Form This specification covers a nickel alloy in the form of wire@ rod@ strip@ foil@ and powder and a viscous mixture (paste) of the powder in a suitable binder. Application This filler metal has been used typically for joining corrosion and heat-resistant steels and alloys requiring corrosion and oxidation resistant joints with good strength at elevated temperatures@ but usage is not limited to such applications. Also may be used as a corrosion and oxidation resistant hard coating.
