More Content ▼
Nickel 200 is a commercially pure nickel alloy (UNS N02200) with a minimum nickel content of 99.0%. It is known for its excellent corrosion resistance, particularly in reducing and neutral environments. This material also offers good mechanical properties and high thermal and electrical conductivity. Additionally, Nickel 200 exhibits high ferromagnetic properties at room temperature. It also has a high Curie temperature. This means that it is a great option for those needing a strong corrosively resistant fastener with good magnetization properties for their specific application.
Key Properties of Nickel 200:
Both Nickel 200 and Nickel 201 are commercially pure nickel alloys with excellent corrosion resistance and similar mechanical properties. However, the main difference lies in their carbon content, which affects their performance at elevated temperatures.
| Property | Nickel 200 (UNS N02200) | Nickel 201 (UNS N02201) |
| Nickel Content | ≥ 99% | ≥ 99% |
| Carbon Content | ≤ 0.15% | ≤ 0.02% |
| Corrosion Resistance | Excellent in alkaline environments | Similar, but better in high-temp applications |
| Mechanical Strength | Higher due to more carbon content | Lower due to the carbon content |
| Graphitization | Higher risk at higher temperatures | Low risk, better at higher temperatures |
| Typical Applications | General industrial use, chemical processing, electrical components | High-temperature applications, chemical & food processing |
Our nickel 200 fasteners are often dual certified to both Nickel 200 (UNS N02200) & Nickel 201 (UNS N02201) specifications.
| Material | Key Similarities | Key Advantages | Best Application Areas |
| Nickel 201 | Chemically identical but lower carbon | Better high-temperature stability | Chemical processing, heat exchangers |
| Monel 400 | High nickel content, corrosion-resistant | Stronger, better in seawater | Marine, oil & gas, chemical plants |
| Hastelloy C-22 | Nickel-based, corrosion-resistant | Best for oxidizing & reducing conditions | Chemical reactors, acid handling |
| Inconel 600 | Nickel-chromium, heat-resistant | High strength, oxidation resistance | Aerospace, power plants, nuclear applications |
| Titanium Grade 2 | Corrosion-resistant, ductile | Lightweight, superior seawater resistance | Aerospace, medical, marine applications |
| Alloy 20 | Nickel-based, corrosion-resistant | Superior sulfuric acid resistance | Chemical processing, food, pharmaceutical applications |
