Good corrosion Inconel 718 UNS NO7718 nickel-chromium-iron alloy

Inconel 718 Physical properties

Inconel 718 Alloy minimum mechanical properties in the roomtemperature

718 Characteristic as below:1.workability
2.High tensile strength,endurance strength,creep strength and rupture strength at 700ºC.
3.High inoxidability at1000ºC. 4.Steady mechanical performance in the low temperature.
5.Good welding performance.

Inconel 718 Metallurgical structure
718 alloy 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.

Inconel 718 Corrosion resistance
718 alloy with extremely resistance to stress corrosion cracking and pitting ability in high temperature or low temperature environments, especially the inoxidability in the high temperature.


Inconel 718 Application field:The elevated temperature strength, excellent corrosion resistance and workability at 700ºC properties made it use in a wide range of high requirement environments. 1.Steam turbine 2.Liquid-fuel rocket 3.Cryogenic engineering
4.Acid environment
5.Nuclear engineering
