Description

CARBO DURIT Ni E – 4 mm

  • Standards DIN 8555 G 21-GF-UM-50-CG
  • DIN EN 14700 E Ni20
  • Welding positions PA, PB
  • Flux-cored wire equivalent: CARBO F-DURIT Ni

Characteristics

  • CARBO DURIT Ni E is a tubular rod containing fused tungsten carbides in a nickel base matrix alloy. This alloy is especially designed for manual arc welding.
  • The weld metal is composed of 60 to 65 % fused tungsten carbides which are embedded in a matrix alloy containing 35 to 40 % NiSiB.
  • CARBO DURIT Ni E is “unique” in that it produces a smooth, clean surface.
  • The alloy flows extremely well, due to the low melting point of between 900 and 1000°C.
  • The nickel based matrix alloy provides excellent resistance to acids and other corrosive media.
  • CARBO DURIT Ni A is used for applications which are subject to extremely heavy abrasive wear and corrosive media at the same time.

Typical applications

  • Hardfacing equipment parts made of ferritic and austenitic steels.
  • Mixer blades, milling plates, conveyor worms, stabilizer blades, slurry pump valves
  • Moulding sand preparation plants
  • Corrosion resistant welded coatings on parts which are subject to strong abrasive wear, e.g. in the chemical industry and the food industry.

Recommendations for best welding results

  • Thoroughly clean the welding zone. It should be exempt from grease, scale, corrosion, and similar contamination.
  • Preheat the work piece to 300 – 500° C.
  • During the welding process the local base material temperature has to be increased to 650°C, however, overheating should be avoided.
