Chromium Carbide Overlay

WD-G900 Heat Resistant CCO Wear Plates

WD-G900 Heat Resistant Chromium Carbide Overlay Wear Plates

The heat resistance of WD-G900 comes from its optimized alloy system and controlled addition of Mo and Nb. These elements improve carbide stability at elevated temperatures and help maintain the integrity of the overlay structure under continuous thermal stress. As a result, the material is better able to resist thermal fatigue and retain its functional wear surface at temperatures up to 850°C.

To meet different operating conditions, the alloy composition—particularly Mo and Nb content—can be adjusted according to customer requirements. This allows the wear performance and thermal resistance to be balanced based on specific working temperatures, wear intensity, and equipment conditions.

Surface Hardness
58 – 65 HRC

Temperature Resistance
Up to 850°C

Available Services

  • Cutting

    Wear plates are processed into required geometries using both laser and plasma cutting technologies. Laser cutting is mainly applied where higher precision and tighter tolerances are needed, especially for customized or non-standard wear parts.

  • Forming

    Forming operations are used to reshape flat plates into curved or profiled components. This allows the material to match equipment structures such as curved liners, conical sections, and cylindrical parts.

  • Hole Processing

    • Screen holes: Used for material separation and particle-size control.

    • Through holes: Includes plug-weld holes, shaft-passing holes, and other installation hole types.

    • Countersinking: Supports manual shim countersinking, rotary-cut countersinking, and precision machined countersinking.

  • Stud Welding

    Stud welding, whether manual or automatic, is used to provide firm fastening points for wear liners, supporting accurate positioning and stable installation.

  • Welding

    Provides welding, assembly, and structural fabrication of processed wear plates, producing complete wear-resistant components according to customer drawings.

Typical Applications

• Chute Liners
• Curved Coal Drop Pipes
• Hoppers
• Screen Plates
• Slag Discharge Troughs
• Distributors
• Bins/Silos
