A 5.9kg packet of 4.0mm E 6-UM-60 hardfacing electrodes from UTP. They are universally applicable for cladding on parts of steel, cast steel and high Mn-steel, subject simultaneously to abrasion, impact and compression. Typical application fields are the earth moving and stone treatment industry, e.g. excavator teeth, bucker knives, crusher jaws and cones, mill hammers etc., but also for cutting edges on cold cutting tools. The deposit is machinable by grinding only.

Hardness of pure weld deposit: 56 â€“ 58 HCR
After soft-annealing 780 -820Â°C / oven: approx. 25 HRC
After hardening 1000 â€“ 1050Â°C / oil: approx. 60 HRC
1 layer on high Mn-steel: approx. 22 HRC
2 layers on high Mn-steel: approx. 40 HRC

Welding instruction:
Hold electrode as vertically as possible and with a short arc. Preheat heavy parts and high-tensile steels to 200- 300Â°C. On high Mn-steel, cold welding (max. 250Â°C) is recommended, if necessary, intermediate cooling. On parts tending to hardening cracks, a cushion layer with UTP 630 is welded. UTP 630 should also be used for welding cracks under hardfacings. If more than 3 â€“ 4 layers are needed, apply the softer electrodes UTP DUR 250 or UTP DUR 300 for build-up. Re-dry electrodes that have got damp for 2h / 300Â°C.
