AB  - The aim of this paper was to determine the causes of screws failures in compressor valves, obtained from petroleum industry. The analysed screws were in exploitation and deposition coated. Before the fracture analysis, control calculation of screws is done in order to determine, if the screws are properly dimensioned. After visual and radiographic examination, their chemical composition and structure were analysed. Detail fractography was performed on fractured surfaces to try to obtain an impression about screws failure mechanism. Qualitative analysis of deposit was employed in order to confirm if there was any possible influence of surroundings during their failure in terms of corrosion-assisted cracking. The macrofractography of originally broken surfaces shows a rough and complex topography of fracture surfaces indicating to a possibility that screws failure has been a result of complex loading conditions. Presence of sulfur containing particles on the fracture surfaces of broken screws and in deposit reveals a possibility that failure was environmentally-assisted.
