Seamless Stainless Steel TP316 |UNS S31600|1.4401 Tube

Seamless Stainless Steel TP316 Tubes (UNS S31600 / W.Nr. 1.4401) are premium-grade austenitic solutions engineered for exceptional mechanical strength and superior corrosion resistance in chloride-rich environments. As a premier manufacturer based in Fujian, China, Tengqi produces high-integrity seamless tubing that strictly adheres to ASTM A312, ASTM A213, and ASME SA213 international standards.

Distinguished by its strategic Molybdenum content (2-3%), our TP316 tubing provides significantly enhanced resistance to pitting and crevice corrosion compared to standard 304 grades. These tubes are indispensable for mission-critical applications in marine hardware, chemical reactors, and pharmaceutical processing equipment. Through advanced cold-drawing and precise solution annealing, Tengqi ensures every tube maintains a uniform microstructure and excellent surface finish, delivering reliable performance for the most demanding global industrial needs.

"For applications involving extensive welding, we also provide TP316L (UNS S31603) with lower carbon content to prevent sensitization and maintain intergranular corrosion resistance."
