310S stainless steel is an austenitic chromium-nickel alloy with excellent resistance to oxidation and high-temperature corrosion. It is commonly used in furnace components, heat treatment trays, kiln linings, and petrochemical applications. The “S” in 310S stands for its low carbon content, which improves weldability and reduces the risk of carbide precipitation. Due to its high alloy content, 310S is priced higher than 304 or 316 stainless steel. This guide provides updated 2025 market prices for 310S stainless steel products by type and size, primarily based on data from Chinese suppliers.
310S Stainless Steel Price by Product Type (FOB China, 2025)
Prices vary based on form, size, processing method, and surface finish. Here’s a price summary by product type:
| Product Type | Size Range | Price (USD/kg) | MOQ |
|---|---|---|---|
| Plate / Sheet | 1 mm – 50 mm | $4.60 – $6.00 | 500 kg |
| Seamless Pipe | OD 6 mm – 323 mm | $5.50 – $6.80 | 300 kg |
| Welded Pipe | OD 10 mm – 609 mm | $4.20 – $5.50 | 500 meters |
| Round Bar | Ø 6 mm – 200 mm | $5.00 – $6.50 | 200 kg |
| Coil / Strip | 0.2 mm – 5 mm | $4.80 – $6.30 | 500 kg |
310S Price by Comparison to Other Stainless Steels
310S is more expensive than standard grades like 304 and 316 but cheaper than super austenitic alloys such as 904L.
| Grade | Approx. Price (USD/kg) | Typical Use |
|---|---|---|
| 304 | $2.50 – $3.20 | General-purpose, food equipment |
| 316L | $3.80 – $4.80 | Chemical tanks, marine hardware |
| 310S | $4.60 – $6.80 | High-temperature applications |
| 904L | $8.50 – $11.00 | Strong acid resistance |
310S Pipe and Sheet Price by Size
Prices per meter or sheet depend on thickness and diameter. Below are sample prices:
| Product | Size | Approx. Price (USD/unit) |
|---|---|---|
| Seamless Pipe | 2″ SCH 40 (6m length) | $110 – $145 |
| Welded Pipe | 4″ SCH 40 (6m length) | $160 – $200 |
| Sheet | 4′ x 8′ x 3 mm | $125 – $160 |
| Sheet | 4′ x 8′ x 6 mm | $230 – $280 |
Price Factors for 310S Stainless Steel
Several factors influence the cost of 310S stainless steel products:
| Factor | Effect on Price |
|---|---|
| Nickel Content (~20%) | High nickel prices directly raise alloy cost |
| Product Type | Seamless pipes and precision bars cost more than sheets |
| Finish | Polished or bright surfaces cost more |
| Order Volume | Larger quantities reduce per kg cost |
