EN 10216-5 1.4410 Stainless Steel Tube Supplier

GNEE supplies 1.4410 duplex stainless steel seamless pipes (UNS S32750) compliant with the EN 10216-5 standard. This super duplex stainless steel material features an austenitic-ferritic duplex microstructure, delivering high strength and exceptional corrosion resistance, particularly against chloride stress corrosion cracking (SCC) and pitting. The 1.4410 pipes are typically solution annealed at 1050°C–1100°C (water quenched) to stabilize the microstructure, with surface options including bright annealed finishes (2B or mirror effects) and high dimensional precision (e.g., outer diameter tolerance ±0.10mm, wall thickness tolerance ±10%), while supporting customized processing.

Applications of 1.4410 stainless steel pipes include oil and gas pipelines, seawater desalination equipment, chemical reactors, and marine engineering components. They are suitable for harsh environments ranging from -50°C to 300°C.

UNS S32750 vs. duplex stainless steel 2205 (S31803)

UNS S32750 has higher chromium, molybdenum, and nitrogen contents than duplex stainless steel 2205 (chromium content is 25% and 22%, respectively; molybdenum content is 4% and 3%, respectively). This compositional difference results in a higher PREN value for UNS S32750 (typically >40, while the PREN value for duplex stainless steel 2205 is typically 34-36).

Stainless Steel 1.4410 Tube Factory

Our factory strictly adheres to ASTM A923 Method B or Method C testing. We verify the absence of brittle σ phase in the pipe through Charpy V-notch impact testing at -40°C. We ensure that its impact energy value far exceeds standard requirements, guaranteeing that SS 2507 seamless pipe will never experience brittle fracture under low temperatures or extreme loads.
