    Features: Nickel 201 is the low-carbon version of Nickel 200. Because of its low carbon content, Nickel 201 is not subject to embrittlement by intergranularly precipitated carbon or graphite when exposed to temperatures of 315 to 760℃ for prolonged time if carbonaceous materials are not in contact with it. Therefore, it is a substitute for Nickel 200 in applications above 315℃. However it does suffer from intergranular embrittlement by sulfur compounds at temperatures above 315℃. Sodium peroxide can be used to change them to sulfates to counteract their effect.

    Applications: Electronic components, caustic evaporators, combustion boats and plater bars.
