Properties of Ductile Iron

To create different grades of ductile iron, one must control the matrix structure around the graphite during the casting process or through subsequent heat treatment. The minor compositional differences between the different grades of ductile iron exist in order to create the desired matrix (microstructures).

Ductile iron can be considered as steel with graphite spheroids dispersed throughout its matrix. The qualities of the metallic matrix in which the graphite spheroids are suspended have a significant effect on ductile iron’s properties, but the graphite spheroids themselves do not.


There are several matrices found within ductile iron, the most common being

1. Ferrite – a pure, ductile, flexible iron with little strength. This matrix has poor wear resistance, but high impact resistance and good machinability.

2. Pearlite – a mechanical mixture of ferrite and iron carbide (Fe3C). It is relatively hard, with moderate ductility. It has high strength, good wear resistance, moderate impact resistance, and good machinability.

3. Pearlite/Ferrite – a structure consisting of a mixture pearlite and ferrite, and the most common matrix for commercial grades of ductile iron.
