Super Duplex Steel washers produced from S32760 alloy have a balanced duplex microstructure consisting of around 25-26% chromium, 3.5-4% molybdenum, 6-7% nickel, and nitrogen. This composition ensures superior resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in chloride-rich and aggressive chemical conditions. Mechanically, the S32760 washers demonstrate high tensile strength of 830-860 MPa and yield strength of 550-620 MPa, which makes them much stronger than conventional austenitic stainless steels. They are also tougher and resistant to fatigue, which qualifies them for important sealing and load-carrying applications.
