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.

Fabrication with Nickel 200/201

All hot working and cold working practices can be utilized when shaping Nickel 200/201. Hot working temperatures should be between 1200° F and 2250° F with heavy forming to be performed at temperatures above 1600° F. Annealing should be performed at a temperature between 1300° F and 1600° F. Care should be taken when choosing the anneal temperature and time at temperature for this can greatly influence the mechanical properties and structure of the material.

Nickel 200/201 can be easily welded by conventional welding, brazing, and soldering processes with the exception of the oxyacetylene process.
