Stainless Steel 316 Flanges, manufactured and supplied by Adinox Overseas, are highly sought after across various industries due to their superior corrosion resistance, excellent mechanical strength, and outstanding durability. These flanges are made from austenitic stainless steel alloy containing molybdenum, which significantly enhances resistance to pitting and crevice corrosion in chloride environments. The presence of molybdenum differentiates Stainless Steel 316 Flanges from the standard 304 grade and makes them ideal for use in marine, chemical, and pharmaceutical industries.
The universal standard designation for these flanges is ASTM A182 F316, and the UNS number is UNS S31600. As per international standards, Stainless Steel 316 flanges are available in various types, including slip-on flanges, weld neck flanges, socket weld flanges, blind flanges, and threaded flanges, all precisely engineered to meet high-pressure and high-temperature service requirements. Adinox Overseas ensures that each flange adheres to global specifications including ANSI, ASME, DIN, BS, and EN standards.
Made with precision, ASTM A182 F316 flanges are suitable for use in pipelines, heat exchangers, reactors, and condensers. They are capable of withstanding temperatures ranging from cryogenic to elevated levels, making them versatile across numerous demanding sectors. The addition of nickel and chromium in the alloy further improves their oxidation resistance and makes them non-magnetic in the annealed condition. UNS S31600 flanges show excellent formability, weldability, and toughness even at sub-zero temperatures, which gives them an edge over other stainless steel grades.
With an expert engineering team and advanced infrastructure, Adinox Overseas ensures customization of SS 316 flanges in various sizes, pressure classes, and face types such as Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ) to meet client-specific project requirements. These flanges are widely used in oil and gas, petrochemical, food processing, marine, construction, pulp & paper, and water treatment industries.
