Chromium Carbide Cladding Plate: Overlay Composition and Performance

Chromium carbide cladding plate, also known as chromium carbide overlay plate or hardfacing wear plate, is a composite wear-resistant steel plate designed for extreme abrasion environments. It is manufactured by depositing a high-hardness chromium carbide alloy layer onto a mild steel or low-alloy steel substrate through automatic open-arc or submerged arc welding.

The core value of chromium carbide cladding plate lies in its overlay layer, where high chromium carbide content provides outstanding resistance to abrasive wear, sliding wear, and erosion.

1. Structure of Chromium Carbide Cladding Plate

Layer	Main Function
Chromium carbide overlay layer	Main wear-resistant working surface
Base plate	Provides structural strength and weldability

The overlay layer is the most critical part because it directly determines wear resistance and service life.

2. Typical Chemical Composition of Overlay Layer

Element	Typical Content (%)	Function
Carbon (C)	3.0–5.0%	Forms hard carbide phases
Chromium (Cr)	20–35%	Creates chromium carbide particles
Iron (Fe)	Balance	Main matrix material
Other alloy elements	Small amount	Improve toughness and wear performance

3. Microstructure of Overlay Layer

The overlay layer mainly consists of:

Primary chromium carbides (M7C3): Extremely hard wear-resistant particles
Alloy matrix: Supports carbide particles and absorbs stress

This carbide-rich microstructure gives chromium carbide plates excellent wear resistance in high-abrasion environments.

4. Key Performance Characteristics

Property	Performance
Overlay hardness	HRC 58–65
Abrasion resistance	Excellent
Impact resistance	Moderate
Heat resistance	Good in moderate high-temperature wear conditions
Service life	5–8× longer than ordinary steel

5. Why Overlay Composition Matters

Higher chromium content: Increases carbide formation
Higher carbon content: Improves hardness and wear resistance
Balanced matrix structure: Prevents brittle failure
Proper alloy design: Improves service life under real working conditions

6. Common Applications

Industry	Application
Mining	Crusher liners, hoppers, chutes
Cement	Fans, cyclones, ducts
Power plants	Coal pipes, ash systems
Steel plants	Material conveying systems
