A high-molybdenum, nitrogen-enriched, nickel-based filler metal was developed for welding superaustenitic stainless steels. The beneficial effects of high Ni content and nitrogen addition in reducing the solute microsegregation and the precipitation of intermetallic phases were used to design the filler alloy. The weld had a precipitate-free, fully austenitic microstructure and exhibited excellent mechanical properties, and reduced hot-cracking susceptibility and high-chloride pitting-corrosion resistance.
