Duplex and Super Duplex UNS S32750 Washers

Zeron Fasteners specializes in supplying premium quality Duplex and Super Duplex UNS S32750 Washers. A washer is a critical component in a bolted assembly, primarily used to distribute the load of a threaded fastener, such as a nut or bolt head, reducing the risk of damage to the surface and preventing loosening. The Super Duplex S32750 material, with its high PREN value, provides outstanding resistance to stress corrosion cracking and pitting in aggressive, chloride-rich environments. These highly durable Duplex Washers are essential for demanding applications in chemical processing, oil and gas, and shipbuilding industries where reliable, high-integrity fastening is mandatory.
