Anucha Metals, a reputable manufacturer and supplier located in Bangkok, Thailand, specializes in high-quality Stainless Steel 316 Nuts that are built for strength, corrosion resistance, and long-lasting durability. Crafted to meet international standards, these nuts are perfect for fastening applications in settings where they might encounter chemicals, moisture, or saltwater that could lead to corrosion. Stainless Steel 316 is an austenitic stainless steel grade that’s enhanced with molybdenum, giving it a significant edge in resisting pitting, crevice corrosion, and chloride-induced damage compared to 304-grade stainless steel. Anucha Metals offers a diverse selection of Stainless Steel 316 Nuts in various sizes and specifications, catering to the needs of industries such as marine, chemical, oil & gas, construction, and food processing.
These Stainless Steel 316 Nuts are primarily made up of iron, chromium (16–18%), nickel (10–14%), and molybdenum (2–3%), along with carefully controlled amounts of carbon, manganese, silicon, phosphorus, and sulfur. This specific chemical makeup ensures excellent protection against corrosion, high tensile strength, and good ductility, even in harsh, chloride-rich environments. The austenitic structure guarantees toughness across a wide temperature range, easy fabrication, and compatibility with different stainless steel grades in bolted assemblies, ensuring secure and dependable fastening.
