Loader Bucket Edge Wear Plate: Ultimate Protection for Intensive Loading Tasks

Chromium Carbide Overlay Wear Plate for Heavy-Duty Equipment

• Chromium carbide composite cladding fusion bonded to a mild steel backing material.

• The deposit has been realized by means of oscillated welding and a wear resistant coating applied by submerged arc welding.

• Fine cracks perpendicular to the welding bead is normal due to natural stress relieving in a very hard matrix.

• Very high volume of chromium carbides evenly distributed throughout the uniform thickness of the deposit.

• Plate hardness ranges from HRC58-65.

• Suitable for applications involving high abrasion and low to medium impact.

• AS2576-2355/2576-2455

Supported by patent technique, Wodon high chromium carbide overlay wear plates are manufactured under tightly controlled parameters within a quality management system. Various thickness is available.

Why our wear plate has such good wear resistance?

1. The overlay chemical composition is the key

The main ingredients of Wodon plates are C(%) :3.0-5.0 and Cr(%):25-45. This chemical proportion results in a large amount of Cr7C3 chrome carbide hard
particles. The micro-hardness (up to HV1800) of these particles throughout the layer will guarantee a super wear resistant surface.

Performance test:

Test equipment: Quartz sand rubber wheel abrasion test machine.

Conditions: Choosing same dimension specimens for different materials and wear plate producers, and put them under the same wearing working conditions
in our testing equipment.

          45 minutes for each specimen.

Results: The test results show that the life span of Wodon wear plate is 2.5 times higher than domestic wear plates and 1.5 times than imported ones.

2. Chromium carbide microstructure

The wear resistance of wear plate depends mostly on the hardness, shape, size, amount and distribution of the chromium carbide hard particles.

3. Bonding strength between the overlay and base plate.

The overlay and base plate are very well bonding. The overlay will penetrate into base plate about 0.8mm-1.8mm, reaching up to 350Mpa in our tests.

Wear Part Production

Cutting

Overlay can be cut with plasma, laser, and water jet.

Machining

The overlay surface is not machinable. However, Wodon can provide Overlay with countersink holes and tapped holes.

Forming

Overlay can be cold formed or rolled. 

Welding

Overlay can be welded on the mild steel base plate surface.

Our production capacity of wear parts is 7,000 tons per year.
