409L stainless steel has strong resistance to corrosion, high temperature and fatigue, which can realize the life and light weight of exhaust system components.
409L has strong high temperature resistance, can realize high-efficiency engine and exhaust system, and reduce the thickness of exhaust system, which can reduce exhaust gas emissions.
409L is a new product with low cost, good flexibility, high yield rate and easy replacement. It is an environmentally friendly new product.
409L stainless steel has excellent corrosion resistance and is suitable for prolonging the life of automobiles and reducing the weight of automobiles. As an environmentally friendly material that can be recycled and reused, major automobile manufacturers such as GM, Ford, Volkswagen, DaimlerChrysler and other major automobile manufacturers use stainless steel in their exhaust systems. . The automobile exhaust system treats 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 after reburning the exhaust gas, it is converted into clean gas. Automobile exhaust system is the longest part of automobile components. The system has to withstand extreme temperature changes (-20～850℃) and high-frequency vibration of high-temperature and high-speed exhaust gas, and it is in the car with the largest changes and the most complex In the environment, the temperature limit that 409L can withstand is (-20～650℃). Recently, due to the increasingly stringent environmental protection standards for automobile exhaust, the increase in short-distance urban driving, and the spread of snow removers in winter, the exhaust system usage standards have also become stricter. From the European II-Euro IV standards, traditional steel materials cannot meet the requirements. Technical requirements, high-end motorcycle exhaust system has adopted 409L material.
