Spheroidal graphite is obtained by spheroidizing inoculation treatment, which effectively improves the mechanical properties of cast iron, especially the plasticity toughness, so as to obtain higher strength than carbon steel. High quality EPC casting is a kind of high strength cast iron material developed in 1950s. Its comprehensive properties are close to that of steel. Based on its excellent properties, it has been successfully used to cast some parts with complex stress, high strength, toughness wear resistance. Nodular cast iron has developed rapidly into a widely used cast iron material next to grey cast iron. The so-called "replacing steel with iron" mainly refers to high-quality EPC Castings.

performance

Ductile iron castings have been applied in almost all major industrial sectors, which require high strength, plasticity, toughness, wear resistance, severe thermal mechanical impact resistance, high low temperature resistance, corrosion resistance dimensional stability. In order to meet these changes of service conditions, there are many brands of nodular cast iron, which provide a wide range of mechanical properties kiss physical properties.

For example, the majority of ductile iron castings specified by ISO 1501083 are mainly produced in non alloy state.
