3Giá thép tấm không gỉ mm
The price of a 3tấm thép không gỉ mm is calculated using a simple but effective formula: weight multiplied by unit price plus processing cost. By understanding thickness, density, and grade factors, buyers can estimate cost more accurately and compare different stainless steel materials effectively. This pricing method ensures transparency and consistency across different stainless steel specifications.
- Sự miêu tả
The price of a 3tấm thép không gỉ mm is not a fixed value. It is calculated based on material density, sheet dimensions, stainless steel grade, and processing costs. Understanding the pricing formula helps buyers estimate cost more accurately before purchasing.
Basic Price Calculation Formula
The standard pricing method for stainless steel sheets is based on weight (kg) × unit price (mỗi kg).
1. The Core Formula
Price = Weight (kg) × Unit Price (USD/kg) + Processing Cost
Ở đâu:
- Weight depends on thickness, chiều rộng, and length
- Unit price depends on stainless steel grade (304, 316, vân vân.)
- Processing cost includes cutting, hoàn thiện, and handling
2. Weight Calculation Formula
For stainless steel sheets, weight is calculated as:
Cân nặng (kg) = Độ dày (mm) × Chiều rộng (tôi) × Chiều dài (tôi) × 7.93
Ở đâu:
- 7.93 = density of stainless steel (g/cm³ converted factor)
Example for 3mm Stainless Steel Sheet (1m×2m)
Weight = 3 × 1 × 2 × 7.93 = 47.58 kg
3. Full Price Calculation Example
If:
- Thickness = 3mm
- Size = 1m × 2m
- Weight = 47.58 kg
- Unit price = 2.5 USD/kg
- Processing cost = 5 USD/sheet
Then:
Price = 47.58 × 2.5 + 5 = 124.95 USD
4. Key Factors Affecting Price
1. Lớp thép không gỉ
| Cấp | Mức chi phí |
|---|---|
| 201 | Thấp |
| 304 | Trung bình |
| 316 | Cao |
| 321 | Cao hơn |
| song công 2205 | Cao nhất |
Higher alloy content = higher price.
2. Hoàn thiện bề mặt
- 2Kết thúc B: standard cost
- BA kết thúc: chi phí cao hơn
- Số 4 / chải: additional processing cost
- Hoàn thiện gương: highest surface cost
3. Kích thước tờ
- Standard sizes (1000×2000mm, 1219×2438mm) are cheaper
- Custom sizes increase cutting cost
4. Market Metal Price
- Nickel and chromium price fluctuations directly affect stainless steel cost
- Global supply chain changes also impact pricing
5. Why 3mm Stainless Steel Sheet Has Stable Pricing Structure
So với tấm mỏng, 3tấm thép không gỉ mm:
- Have higher material weight per unit area
- Are usually produced through hot rolling or heavy cold rolling
- Require stronger cutting and processing equipment
This makes weight-based pricing more accurate and widely used in the industry.
