Nickel-based Alloy Flanges ASTM B564 Inconel 625 UNS N06625 Annealed Forging Flange
Inconel 625 is a high-strength, corrosion-resistant nickel-chromium-based superalloy. It is used for its high corrosion, oxidation resistance, and excellent strength at temperatures ranging from cryogenic to 1,800°F (982°C). Inconel 625 flanges are widely used in environments that require resistance to extreme conditions, such as seawater, acids, and high temperature.
Properties:
Excellent corrosion and oxidation resistance
High tensile and creep-rupture strength
Good fatigue and thermal-fatigue strength
Outstanding weldability and brazeability
Common Flange Types:
Weld neck flanges
Slip-on flanges
Threaded flanges
Lap joint flanges
Socket weld flanges
Blind flanges
