Hastelloy C276 Springs

Hastelloy C276 Springs are mechanical fasteners designed to store energy and resist a compressive, tensile, or torsional force, returning to their original shape when the force is removed. In environments where both mechanical reliability and resistance to degradation are paramount, standard materials are insufficient. Made from **Hastelloy C276**, a superior nickel-molybdenum-chromium alloy, these springs offer exceptional corrosion resistance to a wide variety of severe media, including wet chlorine gas, hypochlorite, and strong oxidizing salts. This makes them critical components in valves, seals, pumps, and specialized instrumentation within the chemical processing, pollution control, and industrial furnace sectors. Zeron Fasteners manufactures and supplies precise, high-integrity nickel alloy Springs to ensure reliable performance under extreme stress and corrosion.
