Bi-Metal Shields : DURCAST
DURCAST achieves the impossible: making highly wear-resistant white cast iron easily weldable.
DURCAST: Weldable White Cast Iron
Very high wear resistance
DURCAST® Block : The Perfect Union of Steel and Cast Iron for Ultimate Wear Resistance
As part of the range of high-performance materials carefully selected by PRODUR, the DURCAST® wear block is composed of chrome-molybdenum cast iron blocks metallurgically bonded to a weldable S235 steel base.
White cast irons, renowned for their hardness and exceptional wear resistance, often pose challenges for welding and fastening techniques due to their brittleness. On the other hand, S235 steel is a relatively easy-to-work material but offers limited anti-wear performance.
By cleverly combining these two materials, the DURCAST block is achieved. This hybrid material leverages the positive properties of each component, providing an optimal solution for demanding applications.
| BASE S235 | WHITE CAST IRON BLOCK |
|---|---|
| High ease of welding Machinability Easy formability Ability to withstand shocks (shock-absorbing function) |
Very high wear resistance Perfect behavior under severe abrasion conditions Resistance to corrosive environments due to chrome content Specific shapes obtained through molding |

Fields of application
DURCAST® is particularly designed for treating areas with severe and limited wear, areas with severe abrasion under heavy stress, or impact zones.
Crusher side liners,
Bucket cheeks,
Bucket bottoms,
Trencher,
Stone boxes,
This list is not exhaustive; feel free to consult with us to determine if DURCAST® is the suitable solution for your specific needs.
Fixing method for the DURCAST® wear block
He peripheral welds of the wear block must be protected:
Either by positioning the elements to prevent the movement of abrasive materials on the weld (staggered mounting) Or by using DURCOR tubular electrodes for final protective pass Or by combining both techniques.
