Ni-Cr Filler Metal
INCONEL Filler Metal 72M is used for the overlay cladding of ferrous materials used in high temperature applications, and the welding of nickel-chromium-iron alloy (ASTM B163, B166, B167, and B168 having UNS number N06690) to itself , and to steels, and for welding IN657 and INCO clad 671/800H, using the GTAW, GMAW, and PAW processes. Welds made with this composition are particularly resistant to high temperature oxidation, carburization,
and sulfidation, and to reducing-sulfidizing and metal dusting environments.
