Description
NICKEL-201
Low-carbon nickel is known as Nickel 201 (UNS N02201/W.Nr. 2.5061, 2.4068), which is also known as Nickel 200. These include caustic evaporators, combustion boats, plater bars, and electronic parts. Nickel 201, because it has a low base hardness and a slow rate of work hardening, is good for spinning and cold forming. It is better than Nickel 200 for applications where the metal will be exposed to temperatures above 600°F (315°C). In acidic and alkaline environments, it has good corrosion resistance. It is most useful in reducing conditions. A lot of resistance to caustic alkalis up to and even in the molten state.
Acid, alkaline, and neutral salt solutions are all good for the material, but oxidising salt solutions will cause a lot of damage. At room temperature, it is resistant to all dry gases. Dry chlorine and hydrogen chloride can be used in dry chlorine and hydrogen chloride up to 550 °C. Resistance to mineral acids changes based on the temperature and concentration of the solution, as well as whether or not the solution is aerated or not. Acid that has been de-aerated is more resistant to corrosion than acid that hasn't been mixed with air. Intergranular attack is almost impossible above 315 °C, so chlorates must be kept to a minimum.
