Ductile Cast Iron: Process, Composition, Differences and ...

Ductile iron casting refers to a process in which magnesium / cerium (as an alloy of magnesium / cerium) is added to cast iron. It reacts with the sulfur and oxygen in the molten iron and changes the way the graphite is formed. Ductile cast iron (also called as spheroidal graphite cast iron or nodular cast iron) has been widely used as a main industrial material in place of high-grade cast iron.
