Corrosion Resistance

Nickel 200 is significantly resistant to a number of corrosive media.  While it is most useful in reducing environments, this nickel alloy can also be used under oxidizing conditions that result in the development of a passive oxide film. The exceptional resistance of this material caustic is essentially based on this type of protection. However, it is preferable to use Nickel 201 when temperatures above 315°C /600°F are involved, no matter the environment.


Nickel 200 can be machined adequately at commercial rates if certain viable practices are been followed. This nickel alloy has a tendency to flow under the pressure of the tool cutting edge, subsequently forming long stringy chips.  In some instances, people may use 40° to 45° rake angles for the machining process of this allow in order to avoid a built-up edge. Using high-speed cast-alloy or steel tools would be a good option for machining Nickel 200. In harder tempers, the chip action tends to be significantly better with this alloy, so that cold-drawn rod in the as-drawn or stress-relieved temper would provide an improvement over annealed material.

Hot and cold forming

  • Hot Forming: Nickel 200 can be hot formed easily to just about any shape. Using the ideal temperature during the process of deformation is the most crucial factor in achieving hot malleability. 650° to 1230°C/ 1200° to 2250°F is considered to be the ideal temperature range for hot forming this material.  More than the temperature of 870°C/1600°F should be used for all hot forging work as Nickel 200 may stiffen below this temperature. However, choosing to conduct light forging below the temperature of 650°C/1200°F would result in superior mechanical. 870° to 1230°C/1600° to 2250°F additionally would be the best temperature range for hot bending this material.  It is important to make sure to avoid heating this nickel alloy above the upper-temperature limit of 1230°C/2250°F, no matter the operation.
  • Cold Forming: Almost all conventional cold forming methods can be used for working on Nickel 200.  In most cases, this alloy would behave in a similar fashion as mild steel, excepting for the fact that due to the higher elastic limit of this material superior power would be necessary to perform the relevant operations. Hence, when it comes to manual operations like hand hammering and spinning, only limited shapes can be worked on it.  The assistance of frequent anneals to restore softness would be needed to conduct severe work manually.

 The major applications of Nickel 200

  • Handling of foods
