Duroxite® 500 is a premium wear-resistant overlay plate designed to deliver superior protection against extreme wear and impact in demanding industrial environments. Engineered for outstanding performance in abrasion-resistant plate applications, it delivers an exceptional combination of sliding wear resistance and high impact durability in both dry and wet (slurry) conditions. Capable of withstanding temperatures up to 1100 °F (600 °C), Duroxite® 500 is available in both single and double-layer configurations to suit demanding environments.
Duroxite® 500 is developed with a specialized overlay plate that integrates ultra-fine chromium-niobium-rich borocarbides, achieving a refined grain size down to 500 nm. These advanced borocarbides, which are 200 times finer than the primary carbides found in traditional chromium carbide plates like Duroxite® 100, are fully bonded within a ductile matrix. This structure eliminates premature pull-out delamination, crack nucleation, and bridging, ensuring an extended service life in extreme wear conditions. The result is a superior hardfacing plate that surpasses conventional solutions in both impact and wear resistance.
Key Benefits
- Specially designed for applications requiring high impact-resistant plates and superior abrasion resistance.
- Contains an ultra-fine borocarbide phase, significantly improving performance over traditional chromium carbide plates.
- Offers consistent abrasion-resistant plate properties from the surface down to 75% of the overlay thickness.
- Provides six times the impact resistance compared to Duroxite® 100, as demonstrated in laboratory testing.
- Maintains uniform hardness between 67-70 HRC for single and multiple-layer clad plates, retaining approximately 60 HRC even after exposure to elevated temperatures up to 1100°F (600°C).

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
Duroxite® 500’s structural wear plate technology is built around an ultra-fine borocarbide matrix, featuring a 60-70% borocarbide volume fraction. Scanning Electron Microscopy (SEM) and Energy Dispersive Spectrometry (EDS) confirm that these refined borocarbides are niobium-rich and chromium-rich, offering superior hardness and wear resistance. This innovative metallurgy makes it a leading toughened steel plate for impact and abrasion-intensive environments.
Tolerances
Thickness
Overall and dual-metal wear plate thickness tolerances are guaranteed within ±10% of specified dimensions.
Flatness
Plates maintain precise flatness within industry standards over a 1.5 m (5′) length for dimensions up to 1.5 m x 3.0 m (5′ x 10′).

Fabrication and Other Recommendations
Welding, cutting, forming and machining
For detailed recommendations, refer to the Duroxite® Product Brochure or contact your local technical support representative for further assistance.
Safety precautions
Welding or cutting Duroxite® products generates gases and hazardous fumes that are chemically complex and challenging to classify. The primary toxic substance in these fumes is hexavalent chromium. To ensure safety, operators should use appropriate exhaust ventilation systems, fume-extraction torches and wear suitable protective clothing and respiratory equipment.
