Adinox Overseas is a reputed manufacturer and exporter of high-quality Stainless Steel 321 Flanges, widely used in high-temperature and corrosive industrial applications. These flanges are fabricated in accordance with ASTM A182 F321 specifications and designated under the UNS S32100 standard. Stainless Steel 321 is a titanium-stabilized austenitic alloy that provides exceptional resistance to intergranular corrosion after exposure to high temperatures. This alloy is a perfect choice for flanged connections used in thermal, petrochemical, and aerospace applications where durability, temperature tolerance, and corrosion resistance are critical.

At Adinox Overseas, we deliver SS 321 flanges that exhibit excellent mechanical properties even at elevated temperatures. The titanium addition in grade 321 effectively stabilizes the structure against chromium carbide precipitation, enhancing the material’s resistance to oxidation and scaling. These characteristics make our flanges ideal for use in heat exchangers, refinery equipment, aircraft exhaust systems, expansion joints, and high-pressure piping systems. The material can withstand service temperatures up to 900°C (1652°F), making it suitable for thermal cycling environments.
