Description
CARBO DURIT S 70 E – 5 mm
Standards DIN 8555 E21-UM-65-G
Characteristics
CARBO DURIT S 70 E a hard metal electrode with a sintered tungsten carbide core with an addition of Cr and Nb carbides and a coating for the Manual Metal Arc welding process.
It is specifically designed for hardfacing of parts exposed to extreme abrasion.
Typical applications
It is highly recommended for applications where extreme abrasion by minerals with little impact may occur for example the brick, tile and clay industry.
Recommendations for best welding results
- To get a good result the welding areas should be properly cleaned of rust, grease, soil and similar pollutions.
- Preheat the area to be overlaid to 250°C . 350°C.
- Best results are given by welding at low amperage, not more than 2 layers.
- Gradual cooling is advised.
