XR-Group - Resistant Bimetal Overlay Plate
Bimetal welding wear-resistant alloy steel plate,also named wear resistant bimetal overlay plate. the base is made of ordinary Q235B steel plate, and the wear-resistant layer is composed of advanced alloy welding jointly developed by our company and scientific research institutions.
- Wear resistant bimetal overlay plate is a spray welding technology, which can produce composite materials with high wear resistance and corrosion resistance
- The high-hardness wear-resistant layer has good wear resistance, and is widely used because of its moderate carbon content, comprehensive performance, good strength and weldability.
- This plate can be easily shaped to fit the curve and contour. Welding studs or countersunk screws can be installed for easy board replacement.
- Chromium carbide enables the Wear Resistant Bimetal Overlay Plate to be supported under extreme wear and strong impact, including truck deck lining, hopper, and closed place
- The substrate is not fixed, the board can be selected according to customer needs. Different thicknesses are allowed according to your requirements.

Other Feature and Property
Chemical composition: wear resistant bimetal overlay plate are manufactured by welding one or multiple abrasion resistant layers on a medium or low carbon steel base plate. The overlay alloy has a high amount of chromium carbide hard particles.Microstructure: The carbide (Cr7C3) volum fraction on the microstructure is above 50%.Rockwell Hardness: Chromium carbide hard particles are distributed evenly throughout the layer, creating a strong microstructure, The hardness is between HRC58-65 and depend on the overlay’s thickness.Wear resistance: Our test shows that the wear resistance of wear resistant bimetal overlay plate is 20 times higher than low carbon steel and 8 times than heat treated steel.Flatness tolerance: Flatness tolerance is ±3mm/m.Thickness tolerance: Uniform overlay thickness, with tolerance within 0-0.5mm.
