2.4061 is the low-carbon version of commercially pure (99.0% minimum) wrought nickel, developed specifically for service at elevated temperatures where the standard grade would embrittle. This datasheet presents the material within the European (DIN / EN / Werkstoff-Nummer / VdTÜV) standard system.
It is essentially identical to Nickel 200 but with the maximum carbon content reduced to 0.02% (versus 0.15%). This low carbon level gives virtual immunity to intergranular embrittlement from grain-boundary graphite precipitation above about 315 °C (600 °F), so the grade is preferred over Nickel 200 for all sustained service above this temperature. The reduced carbon also lowers the base hardness and work-hardening rate and raises ductility, making the material particularly well suited to spinning and severe cold forming.
It retains the outstanding resistance of pure nickel to caustic alkalies (up to and including the molten state), good resistance in acid, alkaline and neutral salt solutions, and excellent resistance to chloride-ion stress-corrosion cracking. It is ferromagnetic with high thermal and electrical conductivity. In dry chlorine and hydrogen chloride it may be used to about 550 °C. Typical applications include caustic evaporators, food-processing equipment, chemical shipping drums, electronic and electroplating components, combustion boats, rocket-motor cases and magnetostrictive devices. The presence of chlorates should be kept to a minimum, as they accelerate attack.

Low-carbon commercially pure nickel; strengthened only by cold work (not age-hardenable). Heat treatment is for annealing / stress relief.
Anneal Temperature: 704–871 °C (1300–1600 °F), time depending on section and prior cold work Purpose: softening and recrystallisation after cold work.
Key advantage: because of the low carbon content (0.02% max), Nickel 201 is virtually immune to grain-boundary graphitisation and intergranular embrittlement above ~315 °C, and is therefore the grade of choice for sustained elevated-temperature service where Nickel 200 would degrade.
Readily joined by welding, brazing and soldering — easily welded and processed. The low carbon content is beneficial for elevated-temperature welded service.
| Welding Process | Applicability | Filler / Consumable |
|---|---|---|
| GTAW / TIG · GMAW / MIG | Excellent | EN ISO 18274 matching Ni filler (LC-Ni type) |
| SMAW / stick | Good | Matching Ni electrode |
| Brazing / soldering | Suitable | Appropriate brazing alloys |
Clean joints thoroughly before welding; avoid sulphur-bearing marking materials and lubricants, which embrittle nickel at temperature.
