AMS 5589 specification covers a corrosion and heat resistant nickel alloy in the form of seamless tubing. AMS 5589-certified Inconel 718 tubes are critical in extreme environments, balancing strength, corrosion resistance, and thermal stability. Their use spans industries requiring reliability under stress, though cost and fabrication challenges necessitate careful application planning.
Inconel 718 (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.
