سعر ورقة Ss للكيلوغرام الواحد
The pricing of stainless steel sheets is inherently weight-based because both raw materials and manufacturing processes are measured in mass. ال price per kg provides a standardized and transparent way to evaluate cost across different sizes, الدرجات, and specifications.
- وصف
The price of stainless steel sheet is commonly quoted in السعر للكيلوغرام الواحد (كجم) 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:
- حديد (الحديد)
- الكروم (كر)
- النيكل (في)
- الموليبدينوم (شهر)
These elements are traded globally by weight. لذلك:
- Higher الوزن = more raw material consumption
- More alloy content = higher cost per kg
على سبيل المثال:
- 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, هُم thickness determines weight, and therefore total price.
وزن (كجم)= الطول (م)× العرض (م)× السُمك (مم)×7.93\text{وزن (كجم)} = نص{طول (م)} \مرات نص{عرض (م)} \مرات نص{سماكة (مم)} \مرات 7.93
Where:
- 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:
- المتداول البارد
- الصلب
- التشطيب السطحي (2ب, بكالوريوس, مرآة)
- Cutting and leveling
are often calculated based on processing weight (tons or kg).
Heavier materials require:
- More energy
- Longer processing time
- 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, إلخ.)
- Influenced by alloy element market prices
2. Manufacturing Cost
- Rolling process (المدرفلة على الساخن أو المدرفلة على البارد)
- Annealing method (bright annealing, الصلب الحل)
3. Surface Finish Cost
- 2ب (standard industrial finish)
- بكالوريوس (صلب مشرق)
- 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 |
|---|---|---|
| المواد الخام | تكوين سبائك (per kg) | Core cost driver |
| Rolling Process | Weight processed | Affects production cost |
| الصلب | Heat treatment per ton | Impacts structure and quality |
| الانتهاء من السطح | Processing complexity | Adds value |
| التعبئة والتغليف & المناولة | Weight and protection needs | Minor but necessary |
Total Price Formula (Simplified)
السعر الإجمالي = الوزن (كجم)×Price per kg\text{السعر الإجمالي} = نص{وزن (كجم)} \مرات نص{السعر للكيلو الواحد}
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 كجم)
Key Factors That Affect Price Per Kg
- Stainless steel grade (alloy content)
- Sheet thickness and dimensions
- Surface finish requirements
- Production process complexity
- Order quantity (economies of scale)
