Inconel® 718

Inconel 718® is a precipitation-hardenable nickel-based alloy which displays properties including exceptionally high creep-rupture, tensile and yield properties at temperatures up to 1300°F. The nickel alloy works efficiently in low-temperature service.

Alloy 718 has excellent welding characteristics when compared to the nickel-base superalloys which have been hardened by aluminium and titanium. Jet engines, high-speed airframe parts such as wheels, buckets, spacers, and high-temperature bolts and fasteners, all utilise Inconel 718. Wellhead components in the oil & gas sector also employ this alloy.

The grade is resistant to corrosion, stress corrosion and fatigue, with good strength and ductility in sub-zero temperatures.
