Inconel 725 Special Alloy UNS N07725 Alloy In Side Pocket Mandrels
Inconel 725 Special Alloy UNS N07725 Highly Resistant Alloy Used In Hangers, Landing Nipples, Side Pocket Mandrels
Product Description
INCONEL® alloy 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. Alloy 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.It has essentially the same corrosion resistance as INCONEL alloy 625, which is widely used in a broad range of severely corrosive environments.

Applications
The properties of INCONEL alloy 725 are useful for a range of applications that require outstanding corrosion resistance along with high strength. The alloy is used for hangers, landing nipples, side pocket mandrels and polished bore receptacles in sour gas service, where it resists the effects of hydrogen sulfide, chlorides and carbon dioxide. The alloy is also attractive for high strength fasteners in marine applications, where it resists corrosion, pitting and crevice attack in sea water.
