Duplex Stainless Steel Coil S31803/S32205
Introduction:
The S31803 and S32205 duplex stainless steel coils are high-performance materials designed for industrial, chemical, petrochemical, and offshore applications where superior corrosion resistance and high strength are critical. Featuring a duplex microstructure combining ferritic and austenitic phases, these coils provide excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, while maintaining high tensile strength and durability. The continuous coil form enables efficient fabrication, cutting, and shaping, making it ideal for pipelines, tanks, heat exchangers, and structural applications. The pickled and passivated surface ensures enhanced corrosion resistance and a smooth, cleanable finish, suitable for industrial and chemical process environments.
