3Preço da chapa de aço inoxidável mm
The price of a 3chapa de aço inoxidável 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.
- Descrição
The price of a 3chapa de aço inoxidável mm is not a fixed value. It is calculated based on material density, dimensões da folha, 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 (por kg).
1. The Core Formula
Price = Weight (kg) × Unit Price (USD/kg) + Custo de processamento
Onde:
- Weight depends on thickness, largura, and length
- Unit price depends on stainless steel grade (304, 316, etc.)
- Processing cost includes cutting, acabamento, and handling
2. Weight Calculation Formula
Para chapas de aço inoxidável, weight is calculated as:
Peso (kg) = Espessura (milímetros) × Largura (eu) × Comprimento (eu) × 7.93
Onde:
- 7.93 = densidade do aço inoxidável (g/cm³ converted factor)
Example for 3mm Stainless Steel Sheet (1m × 2m)
Peso = 3 × 1 × 2 × 7.93 = 47.58 kg
3. Full Price Calculation Example
If:
- Thickness = 3mm
- Size = 1m × 2m
- Peso = 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. Classe de aço inoxidável
| Nota | Nível de custo |
|---|---|
| 201 | Baixo |
| 304 | Médio |
| 316 | Alto |
| 321 | Mais alto |
| Dúplex 2205 | Mais alto |
Higher alloy content = higher price.
2. Acabamento de superfície
- 2Acabamento B: standard cost
- Acabamento BA: custo mais alto
- Nº 4 / escovado: additional processing cost
- Acabamento espelhado: highest surface cost
3. Tamanho da folha
- 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
Comparado com folhas finas, 3mm chapas de aço inoxidável:
- 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.
