Hard Facing Electrode
Product Code : HC440
Product Description
Hard Cover 440 (HC440) is a tubular, self-shielded wire for metal arc hard facing. It produces a low alloy steel weld deposit for heavy multi-layer build-up work on carbon steel parts. HC440 is used for rebuilding and resurfacing components subject to metal-metal wear and moderate abrasion. The weld deposit is machinable.
Typical Applications :
- Build-up of earthmoving equipment such as tractor rollers, idlers, chains and drive sprockets
- Excavator pads
- Electric shovel track carrier rolls
- Steel shafts
- Gears
- Crane wheels
- Steel mill rolls
- Mine car wheels
- Railcar couplings
