Heavy-Duty Grab Bucket Liners for Port Handling: Enduring Massive Ore Loading Stress

high hardness wear plate

We use our own developed CNC automatic welding machine with multi welding guns to weld our own hardface wear plate. These can overcome the problems like: low productivity, poor flatness and overlay falling off etc. This is a high automation level machine, each welding gun can operate independently and restart exactly from the point it had stopped, simplifying the operation process. The Surface welding plates manufactured by this equipment have many advantages like flat surface, micro and irregular cracks, and uniform hardness being very well accepted by our customers, which like the above picture showing. The following picture shows CNC automatic machine with multi welding guns.

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 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.
