Best Quality and Price 409L Stainless Steel Tube


409L high temperature resistance, can achieve high efficiency of the engine and exhaust system, and reduce the exhaust system thickness, can reduce exhaust emissions.


Low cost, good flexibility, high rate of finished products, easy to replace, belongs to the environmental protection of new products.


With excellent corrosion resistance, 409L stainless steel is suitable for extending car life and lightweight cars, and as a recyclable environmental protection material, GM, Ford, Volkswagen, DaimlerChrysler and other major automobile manufacturers use 100% stainless steel in their exhaust systems. The automobile exhaust system will be produced by the automobile engine high temperature, high speed combustion exhaust gas treatment, it out of the car. The main function of the exhaust system is to reduce vibration and noise, and to convert the exhaust into a clean gas after reburning. The automobile exhaust system is the longest part of the automobile parts. The system is able to withstand great temperature changes (-20 ~ 850℃) and high-frequency vibration of high temperature and high speed exhaust gases. Moreover, it is in the most varied and complex environment in the automobile. Recently, due to the increasingly strict environmental protection of automobile exhaust standard, short distance urban driving increases, partly due to the spread of winter snow removal agent, exhaust system using standard is strict, from the Ⅳ Ⅱ - Europe standard, the traditional steel can meet the technical requirements, high-end motorcycle exhaust system has been adopted 409 l material. The amount of 409L stainless steel used per vehicle is 35kgs-65kgs
