Advantages of Hardfacing Plate

Extreme Abrasion Resistance

Engineered with 50-65% chromium carbides, our hardfacing plates achieve 58-65 HRC surface hardness – delivering 8-15X longer lifespan than AR400 steel in high-wear zones like raw mill feed chutes and slag conveyors.

Impact-Resistant Toughness

A ductile low-carbon steel backing (Q235/Q345) absorbs heavy impact shock, while the metallurgically bonded overlay prevents cracking – proven in mining crusher liners and shovel buckets subjected to 12-ton rock impacts.

Custom Thickness & Geometry

Available in 4+4mm to 30+20mm configurations with waterjet-cut bolt holes, radii, and contours – eliminating post-weld machining and reducing installation time by 70% for complex equipment like cyclone separators.

Cost-Per-Ton Dominance

Reduce total operating costs by 40-60% versus replaceable liners: our hardfacing plates slash downtime for change-outs and eliminate consumable welding rods in high-abrasion zones like coal pulverizer cones.

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.

What is the best method of attachment?

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.

Can hard facing plate for coal chute liner be drilled or machined?

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.

MOQ?

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

What Our Clients Are Saying

Lisa K.

Our transfer chutes used to eat through AR400 plates every 3 months. After switching to these chromium carbide hardfacing plates, we’ve gone 18 months without replacement – saving $217,000 in downtime alone.

Rajiv Patel

Installed these 15+10mm hardfacing plates in our raw mill feed chute. The directional carbide overlay withstood limestone abrasion at 500 tph for 14 months – 3X longer than our previous welded solution.

Sarah MacKenzie

No more weekly weld repairs! These plates’ metallurgical bonding survived 12 months of granite impact loading in our primary crusher. Our consumable welding rod costs dropped by 82% last quarter.

Michael Torres

Coal pulverizer wear was shutting us down monthly. Since installing these ASTM G65-tested hardfacing plates, we’ve achieved 11 months of continuous operation – and avoided $360k in lost generation revenue.
