Anucha Metals, a top-notch manufacturer and supplier located in Bangkok, Thailand, specializes in high-quality Stainless Steel 316 Flanges that are designed to offer outstanding corrosion resistance, strength, and durability. Crafted to meet international standards, these flanges are perfect for piping systems that come into contact with corrosive chemicals, saltwater, or high-moisture environments where long-lasting reliability is essential. Stainless Steel 316 is an austenitic stainless steel grade that’s enriched with molybdenum, giving it superior resistance to pitting, crevice corrosion, and chloride-induced damage compared to 304 stainless steel. Anucha Metals provides a diverse selection of Stainless Steel 316 Flanges in various types, pressure classes, sizes, and specifications, catering to industries such as marine, chemical processing, oil & gas, pharmaceuticals, and food & beverage.
These flanges 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 composition ensures excellent corrosion protection, high tensile strength, and remarkable durability in harsh and chloride-rich environments. The austenitic structure guarantees toughness across a broad temperature range, weldability, and compatibility with different piping systems, making these flanges suitable for both high-pressure and high-temperature applications.
