Duplex Stainless Steel Sheet S31803

Duplex Stainless Steel Sheet S31803

Introduction:
The S31803 duplex stainless steel sheet is a high-performance industrial material designed for applications requiring superior corrosion resistance and high strength. With a duplex microstructure combining ferritic and austenitic phases, S31803 offers excellent resistance to chloride-induced stress corrosion, pitting, and crevice corrosion, while maintaining high tensile strength and durability. This makes it ideal for chemical processing, petrochemical plants, offshore structures, desalination, and industrial fabrication. Its pickled and passivated surface ensures a smooth and corrosion-resistant finish, suitable for both structural and process applications.
