Type
Nickel based flux cored wire for hardfacing containing a high amount of tungsten carbides.
classification

DIN
8555: MF 21-GF-55-CGTZ
Applications
This Ni-based alloy provides an excellent corrosion resistance combined with extreme abrasion resistance. OA WC2 (Ni) can be applied on all sorts of steels except on cast iron or Mn-steel. This alloy is the most wear resistant type in most hardfacing applications. In case of very fine dust abrasion It might happen that the matrix will be washed out and looses the imbedded Tungsten carbides, in this case another hardfacing product should be considdered.

Propriétés

2400 HV nickel based corrosion resistant hardfacing alloy containing 60% tunsten carbides. OA WC2 (Ni)  has excellent flow and wetting characteristics. Multi-layer deposits are possible and worn parts can be rebuild without removing the old material. Crushed cast carbide will guaranty a long life for several wear applications. Best to be used with shielding gas M13 (Argon with 1% Oxygen) approx. 15 litres per minute.
