SSシートの1kgあたりの価格
The pricing of stainless steel sheets is inherently weight-based because both raw materials and manufacturing processes are measured in mass. の price per kg provides a standardized and transparent way to evaluate cost across different sizes, 成績, and specifications.
- 説明
The price of stainless steel sheet is commonly quoted in キログラムあたりの価格 (kg) because stainless steel is fundamentally a mass-based commodity material. Regardless of shape or size, the cost is directly tied to how much raw material is used, making weight the most accurate and standardized pricing basis in global trade.
Why Stainless Steel Sheet Price is Based on Weight
1. Raw Material Cost is Weight-Driven
Stainless steel is produced from alloying elements such as:
- 鉄 (鉄)
- クロム (Cr)
- ニッケル (で)
- モリブデン (モー)
These elements are traded globally by weight. したがって:
- Higher الوزن = more raw material consumption
- More alloy content = higher cost per kg
例えば:
- 304 stainless steel contains nickel → higher price
- 316 stainless steel contains molybdenum → even higher price
2. Thickness Directly Affects Total Weight
Even if two sheets have the same length and width, 彼らの thickness determines weight, and therefore total price.
重さ (kg)=長さ (メートル)×幅 (メートル)×厚み (mm)×7.93\text{重さ (kg)} = テキスト{長さ (メートル)} \text 倍{幅 (メートル)} \text 倍{厚さ (mm)} \回 7.93
どこ:
- 7.93 is the density of stainless steel (g/cm³ equivalent factor)
This explains why:
- Thicker sheets cost more
- Larger dimensions increase total price proportionally
3. Processing Cost is Also Weight-Related
Manufacturing costs such as:
- 冷間圧延
- アニーリング
- 表面仕上げ (2B, BA, 鏡)
- Cutting and leveling
are often calculated based on processing weight (tons or kg).
Heavier materials require:
- More energy
- 処理時間が長くなる
- Higher equipment load
How SS Sheet Price Per Kg is Calculated
The final quotation per kg is typically composed of several cost components:
1. Base Material Cost
- Depends on stainless steel grade (201, 304, 316, 等)
- Influenced by alloy element market prices
2. Manufacturing Cost
- Rolling process (hot rolled or cold rolled)
- Annealing method (bright annealing, solution annealing)
3. Surface Finish Cost
- 2B (standard industrial finish)
- BA (光輝焼鈍)
- Polished or mirror finish
4. Thickness Tolerance and Precision
- Tighter tolerances increase production difficulty
- Ultra-thin or precision sheets have higher cost per kg
Example Price Calculation Structure
| Cost Component | Calculation Basis | Influence on Final Price |
|---|---|---|
| 原材料 | 合金組成 (1kgあたり) | Core cost driver |
| Rolling Process | Weight processed | Affects production cost |
| アニーリング | Heat treatment per ton | Impacts structure and quality |
| 表面仕上げ | Processing complexity | Adds value |
| 包装 & 取り扱い | Weight and protection needs | Minor but necessary |
Total Price Formula (Simplified)
合計価格=重量 (kg)×1kgあたりの価格本文{合計価格} = テキスト{重さ (kg)} \text 倍{1kgあたりの価格}
This is why in international trade:
- Buyers often calculate total cost based on final shipment weight
- Suppliers quote FOB or CIF price per ton (1000 kg)
Key Factors That Affect Price Per Kg
- ステンレス鋼種 (合金含有量)
- Sheet thickness and dimensions
- Surface finish requirements
- Production process complexity
- Order quantity (economies of scale)
