Inconel 725
Inconel 725 (UNS N07725) is a nickel-chromium-molybdenum-niobium alloy that is highly resistant to corrosion and has been age hardened for extremely high strength twice that of annealed alloy 625. Inconel 725 strength is developed by heat treatment rather than by cold work this also enables strength to be imparted to large non-uniform sections that cannot be strengthened by cold works. Inconel 725 is used for hangers, landing nipples and high strength fasteners in marine applications.

Inconel 725 Characteristic as below:

A nickel-chromium-molybdenum-niobium alloy that is highly resistant to corrosion and is age hardenable for extremely high strength. The strength of this alloy is developed by heat treatment to achieve high ductility and toughness. The alloy is resistant to hydrogen embrittlement and stress-corrosion cracking.

Inconel 725 Application field :

Used for hangers, landing nipples, side pocket mandrels and polished bore receptacles in sour gas service. Also used for high-strength fasteners in marine applications.
