TECHNICAL DATA SHEET
Alloy 286
(UNS S66286) STEEL ALLOY
Chemical Composition Chemical Composition (wt%) limits as specified in ASTM A638 and ASME SA638*
Description
A-286 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. A-286 alloy is typically 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.
Data are typical, are provided for informational purposes, and should not be construed as maximum or minimum values for specification or for final design, or for a particular use or application. The data may be revised anytime without notice. We make no representation or warranty as to its accuracy and assume no duty to update.
