Nickel processed materials N02201

Classification：UNS N02201

Ultra-Low Carbon Property
- Carbon content ≤0.02%, preventing carbide precipitation and intergranular corrosion at temperatures above 316°C, suitable for long-term high-temperature service.
Exceptional Physical Properties
- High Thermal & Electrical Conductivity: Thermal conductivity ~70 W/m·K, low resistivity (0.096 μΩ·m), ideal for electronic components and heat dissipation parts.
- High-Temperature Stability: Melting point 1435–1445°C, stable mechanical properties below 815°C with outstanding creep resistance.
Corrosion Resistance
- Alkaline Environments: Corrosion rate of only 0.03 mm/y in boiling 60% NaOH, far superior to stainless steel (e.g., SUS 304: 13.3 mm/y).
- Reductive Media: Resistant to HCl, H₂SO₄ (non-oxidizing), and HF, but vulnerable to strong oxidizers like HNO₃.
Flexible Mechanical Performance
- Annealed state: Tensile strength ≥345 MPa, elongation ≥30%.
- Cold-worked state: Strength exceeds 800 MPa, suitable for stamping, spinning, and forming processes.

Traditional Industries
- Chemical Equipment: Evaporators for caustic soda in chlor-alkali industries, sulfuric acid pipelines, and high-temperature corrosion-resistant tubing in oil & gas.
- Food & Pharmaceutical: High-purity food-grade equipment (e.g., salt refining systems) to avoid metal ion contamination.
- Aerospace: Rocket engine injectors, high-temperature sensor housings.
New Energy Sectors
- Batteries & Fuel Cells
  - Li-ion Battery Tabs: Utilizes high conductivity (9.5 μΩ·cm) and electrolyte corrosion resistance.
  - Fuel Cell Bipolar Plates: Excellent acid resistance in PEMFC environments.
- Nuclear Energy: Reactor structural components (control rods, coolant pipes) with reduced neutron embrittlement risks.
- Solar Thermal Power: Chloride-resistant molten salt heat storage systems.
- EV & Energy Storage: Battery enclosures and heat sinks (lightweight density: 8.9 g/cm³).
