HARDFACE NICARBW
EN 14700 T Ni20
• 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 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
