Lecong Stainless stands out as a top manufacturer and supplier based in Da Nang, Vietnam, specializing in high-quality Stainless Steel 409 Coils. These coils are celebrated for their durability, heat resistance, and affordability. Stainless Steel 409, a ferritic grade, is highly regarded for its impressive corrosion resistance, excellent oxidation resistance at high temperatures, and outstanding weldability. Crafted with precision to meet international standards, these coils are perfect for industries that demand long-lasting material performance. With state-of-the-art production facilities and rigorous quality checks, Lecong Stainless delivers Stainless Steel 409 Coils that are reliable and consistent for both local and global markets.
The composition of Stainless Steel 409 Coils includes iron, chromium (10.5–11.75%), low carbon, manganese, and silicon, with titanium often added for stabilization. This blend enhances weldability, toughness, and oxidation resistance. The mechanical properties feature a tensile strength of 380–450 MPa, yield strength of 170–240 MPa, and good elongation, ensuring excellent formability. Thanks to their ferritic structure, these coils offer dimensional stability, durability, and moderate corrosion resistance. While they may not match the corrosion resistance of austenitic stainless steels, Stainless Steel 409 Coils strike a cost-effective balance of strength, heat resistance, and economy, making them ideal for a variety of applications.
