What is the material of automobile high strength steel?

　　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 grade S700MC steel, which has high strength, especially in normalizing or normalizing and tempering state with high comprehensive mechanical properties. Mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, lifting machinery, mining machinery and other large-scale welding structural parts.
