Hastelloy C-22 Alloy Sheet

ASTM/ASME N06022 Nickel sheet

EN2.4602 Nickel Alloy Plate

Hastelloy C22 is a Ni-Cr-Mo alloy containing W and extremely low carbon and Si contents.

  • outstanding resistance to a wide range of corrosive media, under oxidizing and reducing conditions
  • excellent resistance to pitting, crevice corrosion, and stress-corrosion cracking.

Density: 8.69

Corrosion resistance

The chemical composition of Hastelloy C22 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. Hastelloy C22 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 C22, 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 Hastelloy C22 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
