英文摘要	The failure shaft for light hydrocarbon pump was analyzed through metallographica test. The fracture appearance was examined through 3-D stereoscopic digital camera and the scanning electron microscope (SEM). The results showed that the chemical composition of the shaft was fit to the requirement of structural steel. There was sulfide inclusion distributed among the white stripe phases. The figure of phases was striation, and the direction of striation was along the direction of the axis that was the machining direction when the shaft was fabricated. The fatigue fracture was the facture characteristic because there was fatigue striation on the fracture surface. The sulfide inclusion and segregation was the main reason of the fracture.
