AMS 5589 / Alloy 718 Seamless Tube Factory Price| ZYTC Alloy – ISO 9001 & AS 9120B Certified Supplier
AMS 5589 specification covers a corrosion- and heat-resistant nickel alloy in the form of seamless tubing 0.125 inch (3.18 mm) and over in nominal OD with nominal wall thickness 0.015 inch (0.38 mm) and over.
Alloy 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 1300°F (704°C) and oxidation resistance to 1800°F (982°C). Alloy 718 is used in applications that require high strength, such as parts for jet engines and high-speed airframe parts including wheels, buckets, spacers, and high-temperature bolts and fasteners.
ZYTC Alloy is an ISO 9001 and AS 9120B certified superalloy manufacturer and supplier, offering AMS 5589 Alloy 718 seamless tubing at factory-direct prices with precision tolerances, full material traceability, and fast global delivery.
