The various heat treatments of ductile cast iron involve heating and cooling a casting within specific temperature ranges for specific durations of time.

Over the decades, many industries have found uses for ductile cast iron, as its desirable mechanical properties qualify it for a host of engineering applications.

Ductile cast iron's unique mechanical properties are determined largely by spheroidal graphite nodules and their interplay within iron matrices on a microscopic level.

The principle difference in ductile iron vs. cast iron is its nodular graphite microstructure, which lends itself to several unique physical properties.

Invented in 1943, ductile iron improves upon other forms of cast iron by virtue of its spheroidal graphite nodules, enhancing yield strength, tensile strength, and elongation.

Production lead times in the foundry industry can be influenced by any number of internal or external factors relating to the complexity of the job, the capacity of the facility, the timing of the order, and the availability of labor.
