Form: 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@ or heading. Application: These products have been used typically for parts requiring high resistance to creep and stress-rupture up to 1300 ??(704 ?? and oxidation resistance up to 1800 ??(982 ??@ particularly those parts which are formed or welded and then precipitation heat treated to develop required properties@ but usage is not limited to such applications.
