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.
Applications
Gas turbine engines, rocket motors, nuclear reactors and spacecraft.
