Super Duplex S32760
Description
Super duplex S32760 delivers high mechanical strength, excellent corrosion resistance, and reliable performance in the harshest conditions. Its balanced microstructure provides a PREN of 40 or more, making it a go-to material for seawater cooling, pulp and paper plants, and desalination systems. With a yield strength up to 600 MPa and solid ductility, S32760 is ideal for applications where strength and corrosion protection can’t be compromised.
Application：
- Oil and gas production environments
- Marine environments
- Chemical plants
- Seawater desalination plants
- Pressure vessel applications
- Sour service
