ERNiCrFe-12 Nickel Alloy Welding Wire
ERNiCrFe-12 is a nickel-chromium-iron bare welding wire and rod classified under AWS A5.14/A5.14M. It is selected for joining and overlay welding of high-temperature nickel alloys, including Alloy 602 CA-type materials, where oxidation resistance, carburization resistance and weld-metal stability are important.

Typical Chemical Composition
Composition limits must be confirmed against the ordered edition of AWS A5.14/A5.14M and the material certificate. The following values are typical for the ERNiCrFe-12 / Ni 6025 filler-metal family.
| C | Mn | Fe | Si | Ni | Cr | Al | Ti |
|---|---|---|---|---|---|---|---|
| 0.15–0.25 | ≤0.50 | 8.0–11.0 | ≤0.50 | Balance | 24.0–26.0 | 1.8–2.4 | 0.10–0.20 |
Welding and Application Guidance
| Application | Why ERNiCrFe-12 Is Considered |
|---|---|
| High-temperature furnace components | High chromium and aluminium support oxidation and carburization resistance. |
| Petrochemical and heat-treatment equipment | Used for compatible nickel-alloy joints and overlays exposed to elevated temperature. |
| Dissimilar-metal welding | May be considered for approved nickel-alloy-to-steel combinations after welding-procedure qualification. |
| Repair and overlay work | Provides a nickel-alloy weld deposit for heat- and corrosion-resistant surfaces. |
Actual filler-metal selection, preheat, interpass temperature, shielding gas and post-weld treatment must follow the base materials, service conditions and qualified welding procedure. Mechanical properties depend on the welding process and procedure; therefore, they should not be represented by a single universal value.
Inspection and Quality Documentation
| Chemical composition | Heat or batch analysis checked against the specified classification. |
| Dimensions and finish | Diameter, straightness, spool winding and surface condition inspected before packing. |
| Identification | Classification, heat/batch number and package identification maintained for traceability. |
| Additional testing | Deposited-metal testing or project-specific inspection can be reviewed with the purchase specification. |
Packaging
Straight rods are protected in sealed tubes or boxes, while MIG wire is supplied on identified spools with moisture-resistant wrapping and export cartons or wooden cases. Package labels can include classification, diameter, batch number, net weight and purchase-order reference.
