Difference Between Nickel Alloy 200 and 201 Flanges
| Property | Nickel 200 Flanges | Nickel 201 Flanges |
|---|---|---|
| UNS Number | N02200 | N02201 |
| Nickel Content | 99.0% Minimum | 99.0% Minimum |
| Carbon Content | Up to 0.15% | Up to 0.02% |
| High-Temperature Performance | Suitable for moderate elevated temperatures. | Preferred for temperatures above 600°F (315°C) due to lower carbon content. |
| Graphitization Resistance | Moderate resistance. | Superior resistance to graphitization during prolonged high-temperature exposure. |
| Corrosion Resistance | Excellent resistance to alkalis, caustic solutions, and reducing environments. | Similar corrosion resistance with improved stability at elevated temperatures. |
| Mechanical Properties | High ductility and toughness. | Slightly lower strength but improved long-term thermal stability. |
| Weldability | Excellent | Excellent |
| Typical Applications | Chemical processing, food handling equipment, caustic soda plants, and electronics. | Heat exchangers, evaporators, petrochemical equipment, and high-temperature processing systems. |
Selection Guide: Nickel 200 flanges are widely used for general corrosion-resistant applications involving caustic alkalis and reducing chemicals. Nickel 201 flanges contain lower carbon content, making them the preferred choice for elevated-temperature service where resistance to graphitization and long-term thermal stability are critical.
