CCO Plate Technical Details

Chemical Composition: chromium carbide steel plate is a kind of wear-resistant alloy, with a lot of hard particles of chromium carbide deposited on the medium and low carbon base metal.
Standard thickness of chromium carbide plates mainly include: 3+3、4+4、5+5、6+4、6+5、6+6、8+5、8+6、8+8、10+5、10+6、10+7、10+8、10+10、12+5、12+6、12+7、12+8、12+10、12+11、12+12、14+6、14+8、14+10、16+6、16+8、16+10、18+6、18+8、18+10、20+6、20+8、20+10、30+10、40+10
Micro-structure: The volume fraction of Cr7C3 carbide in the metal lo-graphic structure of wear-resistant layer is more than 50% .
Hardness: According to the wear-resistant layer thickness, different usage, wear-resistant alloy surface hardness HRC56-65, the highest hardness of Chromium Carbide can be HV1800.
WEAR RESISTANCE: According to lab test for wear resistance, WALDUN chrome carbide overlay steel is 20 times that of low carbon steel. And 8 times that of heat treated wear resistant steel. Test data of surface wear resistance and 75% depth wear resistance of ASTM-G65A dry sand show that it has high wear resistance.
Chromium carbide overlay plate flatness: flatness control in ±3mm/M.
Chromium carbide overlay plate thickness : alloy layer thickness uniformity, thickness tolerance 0-0. 5 mm.
Other thickness chromium carbide wear plates can also be customized, welcome to inquiry.

Production Capacity

Quality Control

WALDUN has experienced a quality inspection team with material science bachelor-degree and the leaders with material science master-degree. Our inspection team makes regular testing on raw material, production process, and our products according to our company’s strict regulation.

In our laboratory, WALDUN uses Rockwell hardness tester, portable spectrum, portable hardness tester, and portable ultrasonic thickness measurement instrument to make sure of overlay plates quality.

There are also abrasion resistance testing machine and a series of metallography experiment instruments, so the metallurgical microstructure and wear resistance can be tested.

Safe Packing

WALDUN can provide steel pallet design or product the steel pallet according to your drawing so that chromium carbide overlay plate can be safely supported and easily transported with a steel tape and iron Ecke.

Packaging: Steel pallet, Non-fumigation pallets, Plastic Film.

Packaging Size: 1.4*3.4 m, 1.4*.3.0 m, 1.4*3.5 m, 2.1*3.5 m. Other sizes can be customized.

Delivery Detail: Generally, it is 5-10 days if the goods are in stock. Or it is 15-20 days if the goods are not in stock, it is according to quantity.

It can be Loaded into 20 ft or 40 ft container.

Comparison With Normal Wear Plate

The content of chromium in the chemical composition of wear-resistant layer is as high as 25 ~ 40%; The content of chromium in common wear-resistant plate is only 10 ~ 20%.

The volume fraction of Cr7C3 carbide in metallographic structure is more than 50%; The volume fraction of ordinary wear-resistant plate is less than 30%.

The hardness of wear-resistant layer is high and uniform. The hardness is HRC60-65; The hardness of the ordinary wear-resistant plate is not uniform, and the hardness is less than 60.

The thickness of wear-resistant layer is uniform and the tolerance is controlled between 0 ~ 0.5 mm; Ordinary wear-resistant plate wear-resistant layer thickness is mostly uneven.

The flatness and flatness of the plate surface are controlled at 3mm/M; The common wear-resistant plate is uneven and seriously deformed.

Wear resistance is 5 to 6 times higher than heat treatment wear-resistant Steel; Ordinary wear-resistant plate wear resistance is poor or no wear resistance.
