Introduction

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

This means that you receive 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 is used in such applications as fluorine and sodium hydroxide production as well as heat exchangers and pressure vessels.

Key Features:

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:

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

Cold Working

The tensile properties can be significantly enhanced by cold working.

Weldability

Can be joined by a wide variety of processes including inert gas welding processes, resistance welding, soldering and brazing.
