Product Description
HARDFACE NICARB-W
CLASSIFICATION
EN 14700 T Ni20
DESCRIPTION Flux cored hardfacing wire containing 50 to 60% tungsten carbides (according to wire diameter)
- Ni-Cr-B-Si matrix
- Optimised combination of toughness and wear resistance due to the heterogeneous weld metal composed of tungsten carbides distributed in a hard and very tough matrix
- Excellent wetting characteristics
APPLICATIONS
Applications requiring extreme abrasion resistance combined with corrosion resistance.
Examples
Brick and clay mill augers, earthmoving equipment (such as plows), rubber mixers and generally all parts undergoing severe abrasion in the mining, steelmaking and public works.
TYPICAL ALL-WELD METAL MECHANICAL PROPERTIES
Hardness: Tungsten carbide: 2360 HV
Ni-Cr-B-Si matrix: 500 – 600 HV
CONDITIONS OF USE
Current type Protection
- DC (+) Shielding gas type M21 (Ar + 5-25%CO2)
- Self shielded
- Select high strength base materials
- Surfaces to be welded should be free of rust, scale, oil or any other contamination, work with low heat input to avoid melting or sinking of the tungsten particles
