Material Properties
Duplex 2205 stainless steel (UNS S31803/S32205) offers exceptional corrosion resistance combined with high strength. This nitrogen-enhanced grade provides superior performance compared to standard austenitic stainless steels.
Key Benefits
- High resistance to pitting and crevice corrosion
- Excellent performance in most caustic environments
- Superior weldability characteristics
- Enhanced strength-to-weight ratio
Note: Not recommended for use above 300°C (brittle precipitation) or below -50°C (ductile-to-brittle transition).
