Chinese steel giant BaoSteel has recently developed 1.5GPa ultra high strength gigapascal cold rolled dual phase steel for lightweight automotive. The low alloy highly formable DP1500 CR was jointly developed by Baosteel and a customer. The target part is a new model beam, which requires good bending performance on the basis of ultra-high strength and high elongation and low risk of delayed cracking. The automotive sheets of this strength have been used for butt welding of bumpers, anti-collision beams, seat beams, battery pack frames, etc.Giga steel refers to high-strength automotive steel with a tensile strength of more than 1000 MPa, which has the characteristics of high strength, high elongation, good bending properties, high yield ratio and high hole expandability.
