What are Nickel 200 / 201 Flanges?

Nickel 200 and Nickel 201 flanges are piping components made from commercially pure wrought nickel. These flanges are widely used to connect pipes, valves, pumps, and other equipment in systems that require excellent corrosion resistance and high thermal conductivity.

Nickel 200 and 201 are nearly identical, with the main difference being carbon content. Nickel 201 has lower carbon, making it more suitable for high-temperature applications.

Key Functions:

  • Provide strong and leak-proof pipeline connections
  • Allow easy assembly, maintenance, and inspection
  • Ensure safe handling of corrosive media
  • Enhance system flexibility and durability

These flanges are ideal for industries where purity and resistance to corrosive environments are critical.


Chemical Composition of Nickel 200 / 201

Nickel 200:

  • Nickel (Ni): ≥ 99.0%
  • Copper (Cu): ≤ 0.25%
  • Carbon (C): ≤ 0.15%
  • Manganese (Mn): ≤ 0.35%
  • Silicon (Si): ≤ 0.35%

Nickel 201:

  • Nickel (Ni): ≥ 99.0%
  • Carbon (C): ≤ 0.02% (Lower than Nickel 200)
  • Other elements similar to Nickel 200

Key Difference: Nickel 201’s lower carbon content reduces the risk of graphite formation at high temperatures, making it more suitable for elevated temperature applications.
