These products are celebrated for their impressive durability, heat resistance, and cost-effectiveness. Crafted from ferritic stainless steel, they’re built to perform reliably even in high-temperature environments and areas with moderate corrosion. Thanks to their excellent formability, weldability, and resistance to oxidation, Stainless Steel 409 Sheets and Plates have become a go-to choice for industries that need materials that last without breaking the bank. Lecong Stainless is committed to maintaining high-quality standards through advanced production facilities, catering to both local and international markets with precision-engineered solutions.
The composition of Stainless Steel 409 Sheets and Plates includes iron, chromium (10.5–11.75%), manganese, silicon, and a low carbon content, often with titanium added for stabilization. This blend enhances weldability and minimizes the risk of carbide precipitation while ensuring durability. Their mechanical properties boast a tensile strength of 380–450 MPa, a yield strength of around 170–240 MPa, and impressive elongation, which contributes to their excellent formability. The ferritic microstructure provides oxidation resistance at high temperatures, along with dimensional stability and toughness. These characteristics make Stainless Steel 409 Sheets and Plates a perfect mix of performance, affordability, and durability for a wide range of industrial applications.
