HF 50Co
Hardfacing Electrode - High Temperatures
Description & applications
The weld deposit resists against metal to metal wear , corrosion and high temperatures. Therefore the electrode is used for overlay and build up of machinery parts and tools subject to impact, compression and wear, used at operating temperatures up to 650° C. The deposit is resistant to thermal shock and can be machined with tungsten carbide tipped tools. Rutile-basic coated electrode with a stable arc, regular drop transfer and a smooth deposit.
General applications: For building up dies, for hot working tools , for moulds, continuous driving rolls, mandrels, forming tools, ...
Base materials: High strength carbon steels, tool steels and hot working steels

Application Instructions
Redrying 2h at 300°C, if necessary.Clean weld zone properly. Preheat massive work pieces to 150- 400°C, depending on the composition . Hold the electrode vertically with a short arc. Keep temperature during welding and let the work piece cool slowly.
