EN 10216-5 1.4462 Duplex Stainless Steel Seamless Pipe

Oct 10, 2025

The EN 10216-5 1.4462 seamless pipe, based on the European standard, has become the preferred material for energy, chemical, and marine engineering applications across Europe.
GNEE supplies 1.4462 Duplex Stainless Steel Seamless Pipes (also known as Duplex 2205), which are high-performance materials featuring a dual-phase microstructure of austenite and ferrite. Their manufacturing and testing strictly comply with the EN/ISO system, ensuring reliability under high pressure, corrosive environments, and extreme temperatures. These pipes are benchmark products that align with the EU's industrial sustainability goals.
Additionally, the UNS S32205 Stainless Steel Seamless Pipe offers excellent resistance to chloride stress corrosion cracking (SCC) and pitting corrosion (PREN≥35), with a tensile strength of 750–850 MPa and yield strength exceeding 450 MPa-outperforming conventional austenitic stainless steels. It is suitable for harsh environments such as oil and gas transportation (resistant to H₂S/CO₂ corrosion), high-pressure seawater desalination pipelines, and chemical reactors.

We offer EN 10216-5 seamless stainless steel tubes in various sizes, including grades 1.4307, 1.4401, 1.4404, 1.4571, 1.4541, and 1.4462. EN 10216-5 seamless tubes can be manufactured using hot or cold finishing processes, and can be heat treated for descaling and bright annealing. The internal and external surface finish of the tubes should conform to the typical requirements of the manufacturing process.
The diameter and wall thickness of the tubes should conform to the relevant tolerances specified in EN ISO 1127. Outside diameters are D1, D2, D4, and D4, and wall thicknesses are T1, T2, T3, and T4. EN 10216-5 seamless tubes can be manufactured to tighter tolerances upon request. Our facility can meet TC1 and TC2 testing requirements.Mail:es@gescosteel.com
