Nickel 201 丨 UNS N02201

Nickel 201 is a commercially pure (99.6%) wrought nickel essentially the same as Nickel 200 but with a lower carbon content to prevent embrittlement by intergranular carbon at temperatures over 600°F (315°C). Lower carbon content also reduces hardness, making Nickel 201 particularly suitable for cold-formed items.

Nickel 201 / UNS N02201 / W.Nr 2.4061, 2.4068

Applications:

Nickel 201 is widely used in chemical processing, food manufacturing, tanks for fluorine production, storage and transport of phenol, synthetic fiber production, caustic soda production, hydrogen chloride production, electrical and electronic components, marine engineering, and medical devices.

Normal product forms: Pipes, tubes, sheets, strips, plates, bars, forgings, hexagons, and wires.
