Nickel 201, N4

General Description

Nickel 201 is a low carbon variety compared with Nickel 200, possessing low annealed hardness and a very low work-hardening rate, desirable for cold forming operations. It is highly resistant to corrosion by neutral and alkaline salt solutions, fluorine and chlorine, but in oxidizing salt solutions severe attack will occur.

The applications of pure nickel includes food and synthetic fiber processing equipment, electronic parts, aerospace and missile components, handling of sodium hydroxide above 300℃.
