A material which has commercially pure Nickel (99.6%) is nickel 200 tube. It has excellent mechanical properties inherited and shows good resistance to most of the corrosive environments. Adding to this, this alloy is magnetic. It also has high thermal properties and has good electric conductivity.
Excellent corrosion resistance properties exhibited by this material makes it useful for maintaining purity in food handling, synthetic fibres, and alkalis. These are the main reasons why it is applicable in industries such as chemical shipping, electronic, aeronautics and missile components.
In industrial level, both nickel 200 tubing and ni201 are used more frequently. Although both materials comprise higher contents of Nickel and as a result, exhibit excellent corrosion properties, both have some distinguishing differences. The main difference lies in their chemical composition. Though composed of Nickel, ni201 contains low carbon or is a low-carbon of ni-200. This material only contains 0.02% Carbon (maximum).
200 Nickel tubing is utilized in scenarios where temperature is under 600° F. Whereas 201 Nickel tubing is utilized in areas with temperature above 600° F. This is one of the reasons why it is good for cold forming as it requires high temperature. On the other hand, electronic industries majorly demand for Ni200 extruded tube. It is also demanded in chemical industries, aeronautics and missile equipment, which require high corrosion resistance to be a primary factor.

Characteristic properties are shown by nickel 200 seamless tube which make itself unique for utilization. Along with corrosion resistance properties, this material is subjected to temperatures at the range of 700-1100° F. When exposed to higher temperatures, it affects the atomic structure as a result of prolonged heating of amorphous Carbon, in other words, graphitization.
This becomes one of the reasons for the birth of compromised properties.

Along with corrosion resistance, there are much other appreciable properties which are executed by alloy 200 welded tube. They are known to exhibit good mechanical properties; they have good conductivity towards electricity and high-thermal situations.
They are also resistant towards most of the corrosive environments. Adding to this, technique such as Tungsten Inert Gas, is a well-known welding technique by which this material can be easily welded. They have low carbon content. As a result, it minimizes precipitation of boundary grain during the process of welding, which in turn, reduces the risk of subsequent corrosions.
Due to the rearrangement of atomic structures which achieves a structure that is typical of solids, as a result of prolonged heating of amorphous carbon, UNS N02200 annealed tube is not recommended for high temperatures. This issue occurs mainly when the material is exposed to high temperatures.
For high temperatures, Nickel 201 is used. But for temperature below 600° F, 200 Nickel then becomes an ideal use case. This is one of the reasons why industries such as pressure vessel services, do not use this material as they require temperature up to 1250 ° C.
Because of good corrosion resistance to almost all corrosive scenarios or environments, alloy 200 heat exchanger tube can be used in variety of industries and it provides good results. Following are the four uses of this product:
