Abstract：Oxide inclusions had great influence on the properties of die steel with high vanadium (PCDV). In this paper, stable oxide inclusions were drawn by electrolytic method. Qualitative analysis was processed based on Xray diffraction (XRD) and scanning electron microscope (SEM). The content of composition in oxide inclusions were tested by ICPAES, and the quantitative analysis was carried out based on it. The result indicated that Al2O3,silicate,MgAl2O4 and SiO2 were main oxide inclusions in PCDV. The content of Al2O3 was 9151% in all oxide inclusions. Inert gaspulse heating method was used to determine the oxygen content in this alloy. The extractive method of inclusions was verified by comparing the testing and calculative content of oxygen. Quantitative analysis showed that the content of oxide inclusions in PCDV was 0026 5%.
