Nickel 201 is a commercially pure alloy of nickel which is similar to alloy 200 but has lower carbon content. A lower carbon content is beneficial as it prevents embrittlement by the carbon atoms contained within at higher or elevated temperatures. Apart from mechanical uses, nickel 201 is also used for chemical processing.
Characteristics or properties of Nickel 201 Valves:
Corrosion resistant in acids as well as alkalis.
Protected from inter-granular attack at high or elevated temperatures.
It has a tensile strength of 45 N/mm sq.
Nickel 201 can be shaped into bars, pipes, plates or sheets.
Its minimum tensile strength is 70 mega Pascal.
Applications of Nickel 201 Valves:
Manufacture and handling of sodium hydroxide.
Production of soap and rayon.
Production of monomers, especially vinyl chloride.
Used in reactors where fluorine is produced.
Aniline hydrochloride production also involves the use of nickel 201.
