Inconel 718
Inconel 718
Description: Inconel 718 / N07718 / GH4169 / 2.4668
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.
