Alloy 200 / Alloy 201

Nickel Alloy

Alloy 200 / 201 Nickel Alloy

Alloy 200 & Alloy 201 are nickel alloys which have been combined into one with dual certified chemistry.

Dual Solution

The result is an alloy which benefits from the required characteristics from both alloys in a single solution. Alloy 200/201 offers exceptional resistance to caustic alkalis and good mechanical properties over a wide temperature range. The alloy finds use in such applications as fluorine and sodium hydroxide production as well as heat exchangers and pressure vessels.


Alloy 200 / 201 is similar in strength to mild steel in the annealed condition. The alloy offers exceptional resistance to caustic alkalis and good corrosion resistance in neutral and moderately reducing environments. Alloy 200/201 displays good mechanical properties over a wide temperature range.

Typical Applications

Commercial applications for this engineering material include:

  • Food processing
  • Fluorine generation
  • Heat exchangers
  • Tank heads
  • Chemical processing & storage
  • Phenol storage & transportation
  • Sodium hydroxide production
  • Pressure vessels & vessel components

We stock Alloy 200 / 201 in round bar, sheet, strip, round tube and hollow bar.
