Duplex Steel washers are typically made from a balanced blend of austenitic and ferritic stainless steels with approximately 21-23% chromium, 4.5-6.5% nickel, 2.5-3.5% molybdenum, and 0.08-0.20% nitrogen, along with varying quantities of manganese, silicon, and iron. Their dual-phase structure provides increased strength and resistance to corrosion, particularly with regard to chloride stress corrosion cracking. Mechanically, Duplex Steel washers possess superior mechanical characteristics with a tensile strength of approximately 620 MPa, yield strength of approximately 450 MPa, hardness of approximately 290 HB, and elongation of approximately 25%, assuring durability and dependability in demanding conditions.
