The following are typical for annealed condition. | Property | Value (Annealed) | | :--- | :--- | | **Tensile Strength** | 345 - 485 MPa (50 - 70 ksi) | | **Yield Strength (0.2% Offset)** | 103 - 345 MPa (15 - 50 ksi) | | **Elongation (in 2")** | 40% - 55% | | **Hardness (Rockwell B)** | 45 - 70 HRB | --- ### **Key Characteristics & Advantages** 1. **Excellent Corrosion Resistance:** Resists corrosion by neutral and alkaline salts, fresh water, dry chlorine, hydrogen chloride, and most organic acids. It is particularly resistant to caustic alkalies across all concentrations and temperatures. 2. **High Thermal & Electrical Conductivity:** Its high purity gives it excellent conductivity, making it suitable for electronic and electrical components. 3. **Good Mechanical Properties:** Offers a good balance of strength and ductility, and can be readily cold-worked to higher strength levels. 4. **Low Magnetic Permeability:** Is essentially non-magnetic, a critical property for many electronic and scientific applications. 5. **Good Fabricability:** Can be easily fabricated and welded using common techniques suitable for nickel alloys. --- ### **Product Applications** Nickel 212 is used in a vast array of industries due to its versatility and reliability. * **Chemical Processing:** * Caustic soda (sodium hydroxide) production and handling equipment. * Reaction vessels, evaporators, and heat exchangers for organic synthesis. * Piping, valves, and pumps for handling various corrosive chemicals. * **Aerospace & Defense:** * Rocket engine components due to its performance in cryogenic temperatures. * Electronic chassis and housings requiring non-magnetic properties. * **Food & Pharmaceutical Processing:** * Equipment for fatty acid and soap manufacturing. * Components requiring high purity and resistance to product contamination. * **Electrical & Electronics:** * Transistor and capacitor components. * Lead wires, brackets, and other conductive parts. * **Other Applications:** * Marine engineering components. * Scientific and research equipment. * Heat exchanger tubes. --- ### **Important Note on High-Temperature Service** While Nickel 212 is excellent for many applications, it is susceptible to **carburization and embrittlement** in service environments above **315°C (600°F)** where carbon monoxide or other carburizing gases are present. For such high-temperature applications, **Nickel 201 (UNS N02201 / Werkstoff 2.4061 / DIN 17742)**, a low-carbon version of this alloy, is strongly recommended. ### **Summary** **Nickel 212 (Werkstoff 2.4110)** is a fundamental, high-purity nickel alloy that provides an optimal balance of corrosion resistance, manufacturability, and physical properties. Its standardization under DIN, ASTM, and other major systems makes it a globally recognized and trusted material for critical applications from chemical plants to advanced aerospace systems.
