chromium carbide overlay wear plate

Production Process
Welding process is the use of the most advanced open arc welding welding process, the various effects of this process on the performance of a very small base , and wear to maximize play. Composite wear plate is ordinary steel (Q235 (A3) or heat-resistant steel (15CrMo, 12Cr! MoV , etc. ) , stainless steel plate formed on the entire volume fraction of more than 50% Cr7C3 carbide -based wear layer , which with high wear resistance , impact resistance, deformable and welding performance, like steel , like direct texturing , cutting and drilling and other processing sectors , processed into mining engineering components to meet the wear and put into use . wear-resistant material with many compared wear-resistant composite plate has its irreplaceable notable features.

We are specialized in researching, developing and producing wear resistant products with many years experience in this field. We have more than 180 employees, with an annual output of 90,000 square meters of wear plates and 9,000 tons of welding consumables.

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(%):25-40. 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.

As you can check on the picture, the carbide (Cr7C3) volume fraction on the microstructure is above 50%.

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.

Using our wear resistant plate as raw material, WODON wear parts are nice looking and with excellent wear resistant strength. Quality of WODON wear parts is one of the best among peers. We produce wear parts like Vertical Mill, Roller Press, Wear Resistant Table Liner, Cement Grinder, Mill Grinder, etc. Our wear parts are available to be cut and profiled by Laser Cutting, Plasma and High Pressure Water Abrasive Cutting according to customer's requirements.

Since 2004, Wodon has more than 200 employees.

Wodon product: flux cored welding wires, chromium carbide overlay steel plates, wear resistant partss, wear pipes, wear fittings.
