Duplex Steel S32205 Fasteners are crafted from a well-balanced duplex stainless steel alloy, featuring around 21–23% chromium, 4.5–6.5% nickel, 2.5–3.5% molybdenum, and nitrogen, with the rest being iron and trace elements. This unique dual-phase (austenitic-ferritic) structure grants them impressive tensile strength (approximately 655 MPa) and yield strength (around 450 MPa), along with good elongation and toughness. The material is known for its outstanding resistance to corrosion, stress corrosion cracking, and fatigue, often outperforming many traditional stainless steels in harsh environments.
