2.4602
Business Unit Manager Medical, Aerospace, Industry
Alloy 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
