What Are Nickel 200/201 Pipes & Tubes?

Nickel 200/201 Pipes & Tubes are hollow cylindrical products manufactured from commercially pure nickel.

  • Nickel 200 (UNS N02200): Contains higher carbon content and offers good mechanical strength.
  • Nickel 201 (UNS N02201): Low carbon version of Nickel 200, providing improved resistance to graphitization at elevated temperatures.

Nickel 201 is preferred for applications above 315°C where carbon content must be minimized.

Key Features of Nickel 200/201 Pipes & Tubes

  • Excellent resistance to corrosion in alkaline environments
  • Outstanding resistance to caustic soda and alkalis
  • Good mechanical strength
  • High thermal and electrical conductivity
  • Excellent ductility and formability
  • Good weldability
  • Resistant to stress corrosion cracking

These properties make Nickel 200/201 ideal for highly corrosive industrial applications.
