Duplex and Super Duplex UNS S32760 Threaded Rods

Duplex and Super Duplex UNS S32760 Threaded Rods are continuously threaded bars manufactured from Super Duplex Stainless Steel (UNS S32760, F55). Zeron Fasteners specializes in supplying these highly robust rods, which are commonly cut to length for use as stud bolts or anchors in critical, high-load industrial applications. The product is characterized by its high mechanical strength and outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC) in aggressive chloride and acidic environments. The Super Duplex material ensures that the resulting fasteners provide the highest integrity in the most demanding industrial environments, surpassing standard stainless steel grades. The primary application of these UNS S32760 Threaded Rods is in tension-critical systems within desalination plants, offshore structural anchoring, large flange assemblies for pressure vessels, and chemical processing equipment.
