NiFe 55

Category: GMAW-GTAW Solid wires

Type: Nickel iron MIG wire for joining dissimilar materials and cast iron.

 

Properties:
Nickel Iron based filler metal for joint welding and claddings on cast Iron. Very wel suited also for
dissimilar welding between cast iron and high alloyed stainless and heat resistant steels or mild
steels. Excellent Weldabillity with extreme crack resistance with a ductile weld deposit. Good welding
and wetting characteristics and high resistance against porosity. The weld metal is corrosion and
heat resistant. Very well suitable for welding with robotics or automated processes.

 

Applications:
Suitable for welding stainless steels containing 12-14 Cr. Also for welding mild and low alloy steels
which are exposed to termperatures up to 450C. Cast Iron repairs, rebuilding shafts, wheels, spherical flange pipe fittings, critical joints between steel and cast iron etc.
