Duplex and Super Duplex UNS S32760 Washers

Duplex and Super Duplex UNS S32760 Washers are essential load-distributing components manufactured from Super Duplex Stainless Steel (UNS S32760, F55). Zeron Fasteners specializes in supplying these highly durable washers, which are crucial for achieving reliable load distribution and preventing damage to the mating surfaces during the tightening of high-strength Super Duplex bolts. The product is characterized by its high strength and hardness, which complements the robust mechanical properties of Super Duplex bolting systems. UNS S32760 offers outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking in aggressive chloride and acidic environments. The primary application of these UNS S32760 Washers is in critical flange connections for high-pressure vessels, oil and gas pipelines, structural assemblies on marine platforms, and chemical plants, where the entire fastening assembly must withstand severe corrosion.
