Chromium Carbide Overlay Plate Suppliers Wear-Resistant Steel for Industrial Use

The annual sales volume of composite plate welding wire is nearly 3,000 tons, occupying a high market share in China. With stable quality and high-quality service, the domestic sales volume and export volume are increasing year by year.

Wear plates manufactured by welding one or multiple wear resistant layers on a medium or low carbon steel base plate.

The overlay alloy has a high amount of chromium carbide hard particles which makes the plate have good wear and impact resistance.

When are overlay products the best choice?
There are many abrasive situations where overlay plates are the most suitable material, both from a technical and cost perspective. The following are some examples:

• Sliding and moderate impact wear from hard minerals in small size, such as gravel, slurry, and sand with quartz content.
• Sliding wear from larger rocks or impact where rocks are brittle and easy crushable, such as sandstone, limestone, and coal.
• Sliding wear in a wet environment, such as from slurry and dredging operations
• When processing fine particles that cause erosion.

Even if 95% of an abrasive rock is made up of soft minerals, the remaining 5% can be very hard and contribute to 90% of the wear – thus making overlays the best solution.

Characteristics of products

(1) 20- 25 times harder than low carbon steel

(2) 5-20 times harder than high manganese steel

(3) 5-10 times harder than tool steel

(4) 1.5-2.5 times harder than high-chromium steel

Application

The Chromium Carbide Overlay Plate finds extensive use in mining equipment, such as drilling bits, cutters, and excavators. Its ability to withstand the demanding conditions of mining environments makes it a popular choice among professionals in the industry. Additionally, its wear resistance and corrosion resistance make it suitable for use in construction equipment, such as bulldozers and backhoes, where it helps extend the lifespan of critical components.
