Form This specification covers a corrosion and heat-resistant nickel alloy in the form of bars 3.00 inches (76.2 mm) and under in nominal diameter or least distance between parallel sides@ forgings@ flash welded rings 3.00 inches (76.2 mm) and under in nominal radial thickness@ and stock of any size for forging@ flash welded rings@ or heading (see 8.5). Application These products have been used typically for parts@ such as turbine rotors@ shafts@ bolts@ dowels@ and fittings@ requiring high strength up to 1600 ??(871 ?? after precipitation heat treatment and oxidation resistance up to 1800 ??(982 ??@ but usage is not limited to such applications. Classification Alloy supplied to this specification is classified as follows: Type 1 - Vacuum induction melted followed by vacuum arc consumable electrode remelting Type 2 - Vacuum induction melted followed by electroslag remelting. Unless a specific type is ordered@ either type may be supplied.
