Duplex and Super Duplex UNS S32205 Springs

Duplex and Super Duplex UNS S32205 Springs are resilient components designed to store and release mechanical energy. Manufactured from the high-performance Duplex Stainless Steel UNS S32205 (Alloy 2205), these springs exhibit outstanding fatigue strength and high elastic limits. The duplex structure provides superior resistance to stress corrosion cracking and localized corrosion compared to standard stainless steels, making them ideal for dynamic applications in highly corrosive or high-stress environments. Zeron Fastners custom-manufactures these springs in various forms, including compression, tension (extension), and torsion springs, for use in valves, actuators, and mechanical seals within the chemical, oil and gas, and marine sectors.
