Abstract
A ductile iron composition (201) including, by weight: about 3.1 % to about 3.6% C; about 3.5% to about 4.0% Si; about 0.035% to about 0.050% Mg; about 0.001% to about 0.004% Ce; up to about 0.005% Sb; about 0.008% to about 0.016% S; up to about 0.04% P; up to about 0.3% Mn; and balance iron and incidental impurities; The ductile iron composition (201) includes a ratio of Sb/Ce greater than or equal to about 1.25, has a ferritic microstructure and graphite nodules, and greater than about 65% of the graphite nodules having a highly spherical geometry. A method and apparatus (100) for forming a ductile iron composition (201) are also disclosed.
