Alloy Bars and Forgings, Corrosion and Heat Resistant, 54ni 17.5cr 16.5co 4.0mo 2.9ti 2.9al 0.006b, Vacuum Melted, Solution Heat Treated(Cancelled Mar 1999)
This specification covers a corrosion and heat resistant nickel alloy in the form of bars, forgings, and stock for forging or heading. Primarily for parts, such as turbine blades, bolts, and fittings, requiring high strength up to 1600 degrees F (870 degrees Centigrade) and oxidation resistance up to 1800 degrees F (980 degrees C). This specification has been declared "Noncurrent" by the Aerospace materials Division, SAE, as of October 16, 1987. It is recommended, therefore, that this specification not be specified for new designs.
