GMAW-GTAW Solid wires
Nickel based filler metal against extreme temperature conditions.
Nicro FM 53MD is used for the gas-tungsten-arc and gas-metal-arc welding of INCONEL alloy 693, and the overlaying of carbon steels and stainless steels to provide a nickel-chromium-aluminum alloy corrosion resistant surface.
Excellent welding properties with high build-up capacity and low dilution rate. Excellent resistance against temperature cycling conditions exeeding 1200°C and carburized medias. Excellent fatique strenght and creep properties. The high chromium and aluminum levels provide excellent resistance to metal dusting in chemical and petrochemical applications. The product also provides excellent resistance to carburization, sulfidation, and other high temperature corrosion forms Welding similar alloys that have to resist extreme high temperature and for cladding steels or stainless steels to obtain a high temperature resistant surface against oxidation.
