Hardfacing Welding Electrode
Standard: DIN 8555 (E6-UM-60)
Type No.: TY-C DUR 600
Specification & Application:
· Basic coated SMAW electrode for hard surfacing.
· Excellent resistance against compression stresses and impacts.
· 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, bucket knives, crusher jaws and cones, mill hammers etc.
