Product Code:SAE AMS5706
Title:Nickel Alloy, Corrosion and Heat-Resistant, Bars, Forgings, and Rings, 57Ni - 19.5Cr - 13.5Co - 4.3Mo - 3.0Ti - 1.4Al - 0.006B - 0.05Zr, Consumable Electrode Or Vacuum Induction Melted, 1825 to 1900 掳F Solution Heat Treated
Issuing Committee:Ams F Corrosion Heat Resistant Alloys Committee
Scope:This specification covers a corrosion and heat-resistant nickel alloy in the form of bars, forgings, flash welded rings, and stock for forging, flash welded rings. These products have been used typically for parts, such as fasteners, flanges, and rings, requiring high strength up to 1500 掳F and oxidation resistance up to 1750 掳F (954 掳C), particularly those parts which are formed or welded and then heat treated to develop required properties, but usage is not limited to such applications.
