Corrosion resistance

The chemical composition of Alloy 22 has been designed to give it outstanding corrosion resistance in as wide a range of media as possible, both oxidizing and reducing. The high chromiurn content of the alloy makes it particularly suitable for oxidizing conditions, including wet chlorine gas, hypochlorite solutions or oxidizing acids. It is remarkably resistant to localized attack by halide ions, even under severe conditions of low pH and high temperatures. It resists attack in media contaminated by oxidizing chlorides such as ferric chloride or cupric chloride. Alloy 22 is also resistant to many reducing media. As a result it can be used for equipment in polyvalent
chemical plant where widely varying conditions may be encountered. The very low carbon content of Alloy 22, together with its balanced composition, reduce the tendency to formation of grain-boundary precipitates in the heat-affected zone during welding, thus
making it suitable in the as-welded condition for many applications in the chemical process industry.

Applications

The versatile nature of Alloy 22 combined with its excellent mechanical properties mean that it can be used in a wide variety of applications, including:

  • organic syntheses
  • flue gas desulphurization
  • electrolytic galvanizing
  • plate heat exchangers
  • fine chemicals production
  • incineration plants
  • pharmaceutical intermediates
  • combustion-resistant alloy for high pressure oxygen applications
