    718 Characteristic as below:
    1.workability
    2.High tensile strength,endurance strength,creep strength and rupture strength at 700°C. 
    3.High inoxidability at1000°C.
    4.Steady mechanical performance in the low temperature.
    5.Good welding performance.

    Inconel 718 Metallurgical structure 
    718alloy 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 700°C 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
