High-Carbon Niobium-Stabilized Filler
ER347H wire for elevated-temperature stabilized stainless procedures
ER347H is identified here as a high-carbon, niobium-stabilized stainless welding-wire grade. It may be considered for elevated-temperature stabilized stainless fabrication when explicitly required, but creep, oxidation and long-term joint performance must be verified through the governing design code and qualified procedure.
ClassificationER347H
Primary useHigh-carbon stabilized stainless joints
Supply routeSpool wire & cut rods
Request ER347H stainless steel welding wire with the required standard, dimensions, tolerance, finish, inspection and mill test certificates from SAKY METAL.

Grade Designations and Cross-References
| Product designation | ER347H bare welding electrode / rod |
|---|---|
| AWS order reference | AWS A5.9/A5.9M ER347H; confirm the required standard revision |
| GB/T cross-reference | H06Cr20Ni10Nb |
| JIS cross-reference | YS347H |
| DIN / European reference | 1.4551 |
| 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

| 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
- Elevated-temperature stabilized stainless equipment
- Petrochemical and thermal-process fabrication
- Heat-resistant piping components
- Repair work governed by a qualified high-temperature WPS
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.

ER347H Welding Wire FAQs
What distinguishes ER347H from ER347L?
The suffixes identify different requested composition ranges. They should not be treated as interchangeable procurement descriptions.
Does ER347H alone establish creep performance?
No. Long-term performance depends on the welded joint, procedure, heat treatment, stress, temperature and applicable design code.
What should be included for high-temperature service?
Provide base metals, design temperature, pressure or stress, atmosphere, thermal cycles, WPS, inspection 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.
