High Nickel Alloy Flanges such as Inconel and Incoloy Flanges are specifically designed for extreme temperature, high pressure, and highly corrosive service conditions. These nickel-based alloys provide excellent resistance to oxidation, carburization, thermal fatigue, and stress corrosion cracking.
High Nickel Alloy Flanges are widely used in critical piping systems across aerospace, chemical processing, oil & gas, power generation, nuclear plants, heat exchangers, and furnace equipment where long service life and reliability are essential.
High Nickel Alloy Flanges are available in a wide range of Inconel and Incoloy grades to suit demanding industrial applications. Commonly supplied grades include Inconel 600, 625, 718 and Incoloy 800, 800H, 825, offering superior mechanical strength, high-temperature stability, and outstanding corrosion resistance.
