汽车高强度钢的材料是什么?

　　For more than 100 years, steel has been the foundation of the automotive industry. Although the amount of plastics and aluminum-magnesium alloys in automobile manufacturing continues to increase, steel materials are still the main body of automotive materials. Choosing a low-thickness high-strength steel plate to replace the traditional low-strength steel plate is an effective method for automobile lightweighting. Compared with aluminum, magnesium alloys and composite materials, high-strength steel plates have lower raw materials and manufacturing costs, making them more competitive in the application of new automotive materials.

　　High-strength steel plate refers to Q460 gradeS700MC钢，具有较高的强度，特别是在正火或正火回火状态下具有较高的综合力学性能。主要用于大型船舶、桥梁、电站设备、中高压锅炉、高压容器、机车车辆、起重机械、矿山机械等大型结构件的焊接。
