Bimetallic Hardfaced Plate: Material Introduction of Composite Overlay Wear Plate

Bimetallic hardfaced plate is a composite wear-resistant steel plate made by combining two different metallic materials: a tough base plate and a high-hardness overlay layer. It is designed to provide both structural strength and excellent wear resistance in severe abrasion environments.

This type of wear plate is widely used in mining, cement, steel, power generation, and bulk material handling industries where equipment surfaces are exposed to heavy wear and impact.

1. What Is a Bimetallic Hardfaced Plate?

The term “bimetallic” means the plate consists of two functional metal layers bonded together through welding technology.

Layer	Material Type	Main Function
Overlay layer	High-alloy hardfacing material	Provides wear resistance
Base plate	Mild steel / low alloy steel	Provides strength and toughness

This composite structure combines the best properties of both materials.

2. Common Base Plate Materials

The base plate provides structural support and determines the plate’s weldability and toughness.

Base Material	Main Characteristics
Q235 / Mild Steel	Good weldability, economical
Q345 / Low Alloy Steel	Higher strength and better toughness
Wear-resistant steel (NM400/NM500)	Improved impact resistance

3. Common Overlay Layer Materials

The overlay layer is the working surface that resists abrasion and wear.

Overlay Material	Main Feature	Application
Chromium carbide alloy	Excellent abrasion resistance	Mining, cement
Complex carbide alloy	Higher wear resistance	Extreme wear conditions
Tungsten carbide overlay	Ultra-high hardness	Severe abrasion environments

4. Typical Chemical Composition of Overlay Layer

Element	Typical Range	Function
Carbon (C)	3–5%	Forms hard carbides
Chromium (Cr)	20–35%	Creates chromium carbides
Iron (Fe)	Balance	Main alloy matrix
Other alloys	Optional	Improve toughness and wear resistance

5. Key Performance Characteristics

Property	Performance
Overlay hardness	HRC 58–65
Abrasion resistance	Excellent
Impact resistance	Depends on base material
Weldability	Good on base plate side
Service life	Several times longer than standard steel

6. Why Bimetallic Design Is Effective

Hard surface: Protects against severe wear
Tough substrate: Prevents cracking and structural failure
Long service life: Reduces downtime and replacement cost
Flexible design: Can be customized for different wear conditions

7. Common Applications

Industry	Application
Mining	Chutes, liners, crushers, hoppers
Cement	Fans, cyclones, ducts
Power plants	Coal handling systems
Steel plants	Material transfer systems
