SUPER DUPLEX FILLER METAL · TECHNICAL SOURCING
ER2594 Super Duplex Welding Consumables
Specification-led sourcing of ER2594 solid wire and rods for controlled super-duplex welding applications.
MNK-G.S.A coordinates the exact filler classification, process, diameter, packaging, batch documentation, approvals and delivery against project requirements.
Classification Identity
- AWS A5.9/A5.9M:2022 is the AWS classification framework for bare stainless-steel welding electrodes, wires, strips and rods.
- A current manufacturer product page identifies AWS A5.9 ER2594 and EN ISO 14343-A W 25 9 4 N L.
- ISO 14343:2025 is the current international classification standard; ISO 14343:2017 is withdrawn.
- A shared commercial designation does not establish identical approvals, chemistry limits, diameter availability or application suitability across manufacturers.
Standards and Supply Definition
| AWS classification | AWS A5.9/A5.9M:2022 — ER2594 |
| International framework | ISO 14343:2025 |
| Manufacturer EN ISO classification | EN ISO 14343-A W 25 9 4 N L |
| Supply definition | GMAW/MIG wire or GTAW/TIG rod, as produced and certified for the quotation |
| Selection authority | Approved WPS/PQR, project specification, class/OEM requirements and base-material documentation |
Application Context
Manufacturer guidance places the referenced product in super-duplex welding, including SAF 2507 application context. It is not universal approval for every S32750, S32760 or other super-duplex fabrication. Phase balance, heat input, interpass control, shielding, corrosion requirements and governing code must be assessed for the project.
RFQ and Quality Controls
- Exact super-duplex base-material designation
- Approved WPS/PQR, welding process and heat-input controls
- Wire or rod diameter and package
- Required class, OEM or third-party approvals
- Batch certificate, traceability, quantity and delivery destination
