Wear Block – White Cast Iron + Weldable Base

Durcast is a wear-resistant block combining very hard martensitic white cast iron with a weldable S235 steel base.

This unique composite combines the extreme resistance of cast iron in the wear zone with the weldability of S235, making it possible to securely fix a material that is normally unweldable.

Durcast is designed for severe and localized wear areas requiring very high mechanical resistance.

Main Applications of Durcast

Durcast is used to reinforce areas exposed to very severe localized abrasion:

Rock boxes, bucket bottoms
Rails, wear pads, crusher side liners
Hammers, cutters
Conveyor belt discharge points
Severe impact zones
Tooth holders, scraper blades

Advantages of Choosing Durcast

Durcast provides the extreme resistance of white cast iron in areas where it would normally be impossible to fix.

Thanks to its weldable S235 base, installation is simple, reliable and secure.
The high-performance metallurgical bond eliminates any risk of separation between the steel and the cast iron, even under very high mechanical stresses.

Durcast therefore represents an ideal solution to extend the service life of critical areas, reduce production downtime and maintain the performance of the most heavily stressed equipment.
