The Duplex Steel S32205 fasteners are made up of about 22% chromium, 5–6% nickel, 3% molybdenum, along with trace amounts of nitrogen and manganese, creating a balanced duplex microstructure of austenite and ferrite. This distinctive composition results in remarkable mechanical properties, boasting tensile strength of up to 800 MPa, yield strength around 550 MPa, and hardness ranging from 25 to 30 HRC. The alloy is known for its excellent resistance to corrosion and stress corrosion cracking, especially in chloride environments, while also maintaining good toughness and ductility across a wide temperature range, making it perfect for critical fastening applications.
