NiFe 55

type 
Nickel iron MIG wire for joining dissimilar materials and cast iron.
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, critical joints between steel and cast iron etc.
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.
