  • Excellent heat resistance strong alkali corrosion
  • For carbonate, nitrate, oxides and acetic acid salt and other salt, alkaline and neutral solution medium, good corrosion resistance
  • Fatty acid’s corrosion resistance
  • Nickel 201 is the low-carbon version of Nickel 200. Because of its low carbon content, Nickel 201 is not subject to embrittlement by intergranularly precipitated carbon or graphite when exposed to temperatures of 315 to 760℃ for prolonged time if carbonaceous materials are not in contact with it. Therefore, it is a substitute for Nickel 200
