Overlay plates for various wear applications
Duroxite® overlay plate products are used as liner plates and wear parts in a variety of primarily sliding wear applications. The plates are available in different versions, with mild steel or Hardox® wear plate as base plate for additional strength.
Matching Duroxite® plates to your application
Duroxite® overlay plates are classified so that the hardfacing material matches the type of application and wear environment.
SSAB Tech Support is happy to answer any questions you may have on the selection of Duroxite® wear plates.
Overlay plates for sliding wear
In this category you’ll find Duroxite® 100 and Duroxite® 101 overlay plates where chromium carbides make up the hardfacing layer. Highly suitable for many sliding wear applications with low to moderate impact and temperatures up to 350 °C. Duroxite® 101 has a Hardox® base metal for additional strength against plastic deformation.
Overlay plates for severe sliding wear
Duroxite® 200 and Duroxite® 201 overlay plates are designed for more severe abrasive conditions with low to moderate impact. Duroxite® 200 and Duroxite® 201 have a hardfacing layer consisting of extremely hard complex carbides. They can provide a service life several times longer than that of chromium carbide overlays. They can also take higher temperatures, up to around 600 °C. Duroxite® 201 has a Hardox® base metal for additional strength against plastic deformation.
Overlay plates for extreme sliding wear
Duroxite® 300 overlay plate has a hardfacing layer of ultra-fine complex borocarbides making the plate extremely resistant against the hardest abrasive and quartz-rich materials. It provides an even longer service life than that of complex carbides. It is well suited for wet and dry applications that are particularly difficult to maintain, and uptime is critical to the operation. Duroxite® 300 can take moderate impact and temperatures up to 600 °C.
Overlay plates for sliding wear and high impact
Duroxite® 500 overlay plate can withstand both sliding wear and high impact from rocks thanks to its specially formulated hardfacing layer of ultra-fine complex borocarbides. The complex borocarbides prevent spalling and cracking when exposed to high impact. Duroxite® 500 can work in temperatures up to 600 ˚C.

Duroxite® with a harder baseplate
Duroxite® 101 and Duroxite® 201 overlay plates have Hardox® 450 as baseplate. This gives a higher performing plate compared to using a mild steel baseplate in a case where the abrasive material reaches down to the baseplate. The strength and toughness of a harder baseplate also makes the overlay plate stronger and more resistant to deformation.
