Inconel® 718 is a precipitation-hardening nickel-chromium alloy with a high strength and good ductility up to 1300°F (704°C). this Alloy containing significant amounts of iron, columbium, and molybdenum, along with lesser amounts of aluminum and titanium.Nickel 718 also has relatively good weldability, formability, and excellent cryogenic properties compared to other precipitation hardening nickel alloys. The sluggish precipitation hardening response of this alloy allows it to be readily welded without hardening or cracking. Alloy 718 is non-magnetic. It maintains good corrosion resistance and oxidation resistance and is used for parts requiring high resistance to creep and stress rupture up to 1300°F (704°C) and oxidation resistance up to 1800°F (982°C).

Inconel 718 is Austenitic structure, precipitation hardening generate “γ” made it excellent mechanical performance. G rain boundary generate “δ” made it the best plasticity in the heat treatment.with extremely resistance to stress corrosion cracking and pitting ability in high temperature or low temperature environments, especially the inoxidability in the high temperature.
1.workability
2.High tensile strength,endurance strength,creep strength and rupture strength at 700℃.
3.High inoxidability at1000℃.
4.Steady mechanical performance in the low temperature.
The elevated temperature strength, excellent corrosion resistance and workability at 700℃ properties made it use in a wide range of high requirement environments.Inconel grades are fit for use in the production of components that are employed in the severe environments such as turbocharger rotors & seals, motor shafts for electric submersible well pump, steam generators, tubes for heat exchangers, firearm sound suppressor blast baffles and in machine guns, black box recorders in aeroplanes etc.
