Seamless Stainless Steel TP310 |UNS S31000|1.4841 Pipe
Featuring a strategic enrichment of 25% Chromium and 20% Nickel, our TP310 tubing develops a tenacious protective scale that ensures superior performance at continuous service temperatures up to 1100°C (2012°F). These pipes are indispensable for mission-critical applications in radiant tubes, muffle furnaces, and high-temperature chemical processing units. Through advanced cold-drawing and precise solution annealing, Tengqi guarantees a uniform microstructure and optimized creep strength, providing a reliable choice for the most demanding thermal cycling conditions.
“For applications requiring lower carbon content for welding, we also offer TP310S (UNS S31008), and for higher creep strength, TP310H (UNS S31009) is available.”
Seamless Stainless Steel TP310 Pipe (TP310 / UNS S31000 / W.Nr. 1.4841) is a 25/20 austenitic grade for continuous high-temperature service in oxidizing atmospheres. Manufactured by Tengqi in Fujian, China, every heat is fully traceable, hydro-tested and available with third-party inspection (SGS / BV / TUV) on request.
