What is ductile iron?

Ductile iron is more impact and fatigue resistant than gray iron due to the spheres of graphite that form with added magnesium. The science and strength of ductile iron From a microstructure standpoint, the primary difference between gray and ductile iron is the shape of the graphite. Gray irons have flake graphite, whereas ductile iron…

Metalcasting: All about iron

Engineering Manager RJ Hawkins explores the main differences and applications between gray and ductile iron. From a microstructure standpoint, the primary difference is the shape of the graphite. Gray irons have flake graphite, where ductile iron has a nodular or spherical shape. This graphite shape is what drives the basic difference in each from a…
