Wear Plate for Abrasion, Impact and Material Flow

JINHUA manufactures hardfacing wear plates for equipment exposed to continuous abrasion, sliding wear and material erosion. Rather than selecting a wear plate by hardness alone, we recommend matching the overlay and total plate thickness to the actual operating condition.

Common applications include chutes, hoppers, crusher liners, bucket liners, transfer points, pipe sections and other surfaces exposed to ore, clinker, coal, sand and similar abrasive materials.

For a new project, send us the material handled, equipment position, impact condition, operating temperature and required service life. We can then review the required plate construction before quotation.

How to Select the Wear Plate Thickness

Wear plate thickness is normally specified as the base plate thickness plus the hardfacing overlay thickness.

For example:

3+3
A thinner backing plate with a thinner overlay. It is generally considered where space and overall component weight are limited and the wear allowance required is relatively small.

6+6
Provides a greater wear allowance and is suitable for many liners and wear surfaces exposed to continuous abrasive material flow.

8+8 / 10+10 / 12+12
Used where a thicker wear layer or heavier plate construction is required for severe service.

The thickest plate is not automatically the best choice.

Before production, the selection should consider:

• Wear rate

• Impact level

• Material particle size

• Material drop height

• Operating temperature

• Existing liner thickness

• Equipment clearance

• Expected maintenance interval

If an existing liner is being replaced, send the current plate specification and working-life record. This gives us a more useful starting point than selecting only by total thickness.

Hardfacing Wear Plate vs. Wear-Resistant Steel Plate

These two products are often searched together, but they are not the same material.

Hardfacing Wear Plate

A hard alloy overlay is welded onto a tougher steel backing plate. The overlay provides the main abrasion resistance while the backing plate supports fabrication and installation.

It is commonly considered for severe sliding abrasion and material-handling surfaces where wear occurs mainly at the equipment surface.

Quenched and Tempered Wear-Resistant Steel Plate

AR-type steel such as AR400 or AR500 is wear resistant throughout the plate rather than having a separate welded overlay.

It is commonly selected where wear resistance needs to be combined with higher impact resistance and where conventional steel fabrication methods are important.

For equipment exposed mainly to severe abrasion, a hardfacing wear plate can provide a much harder working surface.

Where heavy impact is the dominant failure mode, the application should be reviewed before choosing an overlay plate.

Send us the wear location and operating condition if you are deciding between an overlay wear plate and a conventional abrasion-resistant steel plate.

Hardfacing Techniques

Flux‑Cored Arc Welding (FCAW)

FCAW is the predominant method for depositing wear-resistant overlays on wear plates. This technique enables high deposition rates, which helps in building a thick and consistent hardfacing layer quickly.

Submerged‑Arc Welding (SAW)

For large plates or very thick overlay layers, SAW is often employed due to its deep penetration and high deposition efficiency. This makes it cost-effective for heavy-duty and large-scale wear-resistant plate production.

Multi‑Pass Overlay Welding

Multiple welding passes are typically used to achieve the required overlay thickness. Controlling the heat input and interpass temperature is essential to ensure a homogeneous hardfacing layer and to minimize dilution or cracking.

Stress‑Relief / Cross‑Check Cracking

As the overlay cools, a network of micro‑cracks (also known as cross‑check cracks) often forms. Contrary to being defects, these cracks help relieve internal stresses and contribute to better performance under impact or thermal cycling.

Cutting & Fabrication

After the hardfacing layer is welded, the wear plates can be cut, formed, or fabricated using common industrial methods such as plasma cutting, water‑jet cutting, or laser cutting. This customization allows wear plates to fit specific machinery geometries.

Hardfacing Materials

Chromium‑Carbide (Cr‑C) Alloys

Chromium‑carbide overlay is the most common material for wear plates. The Cr–C alloy forms carbide phases (such as Cr₇C₃) that provide very high hardness and excellent resistance to abrasive wear.

High‑Chromium / High‑Carbon Alloys

Alloys with elevated chromium and carbon content are used to create very hard microstructures. These materials are suited for environments with severe abrasion.

Complex Carbide Systems

For even more demanding wear applications, overlay alloys may include additional elements (e.g., niobium, vanadium, titanium) to form complex carbides. These carbides enhance resistance to erosion, sliding abrasion, and long-term wear.

Ductile Buffer or Transition Layers

To reduce brittleness and improve the toughness of the overlay, a graded or layered design can be used: a more ductile layer near the steel base plate is followed by a hard, carbide-rich surface layer. This helps balance wear resistance and impact tolerance.

Thermal Stability & High‑Temperature Alloys

For applications that involve elevated temperatures, alloy formulations can be tuned to maintain hardness at high temperatures, ensuring long-term stability of the overlay.

Matching Techniques with Materials for Wear Plates

If the wear plate is subject to severe abrasion, then thick chromium‑carbide overlays deposited by FCAW or SAW are highly effective.

For zones with impact + abrasion, using a layered overlay (tough base + hard surface) and controlled crack patterns helps absorb shock while maintaining surface hardness.

In high-temperature environments, selecting alloy systems that retain hardness under thermal load is critical for long-lasting wear protection.

For custom parts and shapes, hardfaced plates can be pre-welded and then cut to specification, giving flexibility in design and installation.

Key Advantages of High‑Quality Wear Plates

Extended Service Life — Overlay layers with high carbide content significantly slow down wear, greatly extending the lifetime of base components.

Reduced Maintenance Costs — By using wear plates, you avoid frequent part replacement, leading to cost savings over time.

Improved Reliability — Properly designed overlays (with microstructure control and crack-relief) deliver consistent performance even under severe operating conditions.

Customization — Wear plates can be manufactured in various sizes, shapes, and grades to match specific equipment and wear profiles.

Wear Plate/Abrasion Resistant Wear Plate/Wear Resistance Plate

Clad welding wear resistance plates are high-performance metal plates designed to withstand extreme wear and tear in industrial and mining applications. These plates are made by welding a layer of wear-resistant material onto a base material, creating a durable and long-lasting product that can withstand harsh operating conditions.

JINHUA tungsten carbide covered wear plate, a unique chromium carbide covered plate, is located on a mild steel base. Its excellent wear resistance and abrasion resistance ensures longer equipment life while reducing maintenance costs.

Produced using a unique and versatile automated batch welding method, tungsten carbide covered wear plates are made from the highest quality raw materials and offer superior wear resistance and high durability compared to mild steel. Our fully automated production methods and quality control procedures ensure that the product has uniform chemical analysis and hardness throughout the composite layer.

The base material used is primarily carbon steel, which allows the final product to be easily welded and formed in complex structures. Other steels can be used as substrates, including stainless steel, AR and other special steels as required by the customer in specific applications.

Plates and fabrications offer excellent wear resistance and can be easily installed on all types of equipment, extending their service life while providing cost-effective protection.JINHUA's design, fabrication and manufacturing expertise ensures an increased return on your wear investment, thus giving you peace of mind.

Wear resistance plates are considered one of the most important things that manufacturing and industrial companies need. If you own one, then you have probably considered using wear plates; but what are they really for?
