Seamless Stainless Steel TP304 |UNS S30400|1.4301 Pipe
Our TP304 seamless pipes offer exceptional corrosion resistance and mechanical strength, making them indispensable for chemical processing, oil & gas, and high-pressure construction projects. Known for its superior formability and weldability, our 304 stainless steel tubing is also a reliable choice for the food and beverage industry, ensuring long-lasting performance and hygienic integrity. Through advanced cold-drawing and vacuum annealing, guarantees tight dimensional tolerances and a superior surface finish for every order.
Seamless Stainless Steel TP304 Pipe (TP304 / UNS S30400 / W.Nr. 1.4301) is a general-purpose austenitic grade with excellent formability and resistance to oxidizing media. Manufactured by Tengqi in Fujian, China, every heat is fully traceable, hydro-tested and available with third-party inspection (SGS / BV / TUV) on request.
