Description
Solid wire for Ni-Cr-Fe alloys
Consumable used for the overlay cladding of ferrous materials used in high temperature applications, and the welding of nickel-chromium-iron alloy to itself, and to steels, and for welding IN657. This product is enriched with Boron and Zirconium to minimize the tendency for ductility-dip cracking and oxide inclusions. Welds made with this composition are particularly resistant to high temperature oxidation, carburization, and sulfidation, as well as to reducing and metal dusting environments.
