Wodon wear and impact resistant chromium carbide overlay (CCO) plate
Our company R&D producted bimetallic wear plate have four different types.
1. generally wear plate with Open arc welding: base plate + chromium carbide abrasion resistant welding layer with good abrasion resistance, Hardness HRC 55-63 (HV 600-780) and chemical compostion C: 2.5-5.0% Cr: 20-30 %
2. super wear plate with Submerged arc welding: base plate + high chromium carbide abrasion resistant welding layer with super good abrasion resistance, Hardness HRC 58-65 (HV 600-780) and chemical compostion C: 3.0-5.5 % Cr: 25-40 %
3. wear plate with Impact resistance: base plate + chromium matrix with other metallelementes resistant welding layer with good impact resistance and super good abrasion resistance
4. wear plate with Heat resistance: base plate + chromium matrix with other metallelementes resistant welding layer with good heat resistance (up to 900 °C) and super good abrasion resistance

What is Wodon wear plate?
Wodon wear resistant steel plates 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. These particles are distributed evenly throughout the layer, creating a strong microstructure. The hardness is HRC 58~65 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 Cr7C3 chrome carbide hard particles. The micro-hardness (up to HV1800) of these particles thoughout the layer will guarantee a super wear resistant surface.
The overlay and base plate are metallurgical bonding. The overlay will penetrate into base plate about 0.8~1.8 mm, reaching up to 350 Mpa in our tests.

Wodon wear plates are used to make many complex wear parts to be positioned in high wear places. We have several equipment to transform our plates: six of CNC automatic plasma cutting machine, 4 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. The above picture shows the welding fusion line of Open arc welding (the up one) and Submerged arc welding (the down one).
