Stages Involved in Producing SS 310S Seamless Pipe
As a leading 310S stainless steel pipe manufacturer, we make our 310S stainless steel pipe through a precise hot extrusion or cold drawing process. We start with high-quality solid billet, pierce it to make a hollow shell and then size and straighten the pipe. To make sure that every UNS S31008 pipe has a smooth finish and has maximum corrosion resistance, it goes through solution annealing and pickling.

What are the Features of Alloy 310S Pipe?
AISI 310S stainless steel pipes have 4 distinct characteristics. These are high temperature, fabrication, weldability and corrosion resistance.
- High-Temperature Performance: The 310S seamless stainless steel pipe is designed for continuous service at temperatures up to 1150°C. Its high chromium and nickel content provides excellent resistance to oxidation and scaling in high-heat environments. It also resists thermal fatigue and cyclic heating.
- Fabrication: The AISI 310S stainless steel pipe is readily fabricated by standard commercial procedures. While tougher than carbon steel, it can be formed and machined effectively if tools are sharp and power is sufficient.
- Weldability: The pipe is generally weldable by most standard fusion and resistance techniques. The low carbon content (compared to 310) reduces carbide precipitation during welding. This ensures the joints remain strong and resistant to corrosion.
- Corrosion Resistance: The Grade Stainless Steel 310S Pipe provides excellent resistance to aqueous corrosion because of its high chromium level. It specifically excels in environments where mild cyclic oxidation or carburisation might otherwise damage lower-grade alloys.
What is the Equivalent Standard for 310S Stainless Steel?
310S pipe is commonly known as UNS S31008, which is its standard equivalent designation. Some of its global equivalents are AISI 310S, EN 1.4845, and JIS SUS 310.

Frequently Asked Questions
-
What is a Stainless Steel 310S pipe?Stainless Steel 310S pipe, commonly known as 2520 stainless steel pipe in China is an austenitic stainless steel grade. It has a low carbon content (≤0.08%) and can resist oxidation at high temperatures up to 1150°C. It is one of the grades of stainless steel seamless pipe.
-
Difference between SS 310S and 310 pipe?The main difference between SS 310S and 310 pipes is their carbon content. 310S has less carbon (0.08%) than 310 (max 0.25%). This makes it less likely for carbide precipitation and improves weldability and intergranular corrosion resistance.
