Nickel 201:
- Nickel 201 is commercially pure (99.6%) wrought nickel and a low carbon version of Nickel 200. It has good mechanical properties and excellent resistance to many corrosive environments. Other useful features: high thermal and electrical
- conductivities, low gas content and low vapor pressure. The corrosion resistance makes it particularly useful for maintaining product purity in the handling of foods, liquids, synthetic fibers, and caustic alkali's.
High-temperature and Corrosion Resistance properties:
- Nickel 201 has the excellent corrosion resistance characteristic of Nickel 200. Because it is a low-carbon material (0.02% max.), Nickel 201 is not subject to embrittlement by interplanetary precipitated carbon or graphite when held at temperatures of 315° to 760 °C for extended times, provided carbonaceous materials are not in contact with it. It is, therefore, preferred to Nickel 200 in all cases where temperatures exceed 315 °C. Nickel 201 is ideal for laboratory crucibles which are capable of withstanding oxidizing furnace atmospheres up to 1100 °C. Above 300 °C its mechanical properties change: tensile strength falls, elongation grows making for example a crucible more malleable when handling or when heated by a direct flame.
- This can lead to a change in the profile/shape of a crucible.
- The material is subject to intergranular embrittlement by sulfur compounds at temperatures above 315 °C.
Water Properties:The resistance of Nickel 201 to corrosion by distilled and natural waters is excellent since resistant to water containing hydrogen sulphide or carbon dioxide. Nickel 201 gives excellent service in seawater.
