JIANGSU STEEL GROUP Inquiries :
Inconel 718 is a precipitation hardenable nickel-based alloy designed to display exceptionally high yield, tensile and creep-rupture properties at temperatures up to 1300F (704C). The age-hardening response of Inconel 718 permits annealing and welding without spontaneous hardening during heating and cooling. Nickel Alloy 718 has excellent weldability when compared to the nickel-base super alloys hardened by aluminum and titanium. Nickel Alloy 718 is used in aircraft engine parts and high-speed airframe parts such as wheels, buckets, spacers, and high temperature bolts and fasteners.
Nickel alloy Inconel 718® is usually provided in the solution annealed condition (AMS 5662 & AMS 5596), but can be also be supplied in the aged hardened or precipitation heat treated condition (AMS 5663 & AMS 5597) prior to forming.
