With the rapid development of the social economy, there are more and more cars now. However, the outer casing of the car is usually made of iron, which is easy to rust, so an additional layer of paint is needed to protect the practical life of the car casing. In the face of this situation, some car owners said, so that is the case, then why not use stainless steel to make cars? This also saves money on a painted surface, and the master has also told the truth.
In fact, the earliest cars did not have a painted surface, or a thin layer of paint. At that time, the problem of rusting of the car was rampant, and it would take a long time for a car to be scrapped. With the development of automotive technology, people now know that rusting is prevented by painting, but in some places that are difficult to cover, the rust of the vehicle still exists. Car rust will not only affect the appearance, but also the oxidation of iron will become unstable and contain bacteria.
Whether it is at home or abroad, car rust is a very difficult problem, but stainless steel manufacturing cars, there are also a lot of trouble. The first is the problem of the weight of stainless steel. Now car companies are trying their best to reduce the weight of the car, so that not only fuel consumption, but also the car performance will be better. If stainless steel is used, the car will increase fuel consumption by increasing the weight, which is not worth the effort.
Immortal Gang does not rust because it adds a lot of carbon, so its antioxidant effect is good. The hardness of carbon is not high, so the stainless steel will be soft. When welding, the plasticity of stainless steel is too strong. If you are not careful, you will see a deformation of the car structure. And the cost of stainless steel is higher than that of iron sheet, and the price of stainless steel is generally about three times that of ordinary steel.
Again, because the stainless steel surface is smooth and the reflection is strong, the stainless steel has to be wrapped with a layer of paint. Otherwise, the glare reflected during the day may affect the sight of other owners and cause an accident. Now some car owners will install stainless steel fittings on the insignificant parts such as the doorpost, which is also a good anti-rust method.
