Key Performance Advantages

? Enhanced Abrasion Resistance: Optimized M7C3 carbide formulation outperforms traditional chromium carbide deposits in severe wear environments
? Self-Shielded Convenience: Eliminates costly shielding gas, ideal for field repairs and remote job sites
? High Hardness: 60-62 HRC hardness ensures exceptional durability against earth, sand, and abrasive materials
? Versatile Application: Suitable for both moderate impact and extreme abrasion conditions

Industrial Applications

Perfect for hardfacing components including: Gyratory crusher cones/mantles, slurry pipes, dredge pump bodies, extruder screws, mining equipment, blast furnace bells, sugar mill crusher hammers, coal pulverizer rolls, and shredder components.

Quality Certifications

Meets international standards: AS/NZS 2576-2005 2560-B7, DIN 8555 G 1-300-P, and EN 14700 TFe8.

Differentiation

Unlike conventional hardfacing wires, HC-O combines high chromium carbide content with a martensitic matrix, delivering superior wear resistance while maintaining operational convenience through self-shielded technology. Limited to 2 layers, it balances hardness with practical application flexibility.

FAQ

Q: Is preheating required?
A: Consult welding procedure specifications for base material compatibility.
Q: Can this wire be used on cast iron?
A: Recommended for carbon steel and low-alloy steel substrates.
Q: What causes post-weld relief checking?
A: Normal stress relief phenomenon in high-hardness deposits, controlled by limiting layers to 2.
