DURAPLATE D31
Oscillated-Bead Hardfacing Steels
Duraplate® D31 is a chromium carbide hardfaced overlay plate designed to withstand severe abrasion while remaining easy to integrate on your equipment.
Its hard overlay deposited on a mild steel backing provides an excellent balance between durability, ease of fabrication, and cost.
Suitable for chutes, hoppers, linings or feeders, the D31 delivers effective protection in demanding environments while ensuring good weldability.
Technical & General Information
Hardness:
Thicknesses & Formats :
Base thickness + overlay thickness (mm)
5+3 / 6+4 / 8+5 / 12+8
2900×1800
Mechanical Properties :
The overlay itself has no intrinsic mechanical properties; the backing steel it is welded to provides suitable characteristics (S235, S355, HLE, …)
Yield Strength RP 0.2: 355 MPa
Tensile Strength RM: 510 MPa
Elongation A%: 22
Typical values for S355 steel
Fabrication :
Duraplate’s exceptional quality allows cold forming according to specifications depending on the combination of overlay and backing thickness.
Sheets heated above 1200°C can be hot-formed without altering properties.
Weldability :
All standard welding procedures apply to Duraplate.
The overlay can be repaired or supplemented with DURCOR electrodes or wires of the same composition as the filler metals.
Main applications of Duraplate D31
- Vibrating feeders
- Skips
- Chutes
- Hoppers
- Loader bucket
- Bull blade
- Dumper bottom
- Scalpers
- Rails and sliding shoes

Why choose Duraplate D31 ?
Duraplate® D31 provides effective protection against abrasion thanks to its chromium carbide overlay, making it a robust solution for highly stressed areas.
Its mild steel backing allows for easy fabrication, whether cutting, forming, or welding, without special integration constraints.
It also helps extend maintenance intervals due to a service life significantly longer than conventional steels.
Finally, it is a cost-effective and balanced solution, ideal for equipment exposed to severe wear without the expense of a premium straight-bead overlay plate.
