HARD FACING ELECTRODE

DESCRIPTION

This is a chromium carbide hardfacing electrode for use in the downhand position only. The weld deposits are unmachinable but can be ground. The deposited metal is highly resistant to abrasive wear with moderate to high impact and is recommended for special hard facing applications on carbon steels, 14% manganese steels and cast iron. Can be used for hardfacing components subject to high temperature upto 600″ C

HARDNESS

58-64 HRc

APPLICATION

In sugar mills this can be used for the hard facing of cane knives fibrizor hammers shredder hammers, trash plates, scrapper plates, screw conveyor, arm grabs, excavator bucket lips and teeth and TRPF rollers. This electrode also has many applications in the Steel, Power, Cement, Paper and Mining Industries.

TECHNIQUE

All the above components can be hardfaced after removing the old weld deposit if any by grinding. The welding procedure should follow from top leading to end using criss cross welding pattern with maximum two layers to eliminate relief checks.

RECOMMENDED AMPERAGE

For 3.25 mm X 350 mm – 100 to 130 Amps

For 4.00 mm X 450 mm – 140 to 180 Amps
