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.
