310 / 310S Stainless Steel Coil And Strip

what is 310 / 310S Stainless Steel Coil and Strip?

Both 310 and 310S stainless steel coils and strips are austenitic stainless steels, possessing excellent high-temperature resistance and oxidation resistance, making them ideal for applications such as furnace components, heat exchangers, and chemical equipment. The main difference lies in the lower carbon content of 310S compared to 310, which gives it better weldability and reduces the risk of sensitization and embrittlement during high-temperature service.

 

If you are looking for a heat-resistant and corrosion-resistant stainless steel material, 310 and 310S stainless steel coil and strip are excellent choices. Both belong to the austenitic stainless steel family and are specifically designed for high-temperature applications where oxidation and scaling resistance are critical.

What are the differences between 310 and 310S stainless steel?

The main difference between 310 and 310S stainless steel lies in their carbon content: 310 has a maximum carbon content of 0.25%, while 310S has a maximum carbon content of 0.08%. This difference makes 310S more resistant to weld-related carbide precipitation and sensitization, thus improving its weldability and corrosion resistance in certain high-temperature applications; while the higher carbon content of 310 gives it higher high-temperature strength. All other chemical components, such as chromium and nickel, are the same in both grades.

 

310 Stainless Steel Coil Price Per kg

The price of 310 stainless steel coil typically fluctuates depending on thickness, width, surface treatment, and market conditions. For reference, a 0.5mm × 1000mm × coil of 310 stainless steel sheet costs approximately USD 8.5–9.5 per kg, while thicker (e.g., 2mm) or wider coils may cost USD 9.8–11 per kg. Prices will vary depending on availability, certification requirements (e.g., ASTM, EN), surface treatment (2B, BA), and shipping destination. It is recommended to contact a reliable supplier with specific thickness, width, length, surface treatment, and quantity for an accurate quote.
