DUPLEX STAINLESS STEEL · SPECIFICATION-LED SOURCING
Duplex 2205 Stainless Steel
Technical sourcing of Duplex 2205 products by exact UNS or EN designation, product standard, dimensions, condition and inspection requirements.
MNK-G.S.A coordinates plate, sheet, bar, tube, pipe, fittings, flanges, forgings and components manufactured to drawing across qualified European, Asian and global supply routes.
Material and Classification Identity
- Manufacturer technical literature identifies the 2205 family as UNS S31803 / S32205 and EN 1.4462.
- EN material name published for this family: X2CrNiMoN 22-5-3.
- The requested UNS designation, EN designation and governing product standard must be stated separately; a family name alone is not a complete purchase specification.
Standards and Supply Definition
| Plate, sheet and strip | ASTM A240 or EN 10088-2, where applicable to the requested product |
| Seamless and welded tube | ASTM A789; seamless tube may also be ordered under EN 10216-5 |
| Seamless and welded pipe | ASTM A790 |
| Bar and shapes | ASTM A276 / A479 or EN 10088-3 |
| Flanges, valves and fittings | ASTM A182 and ASTM A815 within their respective scopes |
Application Context
Duplex 2205 is considered for specification-driven duties requiring a combination of strength and corrosion resistance. Manufacturer literature discusses resistance to chloride-related stress corrosion cracking, pitting and crevice corrosion, but suitability still depends on medium, temperature, pressure, fabrication route and design code.
RFQ and Quality Controls
- Exact grade and product-form standard
- Dimensions, tolerances, condition and heat treatment
- EN 10204 document type, PMI, corrosion tests, NDT and traceability
- WPS, filler classification, heat input and project approval for welded fabrication
- Quantity, packing, delivery destination and required delivery date
