Nodular cast iron is a kind of high-strength cast iron material developed in the 1950s. Its comprehensive properties are close to that of steel. It is based on its excellent properties that nodular cast iron has been successfully used to cast some parts with complex stress, high strength, toughness and wear resistance requirements. Nodular cast iron has developed rapidly into a widely used cast iron material next to grey cast iron. The so-called "iron for steel" mainly refers to ductile iron.

Spheroidal graphite is obtained by spheroidizing and inoculation treatment, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, so as to obtain higher strength than carbon steel.
