ATI Allegheny Ludlum AltempĀ® A286 Iron-Base Superalloy, UNS S66286
Categories: Metal; Ferrous Metal; Stainless Steel; Superalloy; Iron Base

Material Notes: Allegheny Ludlum Altemp A286 alloy is an iron-base superalloy useful for applications requiring high strength and corrosion resistance up to 704 degrees Celsius and for lower stress applications at high temperatures. Specific uses include jet engine nacelles, parts, and fasteners. Allegheny Ludlum Altemp A286 alloy is a heat and corrosion resistant austenitic iron-base material which can be age hardened o 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 -196 degrees Celsius. The alloy may be used for moderate corrosion applications in aqueous solutions. This 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.
