Abstract The effect of sulfur contents on fracture toughness of railway wheel steels for high speed train was investigated. The results show that, with the same production process, sulfur content increase to some extent in wheel steels resulted in a great improvement in fracture toughness. The analysis of non–metallic inclusions revealed that, in the steel with sulfur content of 0.001%, a large amount of Al₂O₃ and complex Al₂O₃+(Ca,Mg)O inclusions were found, while MnS inclusions were rarely observed. When S content was increased from 0.001% to 0.006%, the type and morphology of inclusions were changed, MnS inclusions with core of Al₂O₃ were often observed and naked oxide inclusions were seldom found. This investigation shows that the fracture toughness improvement were closely associated with the type and morphology of inclusions due to sulfur content variation. The calculation showed that, with a cover of ductile MnS, stress concentration around complex inclusions decreased, which contribute to toughness improvement.

Key words: railway wheel steels fracture toughness inclusions tessellated stress
