Features:
UNS Number N07718
Inconel 718 is an age-hardenable nickel-chromium alloy that combines corrosion resistance with high strength and good fabricability. It has a high creep-rupture strength at temperatures up to 700℃. Its excellent relaxation resistance contributes to its application in springs.
Applications:
Inconel 718 is applied in Gas turbine engines, rocket motors, nuclear reactors and spacecraft, etc.
