Duplex UNS S32205 is a stainless steel grade known for its excellent combination of properties, including high strength and corrosion resistance. It belongs to the duplex family of stainless steels, characterized by a dual-phase microstructure of austenite and ferrite. This grade offers superior resistance to chloride stress corrosion cracking, making it suitable for use in aggressive environments such as marine applications, chemical processing plants, and oil and gas industries. Duplex UNS S32205 is also valued for its good weldability and formability, making it versatile for various structural and industrial applications where durability and performance under challenging conditions are essential.

Manufacturing Duplex UNS S32205 involves precise alloying of iron, chromium, nickel, and other elements in an electric arc furnace, followed by refining and casting into billets. These billets are hot worked and shaped through forging or extrusion into fittings such as elbows, tees, and end caps. Controlled cooling processes maintain the dual-phase microstructure of austenite and ferrite, crucial for its corrosion resistance and mechanical strength.

Further processing includes heat treatment to optimize properties and machining to achieve precise dimensions. Stringent quality checks ensure compliance with industry standards, ensuring Duplex UNS S32205 fittings deliver reliability and durability in demanding applications like marine environments, chemical processing, and oil and gas industries.

Inspection of Duplex 2205 buttweld fittings involves visual checks for surface defects, followed by dimensional verification using precise instruments. Non-destructive testing methods like ultrasonic testing and dye penetrant testing detect internal flaws, while chemical analysis ensures alloy composition meets specifications.
