Applications
Designed for heavy-duty industrial wear protection: Gyratory crusher cones/mantles, slurry pipes, dredge pump bodies, mining equipment, extruder screws, coal pulverizer rolls, and sugar mill hammers. Perfect for earthmoving, mining, and aggregate processing machinery.
Performance Advantages
- Superior abrasion resistance vs. standard chromium carbide wires
- Self-shielded design for outdoor/remote applications
- 60-62 HRC hardness for extreme wear environments
- M7C3 carbide structure for extended component lifespan
- Minimal post-weld checking (normal relief cracks)
Quality Assurance
Manufactured with high-grade ferro-alloy additives and complies with international standards (AS/NZS 2576, DIN 8555, EN 14700). Each spool undergoes rigorous quality testing to ensure consistent performance and reliability.
Differentiation
Unlike conventional hardfacing wires, HC-O combines high carbide content with a martensitic matrix, delivering unmatched wear resistance in severe abrasive conditions. Its gasless design eliminates shielding gas costs while maintaining deposition efficiency.
FAQ
Q: Can I use more than 2 layers?
A: Limited to 2 layers for optimal performance; additional layers may reduce impact resistance.
Q: What polarity is required?
A: Torch electrode positive (DCEP) polarity is mandatory.
Q: Is preheating necessary?
A: Recommended for thick sections; consult technical data sheet for specific requirements.
