Duplex Stainless Filler Metal
ER2209 wire for controlled duplex stainless welding procedures
ER2209 is a duplex stainless filler-metal classification commonly used for welding 22Cr duplex grades such as 2205 when required by the approved procedure. Duplex weld quality depends on heat input, interpass temperature, shielding and backing gas, joint geometry, dilution and cooling rate so that corrosion resistance and phase balance are controlled together.

SAKY METAL reviews ER2209 enquiries against the stated classification, welding process, diameter, package, base materials, WPS, service conditions, inspection scope and documentation. Availability is confirmed for each requested combination; no stock, mechanical-property or corrosion-performance claim is implied without an agreed specification.
Selection note: Provide the base-metal UNS or EN grade, product thickness, process, joint design, heat-input window, interpass limit and corrosion-test requirements. Duplex welding parameters must be controlled by the WPS.
Grade Designations and Cross-References
| Product designation | ER2209 bare welding electrode / rod |
|---|---|
| AWS order reference | AWS A5.9/A5.9M ER2209; confirm the required standard revision |
| GB/T cross-reference | H00Cr22Ni9Mo3N |
| JIS cross-reference | YS2209 |
| DIN / European reference | 1.4462 |
| Important | Cross-references support material review but are not blanket substitution approvals. The purchase order, applicable standard revision and qualified WPS govern acceptance. |
Supply Forms and Ordering Parameters
| GMAW / MIG | Bare solid wire on spool or basket by enquiry; specify diameter, package style and net weight. |
|---|---|
| GTAW / TIG | Straight cut-length filler rods by enquiry; specify diameter, rod length, package and identification. |
| Other processes | Submerged-arc or other bare-wire requirements are reviewed against the process, wire/flux combination and governing procedure. |
| Dimensions | Diameter and tolerance must be stated on the RFQ; availability is confirmed for the requested process and package. |
| Identification | Grade, classification, batch or heat reference, size and package identification as required by the purchase order. |
| Documentation | Certificate of conformance, chemistry or classification records and EN 10204 documents when agreed. |
Typical Application Areas
- Duplex 2205 piping and equipment
- Offshore and oil-and-gas fabrication
- Chemical and petrochemical process systems
- Desalination and chloride-service equipment
These application areas are selection prompts rather than design approvals. Confirm filler compatibility through engineering review, the governing construction code and a qualified welding procedure.
Quality, Traceability and Welding Control
Before productionVerify grade, batch and WPS
Match package identification and certificates to the released procedure before wire enters production.
During weldingControl procedure variables
Use the qualified process, shielding system, heat-input range, interpass limit and contamination controls.
After weldingInspect to the project plan
Apply the specified visual, NDT, mechanical, chemistry or corrosion tests and retain traceability records.

ER2209 Welding Wire FAQs
What base materials are commonly associated with ER2209?
It is commonly used with 22Cr duplex grades such as 2205, subject to the governing specification, service and qualified procedure.
Why must heat input be controlled for duplex welding?
Heat input and cooling affect the weld microstructure, phase balance, toughness and corrosion behavior. The approved WPS defines the allowable range.
Which inspection details should be stated?
Include visual and NDT scope, chemistry or ferrite requirements if applicable, corrosion testing, impact testing and certificate requirements.
What information controls final product acceptance?
The purchase order, cited classification and revision, approved WPS, agreed test plan, package identification and issued material documentation control acceptance.
