Duroxite® 100 Plate
Duroxite® 100 Duroxite 100 Overlay Plate Duroxite 100 Wear Plate Duroxite 100 Hardfacing Plate Duroxite 100 Overlay Plate Duroxite 100 Abrasion Resistant Plate Duroxite 100 Chromium Carbide Overlay
Duroxite® 100 is a high-performance wear-resistant overlay plate designed to provide superior protection against wear, abrasion, and impact in harsh environments. This hard facing plate is designed to withstand severe abrasive wear and moderate to low impact conditions. The multi-layer overlay plate maintains its full wear resistance up to 350 ºC (660 ºF) and typically achieves a surface hardness of 55 HRC even at elevated temperatures of up to 540 ºC (1000 ºF). Duroxite® 100 is offered in both single-layer and multi-layer options, with overlay plate thicknesses of up to 20 mm (3/4”).
Key Benefits
- Consistent wear resistance from the surface to 75% of the overlay plate.
- Optimal carbide composition for a strong balance of wear resistance and uniform bonding.
- Enhanced formability due to the staggered cracking pattern on the overlay plate surface.
Typical Applications
Duroxite® 100 is commonly used across industries such as mining, power generation, cement, dredging, steel production, waste management, glass manufacturing, and pulp and paper. Some specific applications include:
| Industry | Applications |
| Mining | Chutes, hoppers, truck bed liners, dozer blades, shovel buckets, dragline buckets, and excavators. |
| Cement | Separator guide vanes, discharge cones for clinker storage bins, chutes for conveying sintering ore, outlet ducts for clinker grinding mills, and receiving hoppers. |
| Dredging | Dredging pipes and pumps, suction pipelines, pump discharges. |
| Steel | Fan blade/housings, coke vibrating screen plates. |
| Power | Coal handling chutes, coal feeder liners, crusher screen plates, classifier cones, journal liners, silo bunkers. |

1) Surface hardness is measured on machined flat surface just below overlay surface.
2) ASTM G65 – Procedure A weight loss, is a standard test measuring sliding abrasion resistance using a dry sand/rubber wheel apparatus. ASTM G65-Procedure A is the most severe test method.
3) ASTM G65 – Procedure A weight loss, wear test is conducted at 75% depth of the overlay materials to ensure consistently good wear resistance from the top surface through to the depth of 75% of the overlay.
Microstructure
The microstructure of Duroxite® 100 consists mainly of hard primary M7C3 chromium-rich carbides, which have a typical hardness of 1700 HK*), evenly distributed within a ductile eutectic austenite matrix. The volume fraction of primary carbides ranges from 30% to 50%, ensuring a balanced combination of wear resistance and uniform bonding.
*)HK is the Knoop microhardness used primarily for very brittle materials.
Tolerances
Thickness
The thickness tolerances for both overall and overlay plates are guaranteed to be within ±10% of the specified thickness.
Flatness
The plate flatness tolerance is guaranteed to be within ±3 mm (±1/8”) over a 1.5 m (5’) plate length for plates with dimensions up to 1.5 m (5’) x 3.0 m (10’). For plates larger than 1.5 m (5’) in width and 3.0 m (10’) in length, the following flatness guarantees apply.

Fabrication and Other Recommendations
Welding, cutting, forming and machining
For recommendations, please refer to the Duroxite® Product brochure or contact your local technical support representative.
Always observe the necessary health and safety precautions when bending, welding, cutting, grinding, or performing any other work on the product.
Safety precautions
Welding or cutting Duroxite® products generates gases and harmful fumes that are chemically complex and challenging to categorize. The primary toxic substance in these fumes is hexavalent chromium. It is recommended to use proper exhaust ventilation systems, fume-extraction torches, and appropriate protective clothing, along with respiratory protection for operators.
