Wodon chromium carbide wear-resistant parts for steel mill slider

1. Grade: Q235/Q345+Chromium Carbide Overlay

2. Size: customised

3. Standard: Enterprise standard

4. Certification: ISO9001, SGS, BV.

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 prime chromium carbide (Cr7C3) hard particles. The micro-hardness (up to HV1800) of these particles throughout the layer will guarantee a super wear resistant surface.

Wear resistance test:

Test equipment: Quartz sand rubber wheel abrasion test machine.

Conditions: a) choosing same dimension specimens for different materials and wear plate producers

                      b) put them under the same wearing working conditions in our testing equipment.

                      c) 45 minutes for each specimen.

The blow 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 prime chromium 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 0.8 mm~ 1.5 mm, reaching up to 350 Mpa in our tests.

We have our own Quality Inspection Technology Department and the team are made of many experience exports with material science bachelor-degree and the leaders with material science master-degree. In the pictures you can also see our equipment in our laboratory. Our inspection team make regular testing on raw material, production process and our products according our company's strict policy.

In our Laboratory there are many equipments to test our products. Portable Spectrum can test easily the chemical composition of wear plate surface . We also bought a new Spectro MAXx (a desktop spark direct reading spectrometer) to read the chemical composition directly from the powder.

We have a series of metallography experiment instruments, so the metallurgical microstructure can be analysed. The chromium carbide volume fraction on the microstructure is above 50%.

We use Rockwell hardness tester to test small sample from our wear plate. The test result are very accurate. We also have portable ultrasonic hardness and thickness testers to test easily the hardness and thickness of wear parts on the scene.

The desktop Rockwell hardness tester can very accurately measure the hardness of small samples

The portable ultrasonic hardness tester can easily measure the surface hardness of wear parts on the scene.

The portable spectrum can easily test the chemical composition on the scene.

The metallurgical microscope can test the mircostructure and calculate the chromium carbide volume fraction easily and  accurately.

The portable ultrasonic thickness meter can easily test the thickness of wear plate or work work piece.

This model of test machine is not any standard, but it is mainly for contrast reference to test the wear resistance.

Packing Details  : steel pallets or plywood carton and pallets

Jiangsu Wodon Wear Resistant Material Co., Ltd, founded in 2014, is a professional manufacture speacialising in reserching and developing wear resistant materials. Our main products are wear resistant plates, machined parts and flux cored welding wires, which are widely used in coal mining, cement, power plant, steel mills, machinery and other consumable areas. Our wear plates can greatly prolong the maintennace time, thus reducing maintenance cost in practical application.
