Anucha Metals, a top-notch manufacturer and supplier located in Bangkok, Thailand, specializes in high-quality Stainless Steel 409 Fasteners designed for durability, heat resistance, and reliable performance. Crafted to meet international standards, these fasteners are perfect for applications that require both strength and moderate corrosion resistance. Stainless Steel 409 is a ferritic stainless steel grade known for its good oxidation resistance and excellent weldability, making it a great fit for environments that experience heat and mild corrosive conditions. Anucha Metals offers a diverse selection of Stainless Steel 409 Fasteners in various sizes and types, catering to industries like automotive, petrochemical, power generation, marine, and construction with dependable fastening solutions.
These fasteners mainly consist of iron and chromium (10.5–11.75%), along with controlled amounts of carbon, manganese, silicon, phosphorus, sulfur, and often titanium to enhance stability. This specific composition strikes a balance between oxidation resistance, weldability, and cost-effectiveness while ensuring strength at higher temperatures. While they may not be as corrosion-resistant as some higher-grade stainless steels, 409 provides sufficient protection in mild atmospheric and exhaust-related environments, making it a practical and budget-friendly option for heat-intensive applications.
