SUPER DUPLEX STAINLESS STEEL · TECHNICAL SOURCING
Super Duplex 2507 Stainless Steel
Specification-led sourcing of Super Duplex 2507 products for demanding corrosion and strength requirements.
MNK-G.S.A coordinates plate, bar, tube, pipe, fittings, flanges, forgings and drawing-based components by exact designation, product standard, dimensions, condition and inspection plan.
Material and Classification Identity
- Manufacturer technical literature identifies the 2507 family as UNS S32750 and EN 1.4410.
- EN material name published for this family: X2CrNiMoN 25-7-4.
- Super Duplex 2507 is not automatically interchangeable with Duplex 2205 or another super-duplex grade. The governing specification and service assessment control selection.
Standards and Supply Definition
| Plate, sheet and strip | ASTM A240 or EN 10088-2, where applicable |
| Seamless and welded tube | ASTM A789; seamless tube may also be ordered under EN 10216-5 |
| Seamless and welded pipe | ASTM A790 |
| Bar | ASTM A479 or EN 10088-3 |
| Flanges and fittings | ASTM A182 and ASTM A815 within their respective scopes |
Application Context
Manufacturer literature lists applications such as seawater cooling, desalination, geothermal service, refineries and petrochemical equipment. These are application examples, not automatic material-selection approval. Chlorides, temperature, pressure, fabrication, design code and corrosion assessment must be reviewed for the project.
RFQ and Quality Controls
- Exact UNS / EN designation and product standard
- Solution-annealed condition, dimensions and tolerances
- EN 10204 documentation, PMI, corrosion testing, NDT and traceability
- WPS, filler classification, heat input, interpass and phase-balance controls
- Project, class, code or OEM approval requirements

Technical Sources
Alleima SAF 2507 technical datasheet — Product standards and application information are manufacturer-specific evidence. MNK verifies the quoted manufacturing source and customer specification for each inquiry.
Relevant ISO References
Use the current authorised edition together with the governing product specification, project requirements and inspection documents. A standards reference does not establish automatic grade equivalence or product approval.
Project-Specified Corrosion and Phase Tests
Critical-temperature, ferric-chloride or detrimental-phase requirements must be tied to the governing product standard and purchase order.
