Alloys for Wearfacing
The general term hardfacing means to put a
protective layer of material on a surface to prolong the life of the
part. A more
appropriate word to use for this activity is wearfacing. To
effectively wearface a part and extend its life, a basic understanding
of hardness, types of base metals used in wearfacing, types of wear, and
types of filler alloys is needed.
Hard surfacing electrode for corrosion resistance at elevated temperatures.
Cobalt based product produces a flat weld with high deposition.
Deposits are highly resistant to moderate impact, abrasion, erosion, and corrosion at elevated temps.
For use such as: hot trimming dies, punches, slide valve gates and discharge valves.
Medium hardness build-up alloy for most steels.
Economical, general purpose alloy providing high compression strength and impact wear, with moderate abrasion resistance.
Ideal as a buffer layer for harder overlays.
Deposits are machinable and can be forged.
Oxy-acetylene torch cuttable deposits.
For uses such as: rope winches, truck wheels, roll ends, tractor pads, couplings and brake drums.
