Nickel-Chromium-Molybdenum Filler
ERNiCrMo-3 wire for nickel-alloy, dissimilar and overlay procedures
ERNiCrMo-3 is a nickel-chromium-molybdenum bare filler-metal classification under AWS A5.14. It is commonly associated with Alloy 625-type welding, dissimilar joints and corrosion-resistant overlays. Filler selection must account for dilution, base-metal chemistry, service media, temperature, joint restraint and the governing fabrication code.
ClassificationERNiCrMo-3
Primary useAlloy 625-type, dissimilar and overlay welding
Supply routeSpool wire & cut rods
Request ERNiCrMo-3 nickel alloy welding wire with the required standard, dimensions, tolerance, finish, inspection and mill test certificates from SAKY METAL.

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 ERNiCrMo-3 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 both base metals and whether the operation is joining, buttering or overlay. For corrosion service, provide medium, concentration, contaminants, temperature and cleaning cycle.
Grade Designations and Cross-References
| Product designation | ERNiCrMo-3 bare welding electrode / rod |
|---|---|
| AWS order reference | AWS A5.14/A5.14M ERNiCrMo-3; confirm the required standard revision |
| GB/T cross-reference | HNS3306 |
| JIS cross-reference | NCF625 |
| DIN / European reference | 2.4831 |
| Alloy-family reference | N06625 alloy-family cross-reference |
| 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
- Nickel-alloy fabrication and repair
- Dissimilar nickel-to-stainless or steel joints
- Corrosion-resistant weld overlay
- Chemical, offshore and power-industry 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.

ERNiCrMo-3 Welding Wire FAQs
Is ERNiCrMo-3 the same thing as UNS N06625 base metal?
ERNiCrMo-3 is a welding-filler classification; N06625 identifies an alloy family. They are related cross-references, not identical purchase specifications.
Can ERNiCrMo-3 be used for dissimilar joints?
It is commonly evaluated for dissimilar welding, but the exact base-metal pair, dilution, service and WPS must be approved.
What corrosion-service data is needed?
Provide chemical medium, concentration, chlorides or contaminants, temperature, pressure, flow, cleaning cycle and expected exposure.
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.
