Advantages of Ductile Iron

There are several advantages that ductile iron provides designers:

1. Ductile iron can be easily cast and machined.

2. It has an excellent strength to weight ratio.

3. Ductile iron can be made for a much lower cost than steel.

4. It has superior castability and machinability.

5. Ductile iron provides a designer with an exceptional combination of toughness, low cost manufacturing, and reliability.

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.

Ductile Iron Applications

Ductile iron has greater strength and ductility then gray iron. Those properties allow it to be used effectively in a wide variety of industrial

applications, including pipe, automotive components, wheels, gear boxes, pump housings, machine frames for the wind-power industry, and many

more.
