INCONEL® Filler Metal 72M
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-selfidizing and metal dusting environments.
