DAIKOWT 625W
GTAW
- NICKEL ALLOYS
625W
Description
Solid rod with nominal composition 64% Ni, 22% Cr and 9% Mo (Nb free)
The chemistry is very similar to ERNiCrMo-3 but Nb free. It ensures good resistance to hot cracking and a microstructure free of intermetallic phases (Niobium Nitride) with a very good toughness. The properties of this filler metal are suitable to weld superduplex and superaustenitic in low temperature applications with high impact toughness and cryogenic 9%Ni steels. Used for welding of Nickel-Chromium-Molybdenum alloys of similar composition as well as for cladding on low alloyed steels. Also suitable when component must be plastically deformed after welding.
