Washers made of Duplex Steel S32205 consist principally of 22 to 23% chromium, 4.5 to 6.5% nickel, 3 to 3.5% molybdenum, and 0.14 to 0.20% nitrogen, as well as balanced levels of manganese, silicon, and iron. The duplex microstructure of Duplex Steel S32205 provides the advantage of increased resistance against pitting, crevice corrosion, and chloride stress corrosion. The tensile strength of the washers made of duplex steel S32205 typically ranges from 620 to 700 MPa, and the yield strength is between 450 and 500 MPa. The hardness is approximately 290 HB with an elongation of approximately 25%. As a result, duplex steel S32205 provides excellent durability and toughness while providing dependable performance in many industrial applications requiring high levels of performance.
