The effectiveness of secondary inoculation of cast iron, performed using four various inoculants, i.e. Foundry Grade, Superseed 75, Superseed Extra and Inoculin 900, has been determined in the work. The inoculants have been introduced into the cast iron initially modified with FeSi75. Structural examination of the treated alloy has revealed that the cast iron chilling tendency is reduced to the greatest degree by Foundry Grade and Superseed Extra. The most significant structure refining (assessed by the number of eutectic grains per unit area) has been obtained for Superseed Extra used as an inoculant. Also the achieved tensile strength has the largest value for this case (about 350 MPa), while for other cases it has ranged from 290 MPa to 310 MPa.
