Nickel 200/201  │  UNS Number N02200/N02201

Nickel 200 and Nickel 201 are solid solution strengthened, commercially pure wrought materials with good mechanical properties 

over a wide range of temperatures and excellent resistance to many corrosives, in particular hydroxides. 

Nickel 201 was a modification of 200 to control carbon (.02 max) which keeps it from being embrittled by 

intergranular precipitates at temperatures of 600° F to 1400° F in many processes. 

Typically, the elemental restrictions of both, nickel 200 and nickel 201, are combined into one, 

dual-certified chemistry resulting in a single alloy with the desired characteristics of both alloys, Nickel 200/201. 

What are the characteristics of Nickel 200/201
