18Cr-8Ni Austenitic Filler Metal
ER308 wire supplied to the classification, process and package your WPS requires
ER308 is an austenitic stainless welding-wire classification generally associated with nominal 18Cr-8Ni filler-metal chemistry. It is selected for compatible austenitic stainless fabrication only after the base-metal grade, carbon requirement, corrosion environment, heat input and procedure qualification have been reviewed.
ClassificationER308
Primary useGeneral austenitic stainless fabrication
Supply routeSpool wire & cut rods
Request ER308 stainless steel welding wire with the required standard, dimensions, tolerance, finish, inspection and mill test certificates from SAKY METAL.

Standards, supply and inspection
ER308 Stainless Steel Welding Wire | YS308 | DIN 1.4316 ER308 is an austenitic stainless welding-wire classification generally associated with nominal 18Cr-8Ni filler-metal chemistry. It is selected for compatible austenitic stainless fabrication only after the base-metal grade, carbon requirement, corrosion environment, heat input and procedure qualification have been reviewed.
| Material / grade | ER308; GB/T H0Cr21Ni10; JIS YS308; DIN 1.4316 |
|---|---|
| Product form | Bare solid welding wire on spool and straight cut-length filler rods by enquiry; other bare-wire packages subject to review. |
| Standards and order reference | AWS A5.9/A5.9M classification; state required revision plus project, code and WPS references. |
| Dimensions and tolerances | Specify welding process, wire or rod diameter, cut length where applicable, spool or package type and tolerance. |
| Surface and supply condition | Clean bare filler metal, securely packaged to limit handling damage and contamination; storage requirements by purchase order. |
| Inspection options | Visual and dimensional inspection, classification or chemistry review, traceability and purchaser-specific testing by agreement. |
| MTC and traceability | Certificate of conformance and heat or batch traceability; EN 10204 documentation or additional records when agreed. |
| Typical applications | Austenitic stainless fabrication; Process equipment and general assemblies; Sheet, tube and pipe joining under a qualified WPS; Shop and field welding by specified process |
| RFQ checklist | Grade and standard revision; base metals; process; diameter; package; quantity; WPS; testing; certificates; destination; service conditions. |
Final compliance is defined by the purchase order, approved drawing and issued mill documentation. Availability is confirmed for each grade, size and production route.
SAKY METAL reviews ER308 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: State whether the procedure calls for ER308, ER308L, ER308H or another variant. The suffix changes classification limits and cannot be omitted during procurement review.
Grade Designations and Cross-References
| Product designation | ER308 bare welding electrode / rod |
|---|---|
| AWS order reference | AWS A5.9/A5.9M ER308; confirm the required standard revision |
| GB/T cross-reference | H0Cr21Ni10 |
| JIS cross-reference | YS308 |
| DIN / European reference | 1.4316 |
| 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
- Austenitic stainless fabrication
- Process equipment and general assemblies
- Sheet, tube and pipe joining under a qualified WPS
- Shop and field welding by specified process
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.

ER308 Welding Wire FAQs
What is the difference between ER308 and ER308L?
They are separate classifications with different composition limits. Order the exact suffix required by the drawing, specification and WPS.
Which welding processes can use ER308 bare filler?
AWS A5.9 covers bare electrodes and rods used with processes such as GMAW and GTAW; the exact product form must match the procedure.
What should an ER308 RFQ include?
Include process, diameter, spool or rod package, classification and revision, quantity, inspection, certificate type and destination.
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.
