热轧双相钢一般用于需高强度、高的抗碰撞吸取能且有一定成型要求的汽车零件，如车轮、保险杠、悬挂系统及其加强件等。热 轧双相钢具有强度高、屈强比低、初时加工硬化率高以及强度和韧性良好配合等优点，符合汽车材料轻量化、高性能、安全、环保、 节能的发展主题，从而在汽车行业得到了较为广泛的应用。
The hot rolled dual-phase steel is generally used for automotive parts with high strength, high impact resistance and absorbing energy and should meet a certain forming requirement, such as wheels, bumpers, suspension systems and their reinforcing parts. The hot rolled dual phase steel is provided with high strength, low yield ratio, high initial processing hardening rate, excellent matching between strength and toughness and other advantages, in line with the development theme of lightweight, high performance, safety and environmental protection, energy saving for automotive materials, which has thus been widely used in the automotive industry.
