Ductile iron is made by the treatment of molten iron with no-dulizing (spheroidizing) material. During this treatment, gra-phite changes from flakes to nodules or spheres. The treatment process is a key operation in the production of ductile iron that ensures a predetermined microstructure, and mechanical and engineering properties of castings.

Therefore the solidified pig iron is also called grey pig iron. The fracture surface of a metastable solidified pig iron, on the other hand, has a whitish shine and is therefore also called white pig iron. Figure: Grey and white pig iron. With stable solidification, carbon precipitates in pure form as graphite (grey pig iron)!
