C22 / 2.4602

Alloy C22 is very resistant to many corrosive media under oxidizing and reducing conditions. It is, for example, resistant to:

- Splitting, cracking and pitting corrosion

- Moist chlorine gas

- Chloride and hypochlorite ion attacks

- chlorine dioxide

- Solutions of oxidizing salts
