Inconel 725

Inconel 725 is a corrosion-resistant nickel-chromium alloy with added molybdenum, niobium and titanium. It has good resistance to stress corrosion cracking, pitting corrosion and crevice corrosion in reducing and oxidizing environments. Inconel 725 can obtain extremely high strength through age hardening, reaching twice the strength of Inconel alloy 625 under annealing conditions, and has high ductility and toughness.Alloy 725 can be available in Bar, Pipe, Forging, Plate, Fasteners, Coil, Wire, Fitting, etc.

Overview of Inconel 725

Other common name: UNS N07725

Inconel Alloy 725 is a nickel-chromium alloy with addition of molybdenum, niobium and titanium. The high content of nickel and chromium ensures its corrosion resistance and stress corrosion cracking resistance in reducing and oxidizing environments. Titanium can inhibit intergranular corrosion. A large amount of molybdenum content enhances the resistance to reducing media and the ability to resist pitting and crevice corrosion. In addition, the combination of various elements makes the alloy provide excellent resistance to the conditions in sour oil and gas wells containing carbon dioxide, chloride and hydrogen sulfide. Inconel 725 can obtain extremely high strength through age hardening, reaching twice the strength of Inconel alloy 625 under annealing conditions. Inconel 725 was developed through heat treatment rather than cold working, so it retains high ductility and toughness. In addition, it is possible to impart strength to large or uneven parts that cannot be reinforced by cold working.

Features of Inconel 725

● Excellent corrosion resistance in various corrosive environments such as sea water and industrial acids

● Aging hardening can obtain extremely high strength

● Excellent ductility and toughness

● Outstanding resistance to stress corrosion cracking

Applications of Inconel 725

Inconel Alloy 725 can be widely used in various environments due to its high temperature resistance, corrosion resistance and high strength. These are just examples:

● Downhole equipment for highly corrosive and acid oil wells

● Oil and gas hangers, connectors

● Chemical process equipment

● Stirrer, valve stem, etc.

● Hangers, landing joints and high-strength fasteners in marine applications.

● Used as a hanger, fixed joint, side bag mandrel and polished hole container in acid gas service
