Duroxite® 100 Pipe is a high-performance, abrasion-resistant hardfacing pipe designed for use in demanding environments. It features a chromium-rich overlay that enhances its wear resistance, making it ideal for various industries. This hardfacing pipe is engineered for superior wear resistance in the harshest conditions. Duroxite® 100 Pipe comes with options for double or multiple overlay passes. It can be hardfaced on Schedule 40 and Schedule 80 steel pipes, as well as tubing. The overlay pipe can be customized into various shapes, including square-to-round transitions, elbows, T or Y fittings or long sweeps.
Key Benefits
- Consistent wear resistance from the surface to 75% of the overlay.
- Optimal carbide composition for a balanced combination of wear resistance and uniform bonding.

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 Pipe consists of a high percentage of extremely hard primary M7C3 chromium-rich carbides, typically with a hardness of 1700 HK*, evenly distributed within a ductile eutectic austenite matrix. The volume fraction of primary carbides ranges from 30 to 50%, ensuring an optimal balance of wear resistance and uniform bonding.
*) HK is the Knoop microhardness used primarily for very brittle materials.
Fabrication and Other Recommendations
Welding, cutting, forming and machining
Workshop recommendations are available in the Duroxite® overlay brochure, or you can reach out to your technical support representative for further details.
Safety precautions
Welding or cutting Duroxite® products generates gases and harmful fumes that are chemically complex and challenging to categorize. The primary toxic element in these fumes is hexavalent chromium. It is recommended to use proper exhaust ventilation systems, fume-extraction torches, and appropriate protective clothing and respiratory protection for operators.
