Nickel Based Overlay Plate: How Its Overlay Layer Differs from Other Cladded Wear Plates

Nickel based overlay plate is a special type of hardfaced composite steel plate in which the wear-resistant overlay layer is primarily composed of nickel-based alloy materials. Compared with traditional chromium carbide or tungsten carbide overlay plates, nickel-based overlay plates are designed not only for wear resistance but also for excellent corrosion resistance, oxidation resistance, and high-temperature stability.

This makes nickel-based overlay plates particularly suitable for severe working environments involving high heat, corrosive chemicals, and combined wear-corrosion conditions.

1. What Is the Overlay Layer of Nickel Based Overlay Plate?

The overlay layer is typically deposited onto carbon steel or low-alloy steel substrates through welding or cladding processes.

Layer	Main Function
Nickel-based alloy overlay	Wear, corrosion, and heat resistance
Base plate	Structural strength and weldability

Unlike carbide-based overlays that mainly focus on abrasion resistance, nickel-based overlays offer broader performance advantages.

2. Typical Composition of Nickel-Based Overlay Layer

Element	Main Function
Nickel (Ni)	Main alloy matrix, corrosion resistance
Chromium (Cr)	Oxidation and corrosion resistance
Boron (B)	Improves hardness
Silicon (Si)	Improves alloy flow and wear performance
Optional carbides	Improves wear resistance

3. Key Differences vs Other Overlay Plates

Overlay Type	Main Advantage	Main Limitation
Nickel-based overlay	Heat + corrosion + wear resistance	Higher cost
Chromium carbide overlay	Excellent abrasion resistance	Lower corrosion resistance
Tungsten carbide overlay	Extreme wear resistance	Lower toughness, expensive
Complex carbide overlay	Balanced wear resistance	Limited heat resistance

4. Performance Comparison

Property	Nickel-Based Overlay	Carbide Overlays
Abrasion resistance	Good	Higher
Corrosion resistance	Excellent	Lower
Heat resistance	Excellent	Moderate
Oxidation resistance	Excellent	Moderate

5. Why Nickel-Based Overlay Is Special

Better chemical resistance: Performs well in corrosive environments
High-temperature stability: Maintains properties under heat
Strong oxidation resistance: Suitable for thermal wear conditions
Multi-functional protection: Combines wear and corrosion resistance

6. Common Applications

Industry	Application
Chemical plants	Corrosion-resistant equipment lining
Power plants	High-temperature wear components
Oil & gas	Corrosive wear equipment
Steel plants	Thermal wear systems
