Description
Hardfacing Electrode HF-400 x 4 mm – 6.5 Kg
Features
- 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.
All weld metal Hardness
~ 400HB/ 39 – 42HRC
Typical weld metal composition (%)
- C: 0.30
- SI: 0.5
- Cr: 1.0
- Mn: 1.5
- Fe: Rem

Additional information
Redrying, if necessary, 1h/150 degC. 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 degC, depending on their composition and thickness.
Slow cooling in air after surfacing.
