Welding Alloys HARDFACE HC-O is a cored – self-shielded wire manufactured from high grade ferro-alloy additives providing a rich balance and blend of M7C3 carbide fractions.

The weld deposit contains chromium-rich primary carbides in a carbide-martensite eutectic matrix.

Offering increased abrasion resistance over traditional chromium carbide formulations suitable for hardfacing components subject to extremely severe abrasive wear and moderate impact.

Post weld relief checking is normal. Best limited to two (2) layers maximum.

Gas shielding is not required, torch electrode positive polarity (DCEP).

Applications:

Hardface HC-O is used for hardfacing components undergoing wear by earth, sand and abrasives.

Examples are Gyratory crusher cones and mantles, catalyst pipes and valves, slurry pipes and valve bodies, dredge pump bodies, sand dredge parts, extruder screws, “barmac” crushers, mining and earthmoving equipment, blast furnace bells, brick muller tyres, sugar mill crusher hammers, drag line components, coal pulverisor rolls, coke hammers, cone knives and shredders. Relief checking is normal and best limited to two layers unless impact loading is small.
