Features

Inconel 718 is an age-hardenable nickel-chromium alloy that combines corrosion resistance with high strength and good fabricability. It has high creep-rupture strength at temperatures up to 700. Its excellent relaxation resistance contributes to its application in springs.

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 700 properties made it use in a wide range of high requirement environments.
