Anucha Metals, a top-notch manufacturer and supplier located in Bangkok, Thailand, specializes in high-quality Stainless Steel 405 Nuts that are perfect for reliable fastening in both industrial and mechanical settings. Crafted to meet international standards, these nuts boast impressive strength, durability, and resistance to scaling even at high temperatures. Stainless Steel 405 is a ferritic stainless steel grade that’s stabilized with aluminum, enhancing its oxidation resistance and preventing hardening after welding. This makes it a great choice for applications that need thermal stability and moderate corrosion resistance. Anucha Metals provides Stainless Steel 405 Nuts in a variety of sizes and specifications, catering to industries like petrochemical, automotive, marine, power generation, and general engineering.
These Stainless Steel 405 Nuts are primarily made up of iron and chromium (11.5–14.5%), along with trace amounts of carbon, manganese, silicon, phosphorus, sulfur, and aluminum for stabilization. This unique composition boosts oxidation resistance, keeps toughness intact, and helps avoid embrittlement during thermal cycling or welding. Although they can’t be hardened through heat treatment, these nuts still deliver solid mechanical strength, dimensional stability, and corrosion resistance in mildly corrosive environments. Their ferritic microstructure enhances thermal conductivity and helps resist stress corrosion cracking, making them reliable for both static and dynamic fastening applications.
