Цена листа Ss за кг

The price of stainless steel sheet is commonly quoted in цена за килограмм (кг) 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:

• Железо (Фе)
• Хром (Кр)
• Никель (В)
• Молибден (Мо)

These elements are traded globally by weight. Поэтому:

• Higher الوزن = more raw material consumption
• More alloy content = higher cost per kg

Например:

• 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, их thickness determines weight, and therefore total price.

$\text{Масса (кг)}=\text{Длина (м)}\times \text{Ширина (м)}\times \text{Толщина (мм)}\times 7.93$

Где:

• 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:

• Холодная прокатка
• Отжиг
• Отделка поверхности (2Б, бакалавр, зеркало)
• Cutting and leveling

are often calculated based on processing weight (tons or kg).

Heavier materials require:

• More energy
• Более длительное время обработки
• 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, и т. д.)
• 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

• 2Б (standard industrial finish)
• бакалавр (яркий отожженный)
• Полированная или зеркальная отделка

4. Thickness Tolerance and Precision

• Tighter tolerances increase production difficulty
• Ultra-thin or precision sheets have higher cost per kg

Example Price Calculation Structure

Total Price Formula (Simplified)

$\text{Общая стоимость}=\text{Масса (кг)}\times \text{Цена за кг}$

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 кг)

Key Factors That Affect Price Per Kg

• Марка нержавеющей стали (alloy content)
• Sheet thickness and dimensions
• Требования к отделке поверхности
• Production process complexity
• Order quantity (economies of scale)
