Our Duplex Steel Washers are made from dual-phase stainless steel, specifically grades UNS S31803 and S32205, which cleverly combine the advantages of both ferritic and austenitic microstructures. They boast impressive tensile strength (typically around 620–880 MPa) and superior yield strength, along with remarkable resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking. These washers maintain their structural integrity even under high-pressure and high-temperature conditions. Plus, duplex steel is known for its good weldability and fatigue resistance, making it an excellent choice for washers in high-load and corrosive settings.
