About Duplex Steel
- Twice design strength of austenitic and ferritic stainless steels
- Wide range of corrosion resistance to match application
- Good toughness down to minus 80 deg C but not genuine cryogenic applications
- Particular resistance to stress corrosion cracking
- Weldable with care in thick sections
- More difficult to form and machine than austenitics
- Restricted to 300 deg C maximum
