Abstract
The failure of a helical compression spring employed in coke oven batteries was analysed. Microstructural analysis and hardness measurements did not show any degradation of the spring material. Surface corrosion product was analysed by XRD and SEM–EDS. Sulphur and chlorine bearing compounds were detected. Macrofractography of the fracture surface revealed beach marks, indicating fatigue as the mode of fracture and surface pits. It was established that the spring failed due to corrosion fatigue.
