Duroxite® 101

Duroxite® 101 is manufactured by depositing a chromium-rich carbide overlay on Hardox® 450 backing plate. The hardfacing overlay is suitable for severe abrasive wear and impact applications.

With its optimum carbide concentration, consistently good wear resistance from top surface through 75% depth of overlay, and Hardox® backing plate, Duroxite® 101 provides a better combination of wear and impact resistance compared to the traditional mild steel backing overlay plate.

Key Benefits

  • Designed to better withstand plastic deformation due to its high yield strength flexing back after impact
  • Stronger support due to high hardness of Hardox® and better bonding between overlay and base steel
  • When overlay wears off Hardox® 450 backing plate will wear at a lower rate than mild steel providing a greater safety margin
  • Better performance for impact situations than Duroxite® 100 at elevated temperatures up to 350° C (660° F), but impact resistance is best at room temperature

Typical Applications

Duroxite® 101 is widely used in the mining, cement and power generation industries. Some specific applications include:

  • Mining: Loader bucket liners, bucket lip and side shrouds, jaw shrouds
  • Cement: Heel pads and dewatering conveyors
  • Power: Coal discharger chutes
