• Inflow^™ Plus 355 is our high strength, multi-certified, hot-finished HFI welded pressure tube.

• Primary standard EN 10217-3 Grade P355NH.
• Multi-certified satisfying the mechanical properties of grades in other industry referenced standards, e.g. DIN1626 St52.0N/G, DIN1628 St52.4 and DIN17178 WSt E 355.
• Suitable substitute for equivalent hot-finished fine grain seamless tube grades e.g. DIN1629 St52.0N, DIN1630 St52.4, & DIN17179 WSt E355.
• General engineering tube to EN 10219 Grade S355J2H (for sizes greater than, equal to OD219.1mm).
• Fully weldable.
• Fully killed steel produced to fine grain practice for enhanced ductility.
• Quality designation TC1 supplied as standard.
• Quality designation TC2 option for sizes ≥ OD219.1mm.
• Inflow™ Plus 355 provides full PED compliance being suitable for equipment in PED categories I, II, III or IV, also aligned with AD2000 Merkblatt W4.
• Suitable for pressure applications and temperature range -20 to +400ºC (except EN 10219).
• OD and ID weld beads fully removed.
• Due to the superior mechanical properties of Inflow™ Plus 355, the same pressure integrity as for Inflow™ Plus 235 can be obtained with thinner walls.
• The associated weight savings will enable a reduction in supporting load bearing structures, hangers and brackets etc.
• Increased wear resistance – providing improved service life for applications where this is a consideration.
• Backed up by technical experts who can offer advice on applications and product suitability.
• Inflow™ Plus 355 is fully technically supported with a range of available product brochures.
• Certified to BES 6001 Responsible Sourcing standard.
• Supplied with 3.1 inspection certification to EN 10204.

Note 1: It may be possible to demonstrate lower temperature properties if full application is known, please contact one of our account managers to discuss your requirements.
