Carbo Durit E – 4 mm

  • Standards DIN 8555 E21-GF-UM-60-GP
  • DIN EN 14700 E Fe20
  • Welding positions PA, PB
  • Flux-cored wire equivalent CARBO F- Durit Fe


  • CARBO DURIT E is a steel tube filled with fused tungsten carbides.
  • It is a dip-coated electrode suitable form Manual Arc [MMA] welding on AC as well as on DC.
  • The weld metal consists in a tungsten-steel-matrix with embedded tungsten carbides.
  • The extraordinary hardness of the fused tungsten carbides (WSC) of approx. 2300 HV imply the high build-up wear resistance.
  • The carbon content of the base metal should not exceed 0,45 % in order to avoid lack of fusion. However, the base material should have enough strength to avoid the penetration of the build-up in the base material.

Typical applications

  • Hardfacing of tools and machine parts in the mining,
  • Road construction, well digging, civil engineering,
  • Deep drilling technology, where strongest abrasion by minerals may occur.


  • To get the best results the welding areas should be properly cleaned of rust, grease, soil and similar pollutions.
  • Preheating to 350-500°C is recommended.
  • The lowest possible welding current should be used to avoid the melting of the carbide particles.
  • The selection of the grain size and the rod diameter depend on the application and the size of the tool to be hard faced.
  • Lower particle sizes are recommended when the wear from abrasion is dominant, bigger sizes for tool cutting faces for superior cutting results.
