Iron castings are used to a significant extent in the energy sector. The applications range from gray iron for large valves through white cast iron for grinding media to ductile iron for piping. One major problem, which is well-known to metallurgists, but not too commonly considered by designers, is the metastability anomaly of cast iron. This results in significant changes in the mechanical properties of the product, which may have serious consequences on the service life of the product. For a given composition, variations in the microstructure are caused by the thermal conditions under which the casting solidifies. In this paper, the influence of the thermal conditions will be discussed with several illustrative principles. Knowledge of these factors would better equip the designer to recognize problems in advance and have effective dialogue with the foundryman in producing components where undesirable effects are avoided.
