GNEE Steel Hot Rolled Automotive Steel
The amount of automobile steel used has increased rapidly with the rapid development of China's economy. In recent years, the requirements for lightweight automobiles have also increased, and high-strength steel, advanced high-strength steel or ultra-high-strength steel have become more and more widely used.

Commonly used cold-rolled automotive steel types
1. Phosphorus-added high-strength cold-rolled steel plates add a certain amount of phosphorus to low carbon steels or ultra-low carbon steel, and use the solid solution strengthening effect of phosphorus to increase the strength of the steel, which can reduce the weight of the car and is also used to manufacture cross beams and beams of the car. Stringer.
2. Bake-hardened high-strength cold-rolled steel plates Bake-hardened high-strength steels (BH steel) uses a specific chemical composition and production process to dissolve a certain amount of carbon atoms in the steel. The steel plate has a lower yield strength, and during stamping The yield strength increases to a certain extent when paint is dried after forming. This is a new type of automotive steel plate that is widely used in the automotive industry.
