Automotive steel is important, cost considerations are the key

A car is a smart machine, and there are many steel or metal parts. The car body exists as a vehicle that carries all the configurations of the entire car and cab. The body has a very large proportion of the cost for the entire car. Therefore, many car companies will do enough articles on the body to maximize cost savings and increase profit margins. So how is the car body made and manufactured?

The body-in-white is made up of several sheets of steel joined together by welding. However, the steel used in the entire body is a low alloy steel. The biggest advantage of low alloy steel is that it has good processing performance and the steel itself has high mechanical strength. At the same time, low-alloy steel has better corrosion resistance than ordinary steel. In the natural environment, a layer of brown and dense oxide layer will be formed on the surface of low-alloy steel. This layer of oxide is a good way to isolate the internal steel from the outside air. , better play a role in rust prevention.

One of the representatives of low-alloy steel is weathering steel. The biggest characteristic of weathering steel is that it is very resistant to weathering. Weathering steel is usually used at the bottom of the car body, because the bottom of the car is directly exposed, and it is closely related to the ground and the driving environment and is more likely to be corroded by the environment. Therefore, the use of weathering steel is particularly important.
