409L stainless steel factory direct sales

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

409L has low cost, good flexibility, high yield and easy replacement. It is a new environmentally friendly product.

409L stainless steel has excellent corrosion resistance and is suitable for extending the life of automobiles and reducing the weight of automobiles. As a recyclable and environmentally friendly material, GM, Ford, Volkswagen, DaimlerChrysler and other major automobile manufacturers use 100% stainless steel in exhaust systems. . The automobile exhaust system treats the high-temperature, high-speed combustion exhaust gas generated by the automobile engine and discharges it outside the automobile.

Recently, due to the increasingly stringent environmental protection standards for automobile exhaust, the increase in short-distance urban driving, and the distribution of snow removers in winter, the use standards of exhaust systems are also becoming more and more strict. Technical requirements, high-end motorcycle exhaust system has adopted 409L material. The amount of 409L stainless steel used in each vehicle is 35KGS-65KGS.

Stainless steel refers to steel that is resistant to weak corrosive media such as air, steam, and water, and chemically corrosive media such as acid, alkali, and salt, also known as stainless acid-resistant steel. In practical applications, the steel that is resistant to weak corrosive media is often called stainless steel, and the steel that is resistant to chemical media corrosion is called acid-resistant steel. Due to the difference in chemical composition between the two, the former is not necessarily resistant to chemical media corrosion, while the latter is generally stainless. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel.

Type

Stainless steel is often divided into: martensitic steel, ferritic steel, austenitic steel, etc. In addition, it can be divided into: chromium stainless steel, chromium-nickel stainless steel and chromium-manganese-nitrogen stainless steel according to the composition.
