ATI A286™ alloy (UNS S66286) is a Ni-Cr austenitic precipitation-hardened iron-based steel that is one of the original superalloys. It has been used for applications requiring high strength and corrosion resistance up to 1,300°F (704°C), and for cryogenic applications. Its relatively low alloy content and low-cost formulation make it an excellent choice for many applications. ATI A286™ alloy is produced by vacuum induction melting (VIM), followed by vacuum arc (VAR) or electroslag (ESR) remelting. Applications include jet engine, supercharger, and missile components including: wheels and blades, casings, afterburner and sound suppressor parts, fuel nozzles, fasteners, extrusion tooling and miscellaneous hardware This alloy is designated Grade or Type 660 in several specifications.
