S32750, also known as SAF 2507 or UNS S32750, is a super duplex stainless steel that offers excellent corrosion resistance and very high mechanical strength. It is commonly used in offshore platforms, pressure vessels, chemical processing, and desalination equipment. S32750 round bar is one of the most popular forms of this alloy, often used in shafts, flanges, fasteners, and machined components. The price of S32750 round bar can vary depending on diameter, condition (hot rolled, forged, polished), and global nickel price trends.
S32750 Round Bar Price per Kg (FOB China)
The following table outlines the typical price ranges based on bar diameter:
| Diameter (mm) | Condition | Price Range (USD/kg) | Remarks |
|---|---|---|---|
| 10 – 25 | Hot Rolled / Peeled | 11.50 – 13.00 | For fasteners, valves |
| 26 – 50 | Annealed / Machined | 12.00 – 13.80 | Used in flanges, shafts |
| 51 – 100 | Forged / Rough Machined | 13.50 – 15.00 | Heavy-duty applications |
| > 100 | Forged | 15.50 – 17.00 | Custom orders |
Factors Affecting the Price
1. Nickel Price Fluctuations: As a high-nickel alloy, S32750 is sensitive to LME nickel prices. Price spikes in nickel directly impact bar cost.
2. Bar Diameter and Weight: Larger diameters require more raw material and slower cooling, raising the unit price.
3. Production Method: Forged and machined bars cost more than hot-rolled ones due to labor and time.
4. Surface Finish and Tolerance: Peeled, polished, or ground surfaces may add $0.50–$1.00/kg depending on finish level.
5. Order Quantity: Small batch orders (<500 kg) usually cost 5–8% more than bulk orders due to setup costs.

Related Questions
What is the S32750 round bar price per kg?
The price is typically $11.50 to $17.00/kg FOB China, depending on size and surface finish.
Why is S32750 more expensive than 316L?
It contains more alloying elements like Cr, Mo, and N, offering higher corrosion resistance and strength, which raises the cost.
Is S32750 round bar available in small sizes?
Yes, sizes as small as 10 mm diameter are available, commonly used in precision fasteners and valve stems.
