Hardfacing Processed Plate
Hardfacing Processed Plate for Custom Wear Liners, Chutes, Hoppers, Pipes, Buckets, and Industrial Wear Parts
HALDEN hardfacing processed plate is made by depositing a highly abrasion-resistant weld overlay onto a mild steel base plate using open arc welding. The overlay can be supplied in one or two layers and processed into custom wear parts by cutting, bending, welding, forming, drilling, and fabrication according to customer drawings.
Most Wear Problems Are Not Solved by Flat Plate Alone — They Need Processed Liners That Fit the Actual Equipment.
HALDEN hardfacing processed plates can be cut, bent, welded, and fabricated into practical wear parts for severe abrasion and moderate impact service.
Key Information Needed Before Ordering Hardfacing Processed Plate
To process wear plates correctly, HALDEN needs the drawing, part dimensions, base plate thickness, overlay thickness, bending direction, hole positions, installation method, working condition, material handled, and whether the part needs cutting, bending, rolling, drilling, countersinking, plug-weld holes, or welded assembly.
Plate Structure
The plate consists of a mild steel base plate and one or two layers of abrasion-resistant open arc weld overlay.
Processing Method
Plates can be processed by cutting, bending, welding, forming, drilling, and other recommended methods.
Wear Environment
Ore, coal, clinker, slag, limestone, ash, sand, and other abrasive materials create different liner design requirements.
Installation Design
Bolt-on, plug-weld, studded, direct-weld, and welded assembly designs require different hole and edge preparation.
What Is a Hardfacing Processed Plate?
A hardfacing processed plate is a chromium carbide overlay wear plate that has been cut, bent, drilled, welded, or fabricated into a specific wear-resistant component. Instead of supplying only standard flat plates, HALDEN processes the plate into liners, chute sections, hopper parts, pipe sections, bucket liners, feeder liners, and custom wear assemblies according to drawings.
Mild Steel Base Plate
The backing plate provides toughness, weldability, and practical installation support for fabricated wear parts.
Abrasion-Resistant Overlay
The hardfacing overlay is deposited by open arc welding and can be supplied as one or two layers depending on wear severity.
Custom Wear Part Shape
The plate can be processed into various shapes for equipment-specific wear protection and easier installation.
Technical Features of HALDEN Hardfacing Processed Plate
The original page highlights transverse stress-relief cracks, metallographic structure, HRC56–62 hardness, chromium-rich overlay, and good processing capability.
| Feature | Technical Meaning | Buyer Value |
|---|---|---|
| Open Arc Weld Overlay | A highly abrasion-resistant welded overlay is deposited onto the mild steel base plate. | Provides strong protection against sliding abrasion and bulk material wear. |
| One or Two Overlay Layers | Overlay deposit can be supplied as one layer or two layers. | Allows plate selection by wear life target and service severity. |
| Transverse Stress-Relief Cracks | Cracks occur naturally during welding due to stress release and are controlled by chemistry or cooling methods. | These cracks are normal for hardfacing wear plate and do not affect wear plate performance. |
| HRC56–62 Hardness | The compound wear plate can reach HRC56–62 depending on specification. | Supports excellent wear resistance in abrasive working conditions. |
| Alloy Flexibility | Besides chromium, elements such as manganese, molybdenum, niobium, and vanadium can be included for different applications. | Makes the overlay adaptable to different wear environments and performance requirements. |
Main Advantages
Hardfacing processed plate is used when buyers need both abrasion resistance and practical fabrication into equipment-ready wear parts.
Flat and Smooth Surface
A controlled overlay surface helps support liner fit-up, installation, and material flow behavior.
Outstanding Wear Resistance
Chromium-rich hardfacing overlay helps protect equipment surfaces from severe abrasive wear.
Economical Production Cost
Processed wear plate helps reduce site fabrication work and makes liner replacement more efficient.
Various Wear Part Shapes
The plate can be processed into different shapes for hoppers, chutes, pipes, buckets, bins, and custom equipment surfaces.
Moderate Impact and Good Temperature Resistance
Suitable for abrasive applications with moderate impact and temperature exposure within the selected alloy capability.
Good Weldability to Structural Steel
The mild steel base plate can be welded to most structural steel, making installation and fabrication practical.
Hardfacing Processed Plate Specifications
The original specification data is preserved below and formatted for easier buyer review. Thickness and size can also be customized according to customer requirements.
| Plate Spec | Base Plate | Overlay | Hardness | Standard Size |
|---|---|---|---|---|
| 10mm / 6+4 | 6mm | 4mm | HRC54–58 | 2000×1200mm / 1500×3000mm / customized |
| 12mm / 6+6 | 6mm | 6mm | HRC56–60 | 2000×1200mm / 1500×3000mm / customized |
| 14mm / 8+6 | 8mm | 6mm | HRC56–60 | 2000×1200mm / 1500×3000mm / customized |
| 18mm / 10+8 | 10mm | 8mm | HRC56–62 | 2000×1200mm / 1500×3000mm / customized |
| 16mm / 12+4 | 12mm | 4mm | HRC54–58 | 2000×1200mm / 1500×3000mm / customized |
Processing and Fabrication Options
HALDEN can process hardfacing plates into ready-to-install wear parts according to drawings and site installation requirements.
Cut-to-Size Wear Liners
Plates can be cut into rectangular, trapezoid, curved, segmented, or irregular liner shapes.
Bending and Forming
Processed plates can be formed for chute walls, hopper cones, feeder liners, bin liners, and curved wear surfaces.
Drilling and Hole Preparation
Bolt holes, countersunk holes, plug-weld holes, lifting holes, slots, and special fixing patterns can be prepared.
Welded Wear Assemblies
HALDEN can fabricate wear plates into hoppers, pipes, elbows, boxes, chute sections, bucket liners, and complex wear packages.
Important Note: Transverse Surface Cracks Are Normal Stress-Relief Cracks
During hardfacing, transverse cracks can appear naturally on the overlay surface because the hard alloy layer releases welding stress. These cracks are controlled by overlay chemistry or cooling methods and do not reduce the wear plate performance when the plate is properly manufactured.
Typical Applications of Hardfacing Processed Plate
Hardfacing processed plates are used in industrial equipment where flat plate must be converted into a specific wear-resistant shape.
Hardfacing Processed Plate Selection Guide
The correct specification should be selected by wear severity, impact level, processing requirement, base plate thickness, overlay thickness, and installation method.
| Requirement | Recommended Direction | Buyer Note |
|---|---|---|
| Light to medium abrasion | 6+4 or 12+4 processed plate | Useful when a thinner overlay is enough and processing flexibility matters. |
| Higher abrasion service | 6+6, 8+6, or 10+8 processed plate | More overlay thickness supports longer wear life in severe sliding abrasion. |
| Need bending or forming | Confirm bend direction and radius before production | Overlay direction, crack direction, and base thickness affect forming performance. |
| Need bolt-on installation | Pre-drilled or countersunk wear liners | Send hole pattern drawing to avoid site rework. |
| Need welded assembly | Processed plates with mild steel base welding design | Base plate weldability supports assembly into hoppers, chutes, boxes, and custom wear parts. |
Quality Control Points
For processed wear plate orders, both material quality and processing accuracy must be controlled before shipment.
