Inconel 725

Inconel 725 is a nickel-chromium-molybdenum-niobium alloy that is highly resistant to corrosion and is age hardenable for extremely high strength. It has essentially the same corrosion resistance as INCONEL alloy 625, which is widely used in a broad range of severely corrosive environments. The strength of age-hardened Alloy 725 is the twice that of annealed alloy 625, which is developed by heat treatment. 

Inconel 725 is used for hangers, landing nipples and high strength fasteners in marine applications.
