Statistical study to determine the effect of carbon, silicon, nickel and other alloying elements on the mechanical properties of as-cast ferritic ductile irons

Further, that this finding applies to high silicon cast irons which are so prone to chunky graphite formation suggests that even a low level of antimony, as the 39 ppm added here,

A minimum limit of 18% in elongation has been adopted to optimise the mechanical properties of the prepared cast irons. On the other hand, a minimum silicon content of 3?00 wt-%

This discussion is mainly intended to find out if chunky graphite has any effect on room temperature tensile properties of high silicon spheroidal graphite cast
