N02201 Commercially Pure Nickel Alloy Rod
Nickel 201 alloy is a commercially pure wrought alloy having properties similar to that of nickel 200 alloy, but with a lower carbon content to avoid embrittlement by inter-granular carbon at high temperatures.
It is resistant to acids and alkalis, and dry gases at room temperature. It is also resistant to mineral acids depending on the temperature and concentration of the solution.
Good resistance to corrosion in acids and alkalis and is most useful under reducing conditions.
Outstanding resistance to caustic alkalis up to and including the molten state.
In acid, alkaline and neutral salt solutions the material shows good resistance, but in oxidising salt solutions severe attack will occur.
Resistant to all dry gases at room temperature and in dry chlorine and hydrogen chloride may be used in temperatures up to 550C.
Resistance to mineral acids varies according to temperature and concentration and whether the solution is aerated or not. Corrosion resistance is better in de-aerated acid.
Nickel 201 can be hot formed to almost any shape. The temperature range 1200°F to 2250°F is recommended and should be carefully abided as the proper temperature is the most important factor in achieving hot malleability. Full information of the forming process should be sought and understood before proceeding.
Nickel 201 can be cold formed by all conventional methods, but because nickel alloys have greater stiffness than stainless steels more power is required to perform the operations.
Nickel 201 is the low carbon version of Nickel 200. It is preferred to Nickel 200 for applications involving exposure to temperatures above 600°F. With low base hardness and lower work-hardening rate, it is particularly suited for cold forming.
