The **Super Duplex Steel S32760 Fasteners** are made up of chromium (24–26%), nickel (6–8%), molybdenum (3–4%), tungsten (0.5–1%), and nitrogen (0.2–0.3%), with iron making up the rest. This distinctive duplex microstructure, combining austenite and ferrite, grants them excellent mechanical strength and outstanding corrosion resistance. These fasteners boast a tensile strength of around 800 MPa and a yield strength of about 550 MPa, providing remarkable toughness and resistance to fatigue. They effectively resist pitting, crevice corrosion, and stress cracking induced by chlorides, maintaining their stability even under high temperatures and pressures.
