Duraplate D31T
Straight-Bead Hardfacing Steels
Duraplate D31T is a straight-bead hardfaced overlay plate with a chromium carbide base, hardness of 60–62 HRC, and hard phases mainly at 1650 HV.
It withstands very severe abrasion up to temperatures of 350°C and moderate impacts.
For high-abrasion applications with strong impact, we recommend our Duraplate D38T overlay plate.

Duraplate D31T: The High-Performance Choice for Straight Beads
The straight-bead deposition, a key feature of Duraplate wear plates, provides:
- A more homogeneous overlay (fine carbides)
- A more consistent overlay thickness
- Finer and better-distributed cracks
- Low dilution into the backing plate
These four factors give Duraplate® straight-bead grades superior wear resistance compared with conventional hardfacing processes.
This straight-bead overlay, applied by Welding Alloys, ensures better control of the dilution zone, reducing weakening of the base plate and minimizing crack risks during forming and fatigue-related impacts over time.
