Nickel 201
Material Data Sheet
Nickel 201 only differs from Nickel 200 by its carbon content (.02% max in Ni 201 versus .15% max in Ni 200). This slight drop in carbon allows Nickel 201 to be utilized in higher temperature applications (over 600°F) to prevent embrittlement by inter-granular carbon at such elevated temperatures. Nickel 200 is virtually immune to intergranular attack above 315 degrees C but chlorates must be kept to a minimum.
Nickel 201 exhibits outstanding resistance to caustic alkalis up to and including the molten state. In acid, alkaline, and neutral salt solutions the material shows good resistance, but in oxidizing salt solutions, a severe attack will occur.
Other useful features of Nickel 201 are its magnetic and magnetostrictive properties, low gas content, and low vapor pressure. The chemical composition is shown below. The corrosion resistance of Nickel 201 makes it particularly useful for maintaining product purity in the handling of foods, synthetic fibers, and caustic alkalies, but also in structural applications where resistance to corrosion is of primary consideration.
