ASTM B829 B751 Nickel 200 Tube UNS N02200 Ni 99.0 Diameter 50.8mm Wall Thickness 1.65mm
Nickel 200 ASTM B163 UNS N02200 Ni 99.0 Nickel Alloy Seamless Pipe Nickel Tubing Diameter 50.8mm Wall Thickness 1.65mm
Features: Nickel 200 is commercially pure wrought nickel. It is highly resistant to various reducing chemicals. It can also be used in oxidizing conditions that cause the formation of a passive oxide film, for instance its unexcelled resistance to caustic alkalis. Nickel 200 is limited to service at temperatures below 315℃, because at higher temperatures it suffers from graphitization which results in severely compromised properties. In that circumstance, Nickel 201 is used instead. It has a high Curie temperature and good magnetostrictive properties. Its thermal and electrical conductivities are higher than nickel alloys.
