Duroxite® overlays for extreme durability
Duroxite® overlay products are designed for your most extreme wear situations with abrasion, impact, heat, metal-to-metal and erosion wear. Duroxite® fights wear for a long time thanks to its unique guaranteed wear properties down to 75% of the overlay thickness.
Wear protection the Duroxite® way
Duroxite® overlay products can add weeks, months, even years of troublefree operations to your most extreme wear situations. The outstanding performance of Duroxite® is the result of hardfacing a metal by welding different types of chromium or complex carbides on top of the base material. By carefully composing the hardfacing material, each Duroxite® product is optimized for different wear situations and abrasive materials.

Choose the right overlay
The ultimate Duroxite® product for your application depends on the material, whether it’s rock, sand, gravel or any other abrasive material striking or sliding along the surface of your wear part. It also depends on the angle and speed of impact as well as the operating temperature.
Find the right overlay product to boost the performance and productivity of your equipment and parts.

Duroxite® overlay products come with guarantees that are unique for the overlay market. When you for example order 6 mm overlay on a 6 mm baseplate, you know that this is what you get within ±10%. This is consistent throughout the plate and from plate to plate.
The wear properties are also guaranteed down to 75% of the hardfacing layer’s thickness as opposed to just the surface of the layer. The remaining 25% is the transition layer necessary to maintain good bonding to the baseplate.
Hardox® as a baseplate
Hardox® wear plate as a baseplate is available in Duroxite® 101 and Duroxite® 201. Using Hardox® wear steel as baseplate makes for an outstanding composite material. Hardox® wear plate has a unique combination of hardness, strength and toughness. The hardness gives a greater wear safety margin compared to using a mild steel baseplate if the hardfacing layer is worn down. The strength and toughness of Hardox® increase the overlay product’s resistance to impact forces.
Duroxite® in fabrication
Duroxite® is designed to be hard without giving you a hard time in the workshop. No special equipment is needed to install Duroxite®. Welding, bolting and stud welding are the common methods for installing Duroxite® wear parts or overlay plate on your equipment. For more information on installation, see Duroxite® brochure.
One of the key benefits of Duroxite® is the excellent formability due to a staggered cracking pattern on the overlay surface. This simplifies bending of the plate and ensures a smooth flow of the processed materials.
Proven performance
Duroxite® is the natural choice for industries such as quarrying, mining, cement, concrete, energy, steel mills, recycling and many other areas where abrasive materials require extremely hard surfaces.
