Audi a2 Hot Formed Steel Proportion

The ratio of hot-formed steel to biw is 16%.

Hot-formed steel plate technology refers to that the steel plate is heated at a high temperature of 950℃ and then formed once, and then cooled quickly, thus improving the strength of the steel plate in an all-round way. The yield reaches 1000 MPa, and it can bear more than 10 ton per square centimeter. When this material is used in the car body, the bearing capacity is increased by 30% and the stiffness and strength of the car body reach a new level with almost no change in the weight of the car body.

The strength of a car body depends on the design of the car body and the strength of the steel plate, so the strength of the steel plate in the important protective parts of the car body is very important, and the thermoformed steel plate is undoubtedly the best among all kinds of high-strength steel plates.
