409L SS Pipe Tube

409L has strong high temperature resistance, can achieve high-efficiency engines and exhaust systems, and reduce the thickness of the exhaust system, which can reduce exhaust emissions.
409L has low cost, good flexibility, high yield rate, and is easy to replace. It is an environmentally friendly new product.
409L stainless steel has excellent corrosion resistance and is suitable for extending the life of the car and reducing the weight of the car. As a recyclable and environmentally friendly material, major automobile manufacturers such as GM, Ford, Volkswagen, DaimlerChrysler and other major automobile manufacturers use 100% stainless steel in their exhaust systems. . The automobile exhaust system processes the high-temperature, high-speed combustion exhaust gas generated by the automobile engine and discharges it to the outside of the automobile. The main function of the exhaust system is to reduce vibration and noise, and to convert the exhaust gas into clean gas after reburning it. The automobile exhaust system is the longest component in the automobile. This system has to withstand great temperature changes (-20 ~ 850°C) and high-frequency vibrations of high-temperature and high-speed exhaust gases. It is also the largest and most complex place in the car. In the environment, the temperature limit that 409L can withstand is (-20~650℃). Recently, due to increasingly stringent environmental protection standards for automobile exhaust, the increase in short-distance urban driving, and the spread of snow removal agents in winter, the use standards of exhaust systems have also become increasingly strict. From Euro II to Euro IV standards, traditional steel cannot meet their requirements. Due to technical requirements, high-end motorcycle exhaust systems already use 409L materials. The amount of 409L stainless steel used in each vehicle is 35KGS-65KGS.
