Abstract

Vermicular cast iron of high machinability and free from microporosities, comprising classes between 350 and 500 MEGA PASCAL of ultimate tensile strength, presenting a bigger amount of graphite by volume of vermicular cast iron, this increase in the amount of graphite obtained with additional nodules in the microstructure so that the percentage of those nodules is also increased in relation to the volume of vermicular cast iron.
