Pelat Hamparan Las: 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: ketebalan lapisan atas Dan chemical composition of the weld layer.
Ya, the welding layer composition is directly related to the price, because it determines material cost, kekerasan, ketahanan aus, and production complexity.
1. Why Weld Overlay Plate Price Varies
| Faktor Biaya | Impact on Price |
|---|---|
| Komposisi paduan | Higher Cr, C, Catatan, Mo, W increases cost significantly |
| Ketebalan lapisan | 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 |
| Kontrol kualitas | Strict inspection increases production cost |
2. Relationship Between Overlay Thickness and Cost
| Ketebalan overlay | Typical Cost Level | Aplikasi |
|---|---|---|
| 3–4 mm | Lebih rendah | Light abrasion conditions |
| 5–6 mm | Sedang | General industrial wear |
| 7–8 mm | Lebih tinggi | Lingkungan abrasi yang parah |
| 10 mm+ | Highest | Kondisi keausan ekstrem |
Thicker overlay layers require more welding passes and more alloy consumption, directly increasing cost.
3. Relationship Between Chemical Composition and Price
| Alloy Type | Elemen Utama | Tingkat Biaya |
|---|---|---|
| Standard chromium carbide overlay | Fe + C + Kr (20–30%) | Ekonomis |
| High-chromium complex alloy | Kr + C + Mo + Catatan | Sedang |
| Tungsten carbide reinforced | toilet + Ni/Fe matrix | Tinggi |
| Nickel-based overlay | Di dalam + Kr + B + Dan | Tinggi hingga sangat tinggi |
Higher alloy content improves wear resistance, ketahanan terhadap korosi, and heat resistance, but also increases raw material and processing cost.
4. Thickness vs Composition: Which Matters More?
- Ketebalan: Determines service life and wear allowance
- Komposisi: Determines hardness and wear mechanism
- Both together: Define final performance and price level
Dalam kebanyakan kasus, alloy composition has a greater impact on performance, while thickness mainly affects service life duration.
5. Why Better Composition Costs More
- Higher alloy cost (Kr, Catatan, W, Di dalam)
- More complex welding control
- Lower production speed
- Tighter quality requirements

Kesimpulan
Ya, 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.
