Duplex Steel S32205 Flanges is a widely used duplex stainless steel grade known for its excellent corrosion resistance and high strength. The alloy combines the desirable properties of both austenitic and ferritic stainless steels, making it suitable for a variety of applications, including the manufacture of flanges.
Composition and Properties: Duplex Steel S32205 consists of a dual-phase microstructure with approximately equal proportions of austenite and ferrite phases. This balanced composition contributes to its exceptional corrosion resistance and mechanical strength. The alloy typically contains elements such as chromium, molybdenum, nickel, and nitrogen, which enhance its overall performance.
Corrosion Resistance: One of the key attributes of Duplex Steel S32205 Flange is its resistance to various corrosive environments. The presence of chromium and molybdenum provides excellent resistance to localized corrosion, including pitting and crevice corrosion. This makes S32205 flanges suitable for use in challenging conditions such as chemical processing, marine environments, and offshore oil and gas applications.
