Duroxite® overlay products are designed for your most extreme wear situations targeting abrasion, impact, heat, metal-to-metal and erosion wear.
Duroxite® overlay products are designed for your most extreme wear situations targeting abrasion, impact, heat, metal-to-metal and erosion wear. Overlay is manufactured by depositing layers of materials on backing materials using arc welding processes. The deposited materials usually provide different properties from backing materials, such as wear resistance, impact resistance, or metal-to-metal wear properties. The performance of Duroxite® saves money and improves productivity in a wide range of applications thanks to higher output and less maintenance.
Duroxite® overlay plates and pipes are delivered with an overlay thickness guaranteed within ±10%. This is consistent throughout the material and between individual plates and pipes. The wear properties of Duroxite® are also guaranteed throughout the overlay down to 75% of the overlay thickness. The remaining 25% of overlay is the transition layer necessary to maintain fusion line bonding to the base material.
Duroxite® is particularly well suited to face sliding wear from exceptionally hard particles. Duroxite® is delivered as plate and wire, ready for installation on your equipment or further application in your workshop. Depending on application, a wide range of products with different properties – hardness, impact resistance as well as heat resistance — is available.

Duroxite® overlay is designed by SSAB’s experts in wear technology and produced by the leading company in welding consumables as well as equipment. Both companies worked out the best possible hard-facing process and chromium carbide welding consumables in order to achieve the best possible properties. This cooperation brought our customers incredible products which provide longer service time than other CCO plates available on the market. Duroxite®’s overlay is measured from top surface to initial base surface, which gives real overlay thickness. This means you get what you are paying for: optimum weld overlay carbide concentration and consistently good abrasion resistance from the top surface through 75% depth of overlay.
Duroxite® is designed to be hard, without giving you a hard time in the workshop. Even the most worn-out equipment can be rebuilt and repaired to perform as new. With our broad product offering, including Hardox® wear plate and Duroxite®, and top-of-the-line processing equipment, you are able to restore products of practically any condition, size and design.
No special equipment is needed to install Duroxite® products. Welding and bolting are the common methods for installing Duroxite® overlay plate or wear parts onto your equipment. When joining base metal use 480 MPa or 560 MPa consumables. Any surface exposed to severe wear should be protected with hard-surfacing consumables. Cap welding a Duroxite® product with Duroxite® Wire ensures the weld will have the same wear resistance, resulting in a consistent service life for the entire overlay product.
When welding or cutting Duroxite® products, smoke is produced containing harmful fumes and gases that are chemically highly complex and difficult to easily classify. The major toxic component in the fumes and gases produced in the process 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.
