Cored wire for hardfacing parts that have to resist severe abrasion in combination with high impact loads.
The combination of the tough matrix and the very hard Niobium carbides gives an abrasion resistant deposit that can withstand shocks.
The absence of slag allows welding in several layers without the elimination of slag.
Three layers can be built up without cracking.
Crusher cylinders, crusher hammers, bucket teeth and lips, sandpumps, impellers and screws.
Cane shredders and knives.
Knives and mixers in the pulp and paper industry.
Hardness: 56 - 64 HRC (is obtained from the first layer).
Open arc welding (no shielding gas required).
Stick-out: 30 - 40 mm (1.2"-1.6").
Remove all worn out material.
Preheat high carbon and low alloyed steels.
On steels with bad weldability, it is advisable to apply a base layer with Lastifil 8071 in order to avoid cracking.
