High Temperature Resistant Overlay Plate

Wear-resistant composite steel plate produced by our company is built-up welding on ordinary steel plate,  form an alloy wear-resistant layer with a volume fraction of more than 50% Cr7C3 carbide. It has the characteristics of high wear-resistant, impact-resistant and easy to process, widely used in mining, cement, steel, power and other industries.

• The cement industry: pipelines, vibrating screens, pump shell and others.
• The power industry: mills, conveyors, discharge pipes and others.
• The steel industry: vibrating screen, tanks, rod pillars and others.
• The paper industry: spiral conveyor, transition elbow, cyclone lining and others.
• The mining industry: cover plate, wear rod,  wear plate and hopper line.
• The coal industry: pump bodies, coal pipes,and others.

According to your customized drawings, WALDUN can manufacturer the wear plates for cutting, bending, curling, tailor-welded production into the required parts.

• WEAR PLATE PRODUCTION LINE: 20 LINES.
• Process: Open ARC process.
• Yield: 90000 square meters.
• C content of wear-resistant layer (%) : 3 ~ 5.5% .
• Cr content (%) : 25 ~ 40% .
• HRC: 58-65.
• CR7C3 CARBIDE VOLUME FRACTION: above 50% .

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.

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.

• 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.
