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
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 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
