UNS S32950 is a nitrogen-enhanced duplex stainless steel with high strength and good resistance to stress corrosion cracking. Super duplex stainless steel combines a balanced austenitic-ferritic microstructure with high chromium, molybdenum and nitrogen content, giving very high strength and excellent resistance to pitting, crevice corrosion and chloride stress corrosion cracking.
What you can source
- Seamless Pipes — The go-to choice for high-pressure and high-temperature lines.
- ERW Pipes — Economical welded pipe for utility and process piping.
- Welded / EFW Pipes — Fusion-welded construction for large-diameter runs.
- Tubes — Round, square and rectangular tubes, plus U-bends for heat exchangers.
Key properties
- High Strength — Roughly twice the yield strength of standard austenitic stainless steels.
- Chloride Resistance — Excellent resistance to pitting and crevice corrosion in seawater and brine.
- Stress Corrosion Resistance — Strong resistance to chloride stress corrosion cracking.
- Weight Saving — Higher strength allows lighter designs in suitable applications.
