Duplex and Super Duplex UNS S32205 Threaded Rods

Duplex and Super Duplex UNS S32205 Threaded Rods are continuously threaded bars manufactured from the enhanced Duplex Stainless Steel UNS S32205 (Alloy 2205). These rods function as customizable stud bolts or tie rods, providing exceptional tensile strength and superior resistance to corrosion, particularly chloride-induced stress corrosion cracking and pitting. The enhanced composition (compared to S31803) ensures reliable performance in critical high-load, high-corrosion applications. Zeron Fastners supplies these rods for various uses, including securing structural elements, machinery anchoring, and large-scale tensioning applications in offshore, marine, petrochemical, and power generation facilities.
