Incoloy 825 Flanges

Incoloy 825 Flanges are essential pipe fittings, manufactured by Zeron Fastners, used to connect piping components, valves, and equipment to create a robust and serviceable piping system. These flanges are forged from the high-performance alloy Incoloy 825 (UNS N08825), a complex alloy containing nickel, chromium, iron, molybdenum, and copper. This composition provides exceptional resistance to a wide range of corrosive attacks, including immunity to stress-corrosion cracking in chloride-bearing environments and superior defense against reducing acids like sulfuric and phosphoric acid. Zeron Fastners offers these flanges in all standard types, such as Weld Neck, Slip-On, Blind, and Socket Weld, making them indispensable for critical, high-temperature, and highly corrosive piping systems in chemical processing, nuclear power, and oil and gas industries.
