Form: This specification covers a corrosion and heat resistant nickel alloy in the form of welding wire. Application: Primarily for use as filler metal for gas-tungsten-arc or gas-metal-arc welding of parts fabricated from similar or dissimilar corrosion and heat resistant alloys not over 0.125 inch (3.18 mm) in nominal thickness@ requiring joints with strength and corrosion resistance comparable to those of the basis metal.
