Application and selection limits
ESAB identifies Exaton 2209 for duplex steels including SAF 2205 and SAF 2304. Suitability depends on the exact base material, approved WPS, heat input, interpass temperature, shielding and backing gas, joint geometry, service conditions and required project or classification-society approvals.
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.
