Materiali di consumo omologhi alla lega base 625 (Ni-21%Cr-9Mo-
Consumables matching the Ni base 625 alloy (Ni-21%Cr-9Mo-
3,5%Nb), used for the high temperature strength, structural
stability and good resistance to corrosion
Consumables designed for joining pure nickel and for surfacing of
steel. They are suitable for dissimilar welding of pure nickel to stainless
steels, carbon steels, nickel alloys, monel 400 and cupronickel.
Alloy 657 has exceptional resistance to hot corrosion (800-950°C). The nominal composition (wt %) of filler metal of this classification is 55 Ni, 44 Cr.
Consumables for welding Hastelloy® X base metal and dissimilar
welding of this alloy to nickel base alloys, stainless, carbon and low
alloy steels. Outstanding strenght and oxidation resistance up to
1200°C. Also suitable for overlay cladding.
