DURAPLATE D45T
Straight-Bead Hardfacing Steels
Duraplate® D45T is a straight-bead hardfaced overlay plate specifically designed to withstand the most severe wear conditions, including high temperatures up to 700°C.
Its complex carbide overlay — chromium, niobium, molybdenum, tungsten, and vanadium — provides exceptional protection against abrasion and thermal stresses.
Deposited on a mild steel backing, this plate combines wear performance, forming flexibility, and ease of integration: cutting, rolling, and welding remain simple and reliable despite the very high hardness of the overlay.
The longitudinal fusion of the beads ensures a flat, uniform, and durable surface without compromising long-term performance.
Technical & General Information
Hardness :
62-64 HRC
Thicknesses & Formats :
*Base thickness + overlay thickness (mm)
5+3 / 6+4 / 8+5 / 10+9
2900 × 1900
Mechanical Properties :
The overlay 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 D45T
- Components exposed to severe wear and high temperatures
- Steel industry
- Cement plants
- Recycling
- Power plants
- Asphalt plants

Why choose Duraplate D45T ?
Duraplate® D45T is the ideal solution for areas exposed to extreme abrasion combined with high temperatures.
Thanks to its complex carbide overlay, it maintains hardness and metallurgical stability up to 600°C, whereas a conventional plate would rapidly lose performance.
Its low dilution and homogeneous structure, achieved through the straight-bead process, provide superior resistance to fatigue, forming, and mechanical stresses.
Easy to cut, roll, or weld, D45T delivers long-lasting protection for critical equipment in cement plants, steel mills, power plants, or recycling facilities, while minimizing maintenance and unplanned downtime.
It provides a high-performance, durable, and reliable solution for industrial environments where temperature and abrasion are key factors.
