What’s up guys? This is Michael with Michael Talks Metal back for some what? Metal talks baby! So let’s do this!
Today we are taking a look at commercially pure Nickel 200 and 201. If you find yourself appreciating the content, help the channel and smash that like button or even better, subscribe if you haven’t yet to do so. Thank you and we appreciate the support! Back to Nickel 200 and 201, and NO it’s not THAT type of Nickel but CP Nickel, CP meaning Commercially Pure. The UNS designations for the chemical compositions are UNS N02200 and UNS N02201 respectively.
CP Nickel has excellent corrosion resistance in atmospheric and marine environments and is also highly resistant to many reducing chemicals and caustic alkalies.
It has high thermal conductivity for heat transfer applications requiring corrosion resistance. CP Nickel has high electrical conductivity and useful magnetic and magnetostrictive properties. The magnetic properties are beyond the scope of this video, but let us know if we should discuss it in a future video.
While not hardenable by heat treatment, strength can be increased by cold work. CP Nickel is easily fabricated by all common metal working methods. The lower carbon content of 201 results in lower yield and tensile strengths as compared to 200.
Applications include food processing, chemical processing, electrical, electronic, thermal transfer, and aerospace components.
Nickel 200 is generally limited to applications at 600 deg F and below due to graphitization at higher temperatures. The lower carbon content of 201 extends its applications to temperatures as high as 1250 deg F .
CP Nickel is recognized for applications in the ASME Boiler and Pressure Vessel code.
