Hardface NiCarb-W x 2.0mm

Description

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
