NICKEL-ALLOY FILLER METAL · TECHNICAL SOURCING
ERNiCrMo-3 Nickel-Alloy Welding Consumables
Technical sourcing of ERNiCrMo-3 solid wire and rods against current AWS and ISO classification, welding-procedure and documentation requirements.
MNK-G.S.A coordinates specialist nickel-alloy welding consumables for corrosion-resistant fabrication, repair, overlay and dissimilar-joint inquiries after technical review.
Classification Identity
- AWS A5.14/A5.14M:2026 is the current AWS specification for nickel and nickel-alloy bare welding electrodes and rods; it revises the now-historical 2024 edition.
- A current manufacturer catalogue maps AWS A5.14 ERNiCrMo-3 to ISO 18274 S Ni 6625 (NiCr22Mo9Nb) for a referenced solid-wire product.
- ISO 18274:2023 is the current international classification framework for solid nickel-alloy wire electrodes, strip electrodes, wires and rods.
- The filler classification alone does not approve a joint between Alloy 625, another nickel alloy, stainless steel or carbon steel.
Standards and Supply Definition
| AWS classification | AWS A5.14/A5.14M:2026 — ERNiCrMo-3 |
| International classification | ISO 18274:2023 — S Ni 6625 (NiCr22Mo9Nb), verified for a referenced manufacturer product |
| Supply definition | GMAW/MIG wire or GTAW/TIG rod, as produced and certified |
| Application review | Base materials, dilution, service corrosion, joint design, PWHT and governing code |
| Ordering controls | Process, diameter, package, batch, approvals, certificate, quantity and destination |
Application Context
Manufacturer literature places ERNiCrMo-3 in corrosion-resistant NiCrMo filler applications associated with Alloy 625. It may also be considered for specific dissimilar joints or overlays only when the approved procedure and governing specification permit. Base-material identity, dilution, heat treatment and service environment must be reviewed.
RFQ and Quality Controls
- Both base-material grades and product standards
- Joint or overlay purpose, dilution limit and service environment
- Approved WPS/PQR, process, diameter and package
- Required mechanical, corrosion, class or OEM acceptance
- Batch certificate, traceability, quantity and destination

The ISO mapping and application context are manufacturer-specific. MNK verifies the exact quoted product, documentation and approved welding procedure before order.
Relevant ISO Reference
Use the current authorised ISO publication together with the governing specification, manufacturer documentation and project requirements. A reference link alone does not establish grade equivalence, product compliance or application approval.
