Features:
UNS Number N02201
Nickel 201 is the low-carbon version of Nickel 200. Because of its low carbon content, Nickel 201 is not subject to embrittle by intergranularly precipitated carbon or graphite when exposed to temperatures of 315 to 760℃ for prolonged time. Therefore, Nickel 201 is a substitute for Nickel 200 in Applications above 315℃. However, Nickel 200 also 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:
Nickel 201 is applied in Electronic components, caustic evaporators, combustion boats and plater bars.
