Seamless Stainless Steel TP309 |UNS S30900|1.4828 Pipe

Seamless Stainless Steel TP309 Pipes (UNS S30900 / W.Nr. 1.4828) are premium high-alloy austenitic solutions engineered for superior oxidation resistance and mechanical strength in elevated temperature environments. As a premier manufacturer based in China, We produces high-integrity seamless piping that strictly adheres to ASTM A312 and ASME SA312 international standards.

Distinguished by its high Chromium (23%) and Nickel (13%) content, our TP309 tubing provides exceptional resistance to scaling and carburizing atmospheres at continuous service temperatures up to 980°C (1800°F). These pipes are indispensable for mission-critical applications in boiler baffles, furnace components, and high-temperature chemical processing units. Through advanced cold-drawing and precise solution annealing, We ensures every pipe maintains a uniform microstructure and optimized creep strength, offering superior durability under intense thermal stress.

“For applications requiring lower carbon content to improve weldability and prevent carbide precipitation, we also offer TP309S (UNS S30908).”
