Product Description

HF-400 x 4.0mm

Wear facing electrode for impact resistance.

  • Tip colour : Light green
  • Classification  DIN 8555 : E1-UM-400
  • Rutile coated electrode for surfacing of machine and construction parts, as well as of tools made of  low-alloyed and cast steels which are subject to wear by pressure and impact.
  • Electrodes are easy to weld even on low amperage and small portable welding equipment with a low open arc voltage.
  • Soft flow with almost no spatter, self releasing slag, excellent weld bead appearance.
  • Sound, crack free deposit, machinable with carbide cutting tools.

General applications

Surfacing of rollers, gear teeth, stamps, hammers,  guide rails etc.

Additional information

Redrying, if necessary, 1h/150°C. Preheating is not required on mild and medium carbon steels. Low alloyed, high carbon tool steels etc. should be preheated, where possible, to 250 – 400°C, depending on their composition and thickness. Slow cooling in air after surfacing.
