Duplex and super duplex stainless steels combine roughly twice the yield strength of austenitic grades with far better resistance to chloride stress corrosion cracking, which often allows thinner sections at lower total cost.
Key features
- 2205 duplex for chloride-bearing effluent and moderate temperature service.
- 2507 super duplex where chloride and temperature are both high.
- Controlled welding procedures to hold the ferrite-austenite balance.
