Application and selection limits
ESAB identifies Exaton 2594 for SAF 2507 and other super-duplex steels. This does not automatically approve every S32750, S32760 or other super-duplex fabrication. Phase balance, heat input, interpass temperature, gas protection, corrosion requirements and the governing specification must be assessed for the project.
RFQ and Quality Controls
- Exact base-material grade and product standard, thickness and joint configuration
- Required AWS and/or EN ISO classification; wire or rod, diameter and package
- Approved WPS/PQR, welding process, shielding and backing gas, heat input and interpass requirements
- Required classification-society, OEM or independent approvals and manufacturing location
- Batch certificate, chemical analysis, traceability, quantity and delivery destination

Packaging entries are catalogue examples, not stock commitments or a complete size range. Approvals depend on the product and manufacturing location. The references do not imply a supply partnership or approval for a project; the customer specification and approved welding procedure govern selection.
Relevant ISO Reference
Use the current authorised ISO publication together with the governing specification, manufacturer documentation and project requirements. A reference link alone does not establish grade equivalence, product compliance or application approval.
