US20160222486A1 MANUFACTURING METHOD FOR VERY HIGH-STRENGTH, COLD-ROLLED, DUAL-PHASE STEEL SHEETS AND SHEETS SO PRODUCED 审中-公开
非常高强度，冷轧，双相钢板和生产的板材的制造方法

MANUFACTURING METHOD FOR VERY HIGH-STRENGTH, COLD-ROLLED, DUAL-PHASE STEEL SHEETS AND SHEETS SO PRODUCED
Abstract:
The present invention provides a cold-rolled and annealed Dual-Phase steel sheet having strength from 980 to 1100 MPa and a breaking elongation greater than 9%. 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+2Mo≦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 manufacturing method is also provided.
