Perfect for applications in the Chemical Processing Industry

Alloy 22 can be used in a variety of applications, here are just a few examples:

  • Reactors and pressure vessels
  • Nutsche pressure filters
  • Centrifugers and dryers
  • Agitators and mixers
  • Containment vessels and glove boxes
  • Pollution control equipments
  • Flue gas desulphurisation (FGD) lined ducts and dampers

About Alloy 22

Due to its high nickel content, Alloy 22 is immune to chloride-induced stress corrosion cracking.

The alloy demonstrates outstanding resistance to pitting and crevice corrosion particularly in high chloride containing environments.

Alloy 22 has exceptional resistance to a large range of chemical process environments, including ferric chlorides, chlorine, hot contaminated solutions, acetic acids, seawater and brine solutions. Alloy 22 is the ideal choice when considering alloys for use in extreme corrosive environments.

Corrosion is an electro-chemical process that occurs between the surface of the material and the environment it is in contact with. For steel, it is essentially a process of oxidation and generally results in rusting on the surface. Corrosion can have various effects on the aesthetic and integrity of the structure depending on the extent of the process. Common types of corrosion found in the metal industry are uniform corrosion, pitting corrosion, galvanic corrosion, crevice corrosion, intergranular corrosion, dealloying and environmentally induced cracking such as hydrogen-induced cracking (HIC), stress-corrosion cracking (SCC) and corrosion fatigue. More information about specific case study on corrosion can be found in our technical resources.
