Nichel 201
Nickel 201 is the low-carbon version of Nickel 200. Its extremely low carbon content (0.02% max) prevents embrittlement by intergranular carbon at elevated temperatures, making it the required choice for service above 600°F (315°C).
- Forme comuni: Plate, Sheet, Strip, Pipe, Tube, Bar, Wire.
- Caratteristiche principali: Resistance to graphitization and embrittlement at high temperatures.
- Physical Prop: High electrical and thermal conductivity; ferromagnetic.
- Temperature Limit: Preferred for service **above** 600°F (315°C).
While Nickel 201 shares the excellent corrosion resistance of Nickel 200, it should be specified for any application operating continuously above 600°F (315°C). The low carbon content is critical to maintaining ductility and avoiding premature failure in high-temperature caustic and electronic applications.
Stabilità alle alte temperature
The primary advantage over Nickel 200. It remains ductile and tough where Nickel 200 would become brittle due to carbon precipitation.
Caustic Resistance at Temp
Ideal for evaporators, reactors, and piping systems handling concentrated caustic soda at temperatures well above 600°F (315°C).
Electronic Purity
Used for electronic components that see high operating temperatures, such as anodes, cathodes, and magnetostrictive devices.
