Duroxite® 101 US

Download data sheet

General Product Description

Duroxite® 101 US 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 Hardox® backing plate, Duroxite® 101 US 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 US at elevated temperatures up to 350° C (660° F), but impact resistance is best at room temperature

Typical Applications

Duroxite® 101 US 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

For more information on applications see the Duroxite® workshop brochure.

Tolerances

Thickness

Overlay thickness tolerance can be guaranteed within ±10% of specified thickness.

Flatness

Flatness is guaranteed over a 5 ft section of the plate. For plate sizes up to 5’ x 10’, the flatness tolerances follow the 5’ x 10’column of the tables. For wider plates (6’ x 10’or 8’ x 10’), the guarantees are as shown in the tables.

Delivery Conditions

Duroxite® 101 US is normally supplied in an as-welded condition, but can also be supplied in a ground condition upon request.

Fabrication and Other Recommendations

Welding, cutting, forming and machining

Recommendations can be found in the Duroxite® workshop brochure, or consult your local technical support representative.

Appropriate health and safety precautions must be taken when bending, welding, cutting, grinding or otherwise working on the product.  

Safety precautions

When welding or cutting Duroxite® products, gases and harmful fumes are produced that are chemically complex and difficult to classify. The major toxic component in the fumes is hexavalent chromium. The proper exhaust ventilation equipment and fume-extraction torches are recommended, as well as suitable protective clothing and respiratory protection for operators.
