Duplex Steel S32205 coil is a top-notch alloy that brings together the best features of both austenitic and ferritic stainless steels. It boasts impressive corrosion resistance, particularly in harsh environments like those with chlorides and acids, while also delivering remarkable mechanical strength and durability. Thanks to its unique dual-phase microstructure, it offers exceptional toughness, high yield strength, and great resistance to stress corrosion cracking. This makes these coils a go-to choice in industries that require both strength and resilience against tough chemical and marine conditions, such as chemical processing, desalination, and offshore operations.
Typically, Duplex Steel S32205 coil is made up of about 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen, which boosts its resistance to pitting and crevice corrosion. With a tensile strength of around 620 MPa and a yield strength close to 450 MPa, it provides nearly double the strength of standard austenitic stainless steels. Plus, it maintains good ductility and toughness even in freezing temperatures, ensuring it performs reliably in challenging situations.
