Classification
| AWS class | ER NiCr-3 |
|---|---|
| EN ISO class | SG - NiCr20Mn3Nb (S Ni 6082) |
| Material no. (W.-Nr.) | 2.4806 |
| Other standards | ISO 20172: Gruppe 8.1 |
Purpose
- Solid Ni-Cr-Fe rod (alloy 82) for joining NiCr alloys, heat-resisting austenitic steels and dissimilar-metal welds.
- Service from -196°C to +550°C continuous; scale resistant to 1000°C.
Why it works
The Ni-Cr base with niobium addition (Nb ~2.5%) stabilizes the deposit against chromium carbide precipitation in the heat-affected zone, avoiding the intergranular sensitization typical of welding nickel alloys — hence its preferred use in dissimilar joints where base metal composition changes across the weld.
Fields of application
- Joining NiCr alloys (2.4816/2.4817, Inconel 600 type) and heat-resisting austenitic steels.
- Dissimilar-metal welding: stainless to carbon steel or to nickel alloys, in high-temperature process equipment.

Equivalence refers to the classification (AWS / EN ISO), not to product identity. In applications with a qualified procedure (WPS), validate the substitution before use.

Advantages
- Very wide service range: -196°C to +550°C continuous, scale resistant to 1000°C.
- Low carbon content (0.02%) — reduces carbide precipitation risk in the HAZ.
Limitations
- Not an alloy for concentrated-acid service — see NIC 625 or NIC 276 for that duty.
