Product Specification

• Excellent resistance to mineral wear and thermal degradation
• High-temperature hardness retention (only ~10% loss at 650 °C)
• Suitable for non-corrosive, low-impact environments
• Recommended with buffering layer on sensitive or pre-hardened surfaces

• High Carbon and Chromium
• Boron for carbide formation
• Hypereutectic carbides in a hard matrix
• Ledeburitic structure with thermal wear stability

• For optimum results, perform welding in two layers.
• The resulting weld deposits cannot be heat treated, machined, or forged.
• When overlaying previously hard-faced surfaces, use a buffer layer of Cordiff 200K or Cordiff 250K before applying the final layer.

• Iron ores
• Coal chutes
• Coke oven screens
• Pulverizer hammers
