Hard surfacing electrode for high abrasion coupled with medium to heavy impact
General purpose surfacing alloy for surfaces subjected to abrasive wear and impact. The deposits are crack resistant but can be forged. Heavy build-ups are possible without the need for softer cushion layers. Excellent for out of position welding applications.
Applications
Build up and surfacing of new and worn machine parts of steel, cast steel, manganese steel, and cast iron. Also dredger teeth, crusher jaws, hammer mill parts, conveyors, drives, and earth borers. Used in agricultural, construction, and mining industries.
Procedure
Remove all foreign material from weld area. Preheat is not necessary. Maintain a medium arc length making either stringer beads or weave beads. Allow parts to cool slowly.
