Alloy 200

Introduction :

Nickel 200 and Nickel 201 are solid solution strengthened, commercially pure wrought alloys. The elemental restrictions of both alloys are combined into one, dual-certified chemistry, resulting in a single alloy with the desired characteristics of both alloys. When operating temperatures are expected to exceed 600°F, carbon content becomes critical. The lower carbon content of Nickel 201 makes the material resistant to graphitization and therefore less subject to embrittlement.

Industries & Applications

Nickel 200/201 is used heavily in the chemical and electronics industries. It is also used in the aerospace, petrochemical, power generation and marine/offshore engineering industries. Typical applications where Nickel 200/201 is used include electronic and electroplating components, caustic evaporators, food processing equipment, caustic handling and storage equipment, synthetic fiber production, salt production and other processes where sodium hydroxide and fluorine are used.

Features: Nickel 200 is commercially pure wrought nickel. It is highly resistant to various reducing chemicals. It can also be used in oxidizing conditions that cause the formation of a passive oxide film, for instance its unexcelled resistance to caustic alkalis. Nickel 200 is limited to service at temperatures below 315℃, because at higher temperatures it suffers from graphitization which results in severely compromised properties. In that circumstance, Nickel 201 is used instead. It has a high Curie temperature and good magnetostrictive properties. Its thermal and electrical conductivities are higher than nickel alloys.

Applications: Useful for applications where maintaining product purity is considered such as handling of caustic alkalis, foods and synthetic fibers; electrical and electronic parts; aerospace and missile components; and chemical storage and shipping tanks.
