Alloy A-286 nickel is an iron-based super alloy useful for applications requiring high strength and corrosion resistance up to 1300 degrees Fahrenheit and for lower stress applications at higher temperatures. A-286 can be hardened to a strength level. The alloy is also useful for low temperature applications requiring a ductile, non-magnetic high strength material at temperatures ranging from above room temperature down to at least -320 degrees Fahrenheit. This alloy can also be used for moderately corrosive applications in aqueous solutions. All of our A-286 is ordered to specific decimal thicknesses. See the list to the left for thickness ranges.

Iron-Base Superalloy

Type A286 (UNS Designation S66286)

General Properties

Type A286 alloy (S66286) is an iron-base superalloy useful for applications requiring high strength and corrosion resistance up to 1300°F (704°C) and for lower stress applications at higher temperatures.

Type A286 alloy is a heat and corrosion resistant austenitic ironbase material which can be age hardened to a high strength level. The alloy is also used for low temperature applications requiring a ductile, non-magnetic high strength material at temperatures ranging from above room temperature down to at least -320°F (-196°C). The alloy may be used for moderate corrosion applications in aqueous solutions.

Type A286 alloy can be produced by AOD refining or vacuum induction melting. Vacuum arc or electroslag remelting procedures may be used to further refine the material. Type A286 alloy is available in plate, sheet and strip.

Resistance to Corrosion and Oxidation

Type A286 alloy content is similar in chromium, nickel, and molybdenum to some of the austenitic stainless steels. Consequently, A286 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).
