Tấm phủ mối hàn: How Price Relates to Overlay Thickness and Chemical Composition
Weld overlay plate is a composite wear-resistant steel plate produced by depositing a hard alloy layer onto a carbon steel or low-alloy steel base through welding technology. Its performance and cost are mainly determined by two key factors: độ dày lớp phủ Và chemical composition of the weld layer.
Đúng, the welding layer composition is directly related to the price, because it determines material cost, độ cứng, chống mài mòn, and production complexity.
1. Why Weld Overlay Plate Price Varies
| Yếu tố chi phí | Impact on Price |
|---|---|
| Thành phần hợp kim | Higher Cr, C, Nb, Mo, W increases cost significantly |
| Độ dày lớp phủ | Thicker layers require more welding material and time |
| Welding process | PTA, laser cladding cost more than open arc welding |
| Hardness requirement | Higher hardness requires more complex alloy design |
| Quality control | Strict inspection increases production cost |
2. Relationship Between Overlay Thickness and Cost
| Độ dày lớp phủ | Typical Cost Level | Ứng dụng |
|---|---|---|
| 3–4 mm | Thấp hơn | Light abrasion conditions |
| 5–6 mm | Trung bình | Quần áo công nghiệp nói chung |
| 7–8 mm | Cao hơn | Môi trường mài mòn nghiêm trọng |
| 10 mm+ | Highest | Điều kiện mài mòn khắc nghiệt |
Thicker overlay layers require more welding passes and more alloy consumption, directly increasing cost.
3. Relationship Between Chemical Composition and Price
| Alloy Type | Các yếu tố chính | Mức chi phí |
|---|---|---|
| Standard chromium carbide overlay | Fe + C + Cr (20–30%) | Tiết kiệm |
| High-chromium complex alloy | Cr + C + Mo + Nb | Trung bình |
| Tungsten carbide reinforced | nhà vệ sinh + Ni/Fe matrix | Cao |
| Lớp phủ gốc niken | TRONG + Cr + B + Và | High to very high |
Higher alloy content improves wear resistance, chống ăn mòn, and heat resistance, but also increases raw material and processing cost.
4. Thickness vs Composition: Which Matters More?
- độ dày: Determines service life and wear allowance
- Thành phần: Determines hardness and wear mechanism
- Both together: Define final performance and price level
Trong hầu hết các trường hợp, alloy composition has a greater impact on performance, while thickness mainly affects service life duration.
5. Why Better Composition Costs More
- Higher alloy cost (Cr, Nb, W, TRONG)
- More complex welding control
- Lower production speed
- Tighter quality requirements

Phần kết luận
Đúng, weld overlay plate price is directly affected by both overlay thickness and chemical composition. Thickness determines how long the plate lasts, while alloy composition determines how well it resists wear. The best solution is always a balance between cost and working condition.
