Characteristic properties
Successful fabrication in duplex steels require full awareness to their different properties compared to austenitic stainless steel
Welding
- Weldability of duplex is good
- Most welding methods can be used
- Welding characteristic deviates from austenitic steel
- Welding personnel must be informed and qualified according to the demands of the application
Cold forming
Higher strength of duplex steels:
- Greater working forces and spring-back during forming
- Somewhat lower ductility (fracture elongation) – avoid sharp bend radie and more demanding forming techniques
Machining
- Duplex steels generally more difficult to machine
- LDX 2101® has excellent machinability
