(AMS 5662)

Alloy 718 Tube (UNS N07718, W Nr 2.4668) is an austenitic nickel-based superalloy. Alloy 718 exhibits excellent high yield tensile and creep-rupture properties at temperatures up to 1300ºF and oxidation resistance to 1800ºF. Alloy 718 is used in applications that require high strength such as parts for jet engines and high speed airframe parts such as wheels, buckets, spacers and high temperature bolts and fasteners.

Availability

Alloy 718 is available in Tube Bar (Rounds, Flat, Shapes), Wire, Billet, Strip, Rod, Sheet, Plate. For all stock availability contact Sales.
