汽车高强度钢材的材料是什么？
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.具有高强度的钢，尤其是具有高综合力学性能的归一化或归一性和回火状态。主要用于大型船舶，桥梁，发电站设备，中高压锅炉，高压容器，轧机，升降机械，采矿机械等大型焊接结构件。
