Do you know the application of precision stainless steel in the automotive industry?

The automotive industry is the fastest growing stainless steel application area today. In the past ten years, the sales volume of stainless steel used in automobiles in Japan has increased from an average of 10 kg to 30 kg. As early as 1987, my country used stainless steel to produce vehicles, and large amounts of stainless steel were also used in transportation vehicles such as buses, subways, and high-speed railway vehicles. With the improvement of living standards and economic development, the market's demand for high-end vehicles has greatly increased. Lightweight and high-grade stainless steel rail vehicles will be the main development direction of rail vehicles in the future. Specific applications (1) Stainless steel used in automobile exhaust systems As the stainless steel material for exhaust gas of automobiles, in addition to high temperature resistance strength and high temperature oxidation resistance, it also needs to have high temperature corrosion resistance and thermal fatigue characteristics. (2) Stainless steel for automotive fuel tanks Stainless steel for automotive fuel tanks is mainly stainless steel plates, which are required to have internal fuel corrosion resistance and external corrosion resistance to harsh environments. (3) Stainless steel for automobile frames The stainless steel used for automobile frames has good toughness, plasticity, formability and weldability while ensuring high enough strength. The automobile frame made of stainless steel is not only light in weight, safe and reliable, but also has a long service life. In addition, when the car is scrapped, the stainless steel frame can also be recycled, which can be described as killing two birds with one stone. (4) Automobile stainless steel parts Most automobile parts are made of stainless steel, such as stainless steel sealing rings and stainless steel plate heat exchangers. (5) Some other exterior parts on stainless steel cars for car decoration not only have their own functions, but also have decoration functions. Such as stainless steel moldings, antennas, wheel covers, or handrails, safety railings, and booms of large passenger cars. With the continuous development of the automotive industry, stainless steel is more and more widely used in the automotive industry.
