Laminated Wear Plates – It is a combination of high chromium white iron metallurgically bonded to a mild steel backing plate.
Hardness: 700BHN (HRC62-66)
Thickness: 12mm to 70mm
Large sizes available(600mmX900mm)
Rock Box Edges
Material: Chrome white iron wear casting vacuum brazed onto mild steel base.
The smallest thickness for wear material we can make is 6mm.
1. Hardness: 63HRC/700BHN. The usage life is at least 2 times higher compared with overlay/hardfacing wear plates, at least 7 times longer than A.R type steels 360/400BHN. The thicker ones such as 20mm above wear, the usage life is much more longer. The wear resistance performance is the same from wear surface to the welding face.
2. Wear surface is very smooth and flat, media is not easy to stick on.
3. It can make with different shapes and sizes.
4. Better cost-efficient. Unit price is about USD5.5—USD7.5 per kilogram.
Weakness: for big sheet size, wear casting could be joint ones, not a whole sheet. For example, wear plate 1443x349x25/6mm(25mm wear, 6mm base), the wear material will be jointed with 4pcs, and mild steel base will be joint with 2pcs, joint gap is below 2mm
Suitable for use in chutes, hoppers, bins, liners, impact walls, rock boxes and a variety of other applications.
Very easy to use, no pre or post heating when welding. overlay wear plates
