Abstract: The feasibility of SiC inoculation for low carbon steel was studied in this work. Five heats of low carbon steel with different percentage of silicon carbide inoculants have been compared with the reference steel in terms of microstructure, tensile properties, and wear abrasion resistance. The optical observations using optical and scanning electron microscope declare that the weight percentage of SiC inoculants has a significant effect on the pearlite fractions increment, as well as its morphology. The excellent response of the enhancement in the pearlitic structure is observed by tensile test. The impact toughness of inoculated steel approaches 250% more than non-inoculated steel. In the same way, the wear abrasion resistance is improved by nanoinoculation, especially at heavy load conditions.
