Advantage

409L has strong high-temperature resistance, which can achieve efficient engine and exhaust system, reduce the thickness of the exhaust system, and reduce exhaust emissions.
409L has low cost, good flexibility, high yield, and is easy to replace, making it an environmentally friendly new product.
409L stainless steel has excellent corrosion resistance and is suitable for extending the lifespan and lightweight of automobiles. As a recyclable and environmentally friendly material, major automobile manufacturers such as GM, Ford, Volkswagen, DaimlerChrysler, etc. use stainless steel 100% in their exhaust systems.

Product Details

Stainless steel is often divided into: Martensite steel, ferrite 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 their composition.
1. Ferritic stainless steel: containing 12% to 30% chromium. Its corrosion resistance, toughness, and weldability increase with the increase of chromium content, and its resistance to chloride stress corrosion is superior to other types of stainless steel.
2. Austenitic stainless steel: contains more than 18% chromium, as well as about 8% nickel and a small amount of elements such as molybdenum, titanium, and nitrogen. Good comprehensive performance and resistance to corrosion in various media.
3. Austenitic ferrite duplex stainless steel: It combines the advantages of both austenite and ferrite stainless steel, and has superplasticity. Stainless steel with austenite and ferrite structures accounting for about half each.
4. Martensitic stainless steel: It has high strength but poor plasticity and weldability. Common brands of Martensitic stainless steel include 1Cr13, 3Cr13, etc. Because of its high carbon content, it has high strength, hardness and wear resistance, but its corrosion resistance is slightly poor. It is used on some parts with high mechanical performance requirements and general corrosion resistance requirements, such as springs, turbine blades, hydraulic valves, etc. This type of steel is used after quenching and tempering treatment.
