 50% martensite and 0 to 10% bainite. A non-recrystallized ferrite fraction is less than or equal to 15%.
