HF 300B
Semi-hard machinable surfacing electrode
Description & applications
Basic coated electrode semi-hard, machinable and tough with approx. 120% recovery for surfacing on equipment parts and tools. Resisting to medium friction and compression - highly resistant to shocks - dense deposit and free of cracks. Soft fusion - low spatters - self releasing slag - nice aspect of the beads.
General applications: For heavy build up and as cushion layer on forging die cavities, mandrels, gear teeth, chains, sprockets, punches, blades, drawing dies.
