The contribution deals with comparing of microstructure, mechanical properties and micromechanisms of failure of synthetic nodular cast irons with graded amount of steel scrap in a charge. Chemical composition of individual meltages was regulated alternatively by ferrosilicon (FeSi) and carburizer or metallurgical silicon carbide (SiC). The paper shows that SiC additive positively influences the microstructure, mechanical properties and micromechanisms of failure of nodular cast iron, especially in the meltages with higher ratio of steel scrap in the charge. Moreover, production of synthetic nodular cast irons with SiC additive is economically advantageous.
