It is used for joining nickel base alloys to themselves and to stainless steels, carbon steels and Monel alloys. The high Ti content provides excellent porosity resistance in field welding applications. Typical applications include desalination plants, piping, furnace equipment and petrochemical and power generation plants. It is also used for surfacing carbon steels. It provides high strength and corrosion resistance at temperatures ranging from the cryogenic region to over 980°C. Weld deposits can be age hardened for greater strength at temperatures to about 700°C.
Nominal composition (wt. %) of this classification is 71 Ni, 16 Cr, 6 Fe, 3 Ti,
and 2.5 Mn.
Fully austenitic microstructure with Ti-rich carbides.
