5. Detail:
The overlay alloy has a high amount of chromium carbide hard particles. These particles are distributed evenly throughout the layer, creating a strong microstructure. The hardness is HRC 55~65 and depends on the overlay's thickness.
The main ingredients of Wodon plate are C(%): 3.0~5.0 and Cr(%): 25~40. This chemical proportion results in a large amount of chrome carbide hard particles. The micro-hardness (up to HV1800) of these particles throughout the layer will guarantee a super wear-resistant surface.

Wodon wear plates are used to make many complex wear parts to be positioned in high wear places. We have several equipments to transform our plates: 7 CNC automatic plasma cutting machine, 7 multi functional bending machines and pressing machines, with high processing capacity operated by engineers and technical experts. We can provide wear plate cutting, bending, punching and welding according to customer's drawings
In the picture there are many cracks, please don't worry. The wear resistant steel plate is not broken and the cracks are good to release the thermal stress. Wodon wear plate is composed of many welding beads and the overlay contains a series of evenly spaced hairlike cracks (The cracks are distributed throughout the overlay thickness, but end up on the base plate's surface). These transversely distributed cracks relief the structure's tension improving wear resistant steel plate's performance like mechanical properties and the overlay don't fall off the base metal.
Wodon hardface wear plate is composed of many welding beads and the wear resistant overlay contains a series of evenly spaced herringbone cracks.These transversely distributed cracks relief the structure's tension improving wear plate's performance. The Cracks are distributed throughout the overlay thickness, but end up on the base plate's surface.Those Cracks don't have any effect to the machining properties and no fall off the wear resistant overlay.
The wear resistant overlay and base plate are metallurgical bonding. The overlay will penetrate into base plate about 0.8~1.8 mm by welding heat. In our tests are the bonding strength reaching up to 350 MPa.
