Nickel Alloy 201 Introduction to Characteristics and Execution Standards

Nickel Alloy 201 Introduction to Characteristics and Execution Standards

Common Trade Names: Nickel 201, LC Nickel 99.2; Alloy 201

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.

Available Product Forms: Pipe, tube, sheet, strip, plate, round bar, flat bar, forging stock, hexagon and wire.

Specifications:Nickel 201 is designated as UNS N02201 and Werkstoff Numbers 2.4061 and 2.4068.
