A312 / SA312 TP310S (UNS S31008) Stainless Steel Seamless Pipe, Superheater And Reheater Tubing
Overview of A312 TP310S Stainless Steel Seamless Pipe
A312 TP310S Stainless Steel Seamless Pipe is a high-temperature, corrosion-resistant pipe made from low-carbon 310S austenitic stainless steel. Manufactured under the ASTM A312 standard, it is ideal for use in extreme environments such as furnaces, heat exchangers, and petrochemical plants. The alloy's high chromium and nickel content provides excellent resistance to oxidation, sulfidation, and carburization, while the low carbon content improves weldability and minimizes the risk of intergranular corrosion.
Why Use TP310S Instead of TP310?
- TP310S has lower carbon content, reducing the risk of sensitization and intergranular corrosion after welding or prolonged exposure to high temperatures.
- Better for welded structures and components that operate in cyclic high-temperature environments.
