Depth Characteristics
- Caustic Alkali Champion: Excellent resistance to sodium and potassium hydroxide over a wide concentration and temperature range — proven in caustic evaporators operating above 300°C.
- Immune to Chloride SCC: Pure nickel does not suffer chloride-induced stress corrosion cracking, the classic failure mode of austenitic stainless steels.
- High Conductivity: Thermal conductivity near 70 W/m·K and low electrical resistivity make Ni 200 a preferred material for heat transfer and electronic components.
- Magnetic & Magnetostrictive: Ferromagnetic with high permeability and low coercivity, ideal for relays, solenoids and sonar/magnetostrictive transducers.
- Excellent Fabricability: Readily hot- and cold-worked, machined and welded with matching fillers (ENi-1 / ERNi-1), including for deep-drawn and spun parts.
Manufacturing Process — Melting & Forging
Nickel 200 is melted in electric furnaces (VIM/EAF) with strict control of carbon, sulfur and gaseous elements to preserve purity. Ingots are broken down by hot forging and rolling at 870–1230°C, then annealed at 705–925°C followed by water quenching to keep a soft, ductile, fully recrystallized structure. Bars are peeled and centerless-ground, tubes are cold-pilgered and pickled, and strip is bright-annealed in a protective atmosphere for superior surface finish. For service above 315°C, the low-carbon grade Ni 201 is recommended to prevent graphitization.

- Electronics & Instrumentation: Magnetostrictive transducers, relays, lead frames and precision electronic parts.
6+ Professional FAQs
1. What is the difference between Nickel 200 and Nickel 201?
The carbon content — 0.15% max for Ni 200 vs 0.02% max for Ni 201. For continuous service above 315°C, Ni 201 is required to avoid graphitization and subsequent embrittlement.
2. Is Nickel 200 magnetic?
Yes. Ni 200 is ferromagnetic with high magnetic permeability and low coercivity, which is exploited in relays, solenoids and magnetostrictive devices.
3. Where does Nickel 200 provide the best corrosion performance?
In reducing media: caustic alkalis, hydrofluoric acid, and dilute non-oxidizing acids. Avoid strong oxidizing acids such as nitric acid, which rapidly attack pure nickel.
4. What is the maximum service temperature?
Ni 200 is generally limited to about 600°C in air for structural parts; above 315°C, specify Ni 201 to prevent graphitization.
5. Can Nickel 200 be welded?
Yes — weldability is excellent using matching fillers ENi-1/ERNi-1 (Ni 207 consumables) with no preheat normally required.
6. Which product forms are available?
Round bar, plate, sheet, strip, seamless and welded tube/pipe, forgings, flanges and wire — all supplied with full traceability and EN 10204 3.1 certificates.
