We offer EN 10216-5 Seamless Stainless Steel Tube in a wide range of sizes, steel numbers include 1.4307, 1.4401, 1.4404, 1.4571, 1.4541 and 1.4462. EN 10216-5 seamless tubes can be manufactured in hot-finished and cold-finished, with heat-treated descaled and bright annealed conditions. The internal and external surface finish of the tubes shall be typical of the manufacturing process.
EN 10216-5 Seamless Tubes shall be designed by outside diameter and wall thickness, The diameter and the wall thickness of the tubes shall be within the relevant tolerance limits given in EN ISO 1127, D1, D2, D4, and D4 for outside diameters and T1, T2, T3 and T4 for wall thicknesses, tight tolerances for EN 10216-5 seamless tubes are available upon request. TC1 and TC2 test requirements can met at our mill.
