TP310 (UNS S31000) Seamless Stainless Steel Tube Manufacturer & Supplier | Tengqi China
Tengqi is a leading manufacturer and global supplier of TP310 (UNS S31000) seamless stainless steel tubes, based in the premier industrial zone of Fujian, China. Specifically engineered for high-temperature service, our TP310 tubing provides an elite combination of oxidation resistance, high-temperature strength, and structural stability in environments up to 1100°C (2010°F).
As a specialized 310 stainless steel seamless pipe manufacturer, we produce high-alloy austenitic tubing that meets rigorous international standards, including
Core Advantages of Tengqi TP310 Seamless Tubing
• Exceptional Oxidation Resistance: Maintains a protective surface scale in oxidizing atmospheres, preventing metal loss at extreme temperatures.
• Corrosion Resistance in Hot Media: Superior performance in mildly carburizing and nitriding environments compared to 304 or 316 grades.
• Structural Integrity: Our precision cold-drawing process ensures uniform wall thickness and concentricity, vital for high-pressure thermal applications.
• Advanced Metallurgy: Controlled chemistry minimizes the formation of the brittle sigma phase, extending the service life of furnace and boiler components.
