Advantages of Overlay Wear Plate

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.

Extended Equipment Lifespan​

By ​​withstanding extreme abrasion, impact, and sliding friction​​, overlay plate minimizes material loss, reducing the frequency of plate replacements and lowering long-term operational costs for heavy machinery.

Customizable Hardness & Composition​

Available in ​​multiple grades (AR400, AR500, chrome carbide, or nickel-based alloys)​​, overlay plate can be tailored to specific applications—whether for ​​crushing, dredging, or steel mill slag handling​​—ensuring optimal performance.

Cost-Effective Wear Solution​

Compared to replacing entire worn components, ​​overlay plate’s durable cladding extends the life of base steel structures (like carbon steel substrates) by 3–5x​​, delivering significant savings in maintenance and downtime.

FAQ

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.
Hard facing plate for coal chute liner is usually attached by countersunk bolts, welding studs, perimeter welding, or plug welding. Some methods are better suited than others depending on the specific application. For more detail on each method see the installation section.
Hard facing plate for coal chute liner cannot be machined or drilled. It can however be ground. Mild steel inserts are used to create countersunk or counter bored holes. hard facing plate for coal chute liner can be cut using plasma, Grinding wheel saw, or air-arc gouging.
Our product has no limit to quantity, it can be ordered according to customer requirement.

What Our Clients Are Saying

​​Lisa K.
​​Lisa K.

We’ve been using overlay wear plate for our crusher liners for two years—zero cracks, minimal wear, and it outlasts standard steel by at least 4x. Best investment for our high-abrasion operation.

Our dredge pipes face sand, saltwater, and constant abrasion—overlay plate’s hardfacing layer keeps them intact far longer than regular steel. No rust or flaking either!
