Hastelloy® C-22 (Alloy 22, UNS N06022, Werkstoff Nr. 2.4602)

Hastelloy C-22 (also known as Alloy 22) is a Nickel-Chromium-Molybdenum-Tungsten alloy engineered to resist the most aggressive chemical environments. It offers outstanding resistance to both oxidizing and reducing media, making it one of the most versatile corrosion-resistant alloys available today.

It is widely used in industries where protection from pitting, crevice corrosion, and stress corrosion cracking is critical.

Key Features of Hastelloy® C-22

  • Excellent resistance to oxidizing and reducing environments

  • Superior protection against chlorides, wet chlorine gas, and mixed acid systems

  • Outstanding performance in pitting, crevice corrosion, and stress corrosion cracking

  • Retains corrosion resistance in the as-welded condition

  • High mechanical strength with excellent ductility

Applications

Hastelloy C-22 is used in critical industries including:

  • Chemical Processing: Chlorination, sulphonation, and acid-handling plants

  • Pollution Control: Flue gas scrubbers, waste treatment, environmental control units

  • Marine & Offshore: Seawater systems, brine-handling pipelines, offshore platforms

  • Nuclear & Power Generation: Fuel reprocessing, high-temperature corrosive environments
