Advantages of Chromium Carbide Overlay Welding

Unmatched Wear Resistance

Engineered substrates are eight times more resistant to scratching and abrasion in high-silicon environments (such as mining conveyors) than quenched steel.

Corrosion Resistance in Harsh Environments

Resistant to acids, alkalis, and oxidizing agents—suitable for chemical processing (e.g., sulfuric acid slurry treatment).

Thermal Stability Under Extreme Temperatures

Maintains a hardness of 58+ HRC at 1,200°F (650°C) without spalling—critical for boiler tubes and kiln linings.

Impact-Resistant High-Strength Bonding

Micro-crack structures absorb kinetic energy and prevent fractures from occurring under repeated hammering (e.g., wear-resistant plates in crushers).

Chromium Carbide Hardfacing Welding Overlay Wear Liner

Overview:

Chromium Carbide Hardfacing Welding Overlay Wear Liner the chemical composition of the high wear resistance alloy layer contains 4 to 5% carbon and 25 to 30% chromium.

The volume fraction of Cr7C3 carbide in the metallographic structure reaches more than 50%, and the macro hardness is HRC58 to 63.

The hardness of chromium carbide is HV1400 ~ 1800, which is higher than the hardness of quartz in sandstone HV800 ~ 1200.

Since carbides are distributed vertically in the direction of wear, even when compared with casting alloys of the same composition and hardness, the wear resistance is more than doubled.

FAQ

MOQ?

Our product has no limit to quantity, it can be ordered according to customer requirement.

How is chromium carbide coating applied to building components?

Chromium Carbide Overlay is typically applied using a welding process, where a layer of chromium carbide is fused to the base material to create a wear-resistant surface.

Why are there so many cracks?

Due to the cooling rates of dissimilar metals. Our hard facing plate for coal chute liner is manufactured by welding which results in high temperatures. During the cooling, the plate goes through a stress relieving which is a natural process and does not effect the performance of the plate. The stress relief cracks should be between 3/4" - 2" apart. The cracks can be touched up by our chrome carbide welding rod.

How can I ensure the quality of Chromium Carbide Overlay construction parts?

It is important to source Chromium Carbide Overlay parts from reputable manufacturers who use high-quality materials and adhere to strict quality control standards.

What Our Clients Are Saying

Mark Rodriguez

The kiln lining was constantly wearing out and causing shutdowns, but after using this company's CCO plates, there have been no shutdowns in six months, and production efficiency has increased by 20%!

Alex K.

The hot-rolled rollers are completely covered with steel slag, and the chromium carbide coating withstands temperatures of 1200°C, reducing the number of liner replacements by 10 times per year!
