Anucha Metals, a well-respected manufacturer and supplier located in Bangkok, Thailand, specializes in high-quality Stainless Steel 409 Sheets and Plates that are built to last, resist heat, and offer great value for money. These products are crafted to meet international standards and are commonly used in settings that require moderate corrosion resistance and outstanding oxidation stability. Stainless Steel 409 is a ferritic stainless steel grade that boasts excellent weldability, thermal stability, and the ability to withstand scaling at high temperatures, making it a fantastic option for automotive, petrochemical, and industrial uses. Anucha Metals offers these Stainless Steel 409 Sheets and Plates in a range of thicknesses, sizes, and specifications to meet various project needs.
The composition of Stainless Steel 409 Sheets and Plates primarily includes iron and chromium (10.5–11.75%), along with carefully controlled amounts of carbon, manganese, silicon, phosphorus, sulfur, and often titanium to enhance stability. This well-balanced mix ensures improved oxidation resistance, solid mechanical strength, and structural stability during thermal cycling. While it may not resist corrosion as well as higher-chromium stainless steels, it performs reliably in mild atmospheric and exhaust-related environments, striking a practical balance between cost, strength, and heat resistance.
