High-Chromium-Nickel Filler Metal
ER310 wire for heat-resistant stainless assemblies under a qualified procedure
ER310 is a high-chromium, high-nickel austenitic stainless filler-metal classification used in heat-resistant alloy fabrication when called out by the welding procedure. Elevated-temperature suitability depends on the complete joint design, base metal, thermal cycling, atmosphere, stress and code requirements—not the filler designation alone.
ClassificationER310
Primary useHeat-resistant stainless fabrication
Supply routeSpool wire & cut rods
Request ER310 heat-resistant stainless steel welding wire by standard, size and finish, with inspection and mill test certificates from SAKY METAL.

ER310 Heat-Resistant Stainless Steel Welding Wire | YS310 | DIN 1.4842 ER310 is a high-chromium, high-nickel austenitic stainless filler-metal classification used in heat-resistant alloy fabrication when called out by the welding procedure. Elevated-temperature suitability depends on the complete joint design, base metal, thermal cycling, atmosphere, stress and code requirements—not the filler designation alone.
| Material / grade | ER310; GB/T H0Cr26Ni21; JIS YS310; DIN 1.4842 |
|---|---|
| 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 | Furnace and heat-treatment equipment; Heat-resistant stainless fabrications; High-temperature process components; Thermal equipment repair under an approved WPS |
| 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 ER310 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 maximum and continuous operating temperatures, atmosphere, thermal cycles and base-metal grades. Creep or oxidation performance must be evaluated at the welded-joint level.
Grade Designations and Cross-References
| Product designation | ER310 bare welding electrode / rod |
|---|---|
| AWS order reference | AWS A5.9/A5.9M ER310; confirm the required standard revision |
| GB/T cross-reference | H0Cr26Ni21 |
| JIS cross-reference | YS310 |
| DIN / European reference | 1.4842 |
| 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
- Furnace and heat-treatment equipment
- Heat-resistant stainless fabrications
- High-temperature process components
- Thermal equipment repair under an approved 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.

ER310 Welding Wire FAQs
Is ER310 automatically suitable for every high-temperature joint?
No. Service atmosphere, stress, thermal cycling, base metal and code rules must be evaluated before approval.
What service data should be included in an ER310 enquiry?
Provide base metals, design and peak temperatures, atmosphere, cycling, process, diameter, package, WPS and inspection requirements.
Can ER310 be supplied for GMAW and GTAW?
Spool wire and straight rod forms can be reviewed, subject to the requested diameter, package and classification.
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.
