Cobalt Based Hardfacing Plate: What Materials Are Used for the Base Plate?

Cobalt based hardfacing plate is a premium composite wear-resistant plate manufactured by depositing a cobalt-based alloy overlay onto a steel substrate through welding or cladding technology. This type of hardfaced plate is mainly used in severe wear environments involving high temperature, corrosion, oxidation, and metal-to-metal wear.

While the cobalt-based overlay layer determines wear and heat resistance, the base plate material is equally important because it provides structural support, toughness, and weldability.

1. Structure of Cobalt Based Hardfacing Plate

Layer	Main Function
Cobalt-based overlay layer	Wear, heat, and corrosion resistance
Base plate	Strength, support, and fabrication performance

The base plate acts as the load-bearing component, while the overlay layer protects against wear.

2. Common Base Plate Materials

Different base materials are selected according to operating conditions and fabrication requirements.

Base Plate Material	Main Characteristics	Typical Use
Carbon steel (Q235 / ASTM A36)	Low cost, excellent weldability	General industrial use
Low alloy steel (Q345 / ASTM A572)	Higher strength and toughness	Heavy-duty structural parts
Stainless steel (304 / 316)	Corrosion resistance	Chemical and corrosive environments
Heat-resistant steel	High-temperature stability	Thermal wear applications

3. Why Base Plate Material Matters

Factor	Impact
Strength	Determines load-bearing capability
Toughness	Improves crack resistance
Weldability	Affects fabrication efficiency
Heat resistance	Important in high-temperature service

Selecting the wrong base plate can reduce overall service life even if the overlay layer is highly wear resistant.

4. Why Cobalt-Based Overlay Is Special

Cobalt-based overlays are typically chosen for conditions where wear occurs together with heat and corrosion.

Excellent thermal stability
Outstanding oxidation resistance
Good metal-to-metal wear resistance
Strong resistance to thermal fatigue

5. Common Applications

Industry	Application
Power plants	High-temperature wear components
Steel plants	Thermal wear systems
Oil & gas	Corrosion + wear environments
Chemical plants	Corrosive process equipment
