Alloy A286 Nickel Sheet, Coil & Bar - AMS 5525, 5858, 5731, 5732, 5737
Incoloy Alloy® A286 is an iron-based superalloy useful for applications requiring high strength and corrosion resistance up to 1300˚F (704˚C) and for lower stress applications at higher temperatures. The mechanical properties of this alloy are developed by suitable solution annealing and precipitation hardening treatments. Alloy A286 is non-magnetic. This alloy has good oxidation resistance and is designed to maximize creep and stress rupture properties, with some reduction in strength. A-286 can attain high strength levels when aged after cold work, and has wide application as high temperature fasteners and springs.

Resistance to Corrosion and Oxidation
Type A286 alloy content is similar in chromium, nickel, and molybdenum to some of the austenitic stainless steels. Consequently, this alloy possesses a level of aqueous corrosion resistance comparable to that of the austenitic stainless steels. In elevated temperature service, the level of corrosion resistance to atmospheres such as those encountered in jet engine applications is excellent to at least 1300°F (704°C). Oxidation resistance is high for continuous service up to 1500°F (816°C) and intermittent service up to 1800°F (982°C).
