UNS N02200

Nickel 200 is commercially pure nickel. Nickel 201 (UNS N02201) is the low carbon, .02 max, version. Often, a heat lot is certified to both. Nickel 200 is magnetic except at extremely elevated temperatures. It is resistant to most acids and is used in the production of caustics. Nickel 200 is used in the food processing industry.

Heat Treatment

Nickel 200 may be annealed over a wide range of temperatures above its recrystallization temperature. For heavily coldworked material, temperature may be as low as 1100° to 1200°F (595° to 650°C), but from a practical viewpoint, the range is usually about 1300 to 1700°F (705° to 925°C).
