Nickel Nickel 200

Annealing Procedure

Annealing at 1500 F as a typical temperature. Annealing may be done within the range of 1700 F to 1300 F depending upon the degree of cold working and time at temperature.

Applications

Electronic parts, resistance to corrosion applications such as handling alkaline solutions and foods.

Cold Workability

Cold working may be accomplished using standard tooling as for plain carbon steels. More power is required as the nickel material has a higher elastic limit than steel and thus resists deformation.

Forgeability

Forging may be done at 2250 F to 1700 F.

Formability

Nickel is readily formed by all of the conventional means. It behaves in a similar fashion to plain carbon steel, except that more power is required to form nickel.

Hardening Procedure

Hardens due to cold working only.

Heat Treatability

Anneal at 1500 F to 1300 F and air cool.

Hot Workability

Hot working may be done in the range of 2200 F to 1200 F.

Machinability

Commercially pure nickel is soft and "gummy" to machine. However it can be machined with standard tooling. High-speed-steel tools work better than carbide tooling and it is important to maintain a high positive rake angle on cutting tools.

Principle Design Features

Commercially pure (99%) wrought nickel, basically unalloyed but containing minor amounts of other elements usually totaling less than 1%.

Weldability

All of the conventional welding and joining methods work with nickel. In particular the shielded metal-arc, gas tungsten-arc and gas metal-arc welding methods are recommended. Use nickel filler wire or electrodes.
