TP310S (UNS S31008) Seamless Stainless Steel Tube Manufacturer & Supplier | Tengqi China
Tengqi is a premier manufacturer and global exporter of TP310S (UNS S31008) seamless stainless steel tubes, headquartered in Fujian, China. As a low-carbon version of the 310 alloy, TP310S is specifically engineered to provide superior oxidation resistance and structural integrity in continuous service temperatures up to 1035°C (1900°F).
Our SS 310S seamless tubing is manufactured using advanced cold-drawing and cold-rolling processes to meet the most stringent international standards, including ASTM A213, ASTM A269, and EN 10216-5. By controlling the carbon content, we ensure our tubes offer enhanced weldability and resistance to intergranular corrosion, making them the ideal choice for high-heat industrial infrastructure.
Technical Specifications: TP310S (UNS S31008 / 1.4845)
TP310S features a high Chromium (25%) and Nickel (20%) composition, providing a stable austenitic structure and excellent resistance to thermal fatigue.

Technical Parameter Specification & Range
Outer Diameter (OD) 6.0mm to 508mm
Wall Thickness (WT) 0.5mm to 40mm (SCH 10S - SCH XXS)
Standard Compliance ASTM A213 (Exchanger), ASTM A312 (Pipe), DIN 17458
Surface Finish Solution Annealed & Pickled (AP), Bright Annealed (BA), Polished
Testing 100% Hydrostatic, Eddy Current, PMI, and Grain Size Testing

Key Performance Benefits of Tengqi TP310S Tubes
• Superior Oxidation Resistance: The high chromium content allows for the formation of a protective, adherent oxide scale in oxidizing environments.
• Low Carbon Advantage: Specifically designed to minimize carbide precipitation during welding or high-temperature exposure, preventing sensitization.
• Resistance to Sulfidation: Excellent performance in moderately carburizing and sulfidizing atmospheres compared to lower-alloyed stainless steels.
• High-Precision Manufacturing: Our Fujian facility ensures tight dimensional tolerances and superior internal surface

Seamless Stainless Steel TP310S tube (TP310S / UNS S31008 / W.Nr. 1.4845) is the low-carbon 25/20 grade, resisting oxidation and carburization up to 1100 °C. Manufactured by Tengqi in Fujian, China, every heat is fully traceable, hydro-tested and available with third-party inspection (SGS / BV / TUV) on request.
