Chrome Carbide Plate: Cutting and Bending Process of Overlay Wear Plate

Chrome carbide plate (크롬 카바이드 오버레이 마모 플레이트) is a bimetallic composite material with a hard wear-resistant overlay layer deposited on a mild steel or low-alloy steel base. Because of its extremely high surface hardness (typically HRC 58–65), its cutting and bending processes are very different from ordinary steel plates.

Proper processing methods are essential to avoid cracking, edge chipping, and damage to the carbide layer.

1. Why Chrome Carbide Plate Is Difficult to Process

요인	Impact on Processing
High hardness overlay layer	Cannot be cut with standard mechanical tools
Brittle carbide structure	Prone to edge cracking under impact
Bimetal structure	Different thermal expansion between layers
Residual welding stress	Requires controlled cutting and bending

2. Cutting Methods of Chrome Carbide Plate

(1) 플라즈마 절단

• Most common industrial method
• Suitable for medium-thickness plates
• Fast and cost-effective

(2) Waterjet Cutting

• 열영향부 없음
• Best for high-precision parts
• Prevents micro-cracking of carbide layer

(3) 레이저 절단

• 고정밀 절단
• 얇은 오버레이 플레이트에 적합
• Requires strict parameter control

(4) Abrasive Wheel Cutting

• Used for simple straight cuts
• Lower cost but slower process
• Higher risk of edge wear

3. Key Cutting Precautions

• Avoid overheating to prevent carbide layer damage
• Control cutting speed to reduce cracking risk
• Use proper fixturing to avoid vibration
• Allow stress relief after cutting if needed

4. Bending Process of Chrome Carbide Plate

Bending is more challenging than cutting because the hard overlay layer has low ductility.

방법	Applicability
Cold bending	Limited to small angles and thin plates
Hot bending (controlled heating)	균열 위험 감소
Rolling forming	Suitable for large-radius curves

5. Bending Limitations

• Small bending radius is not recommended
• Excessive bending may cause surface cracking
• Overlay layer is less ductile than base steel

대부분의 경우, design optimization is preferred over heavy deformation processing.

6. Best Practice: Fabrication First Design

To reduce processing difficulty and cost, engineers often design wear parts considering:

• Straight plate assembly instead of deep bending
• Segmented liners instead of single curved parts
• Welded modular structures
