    • What Is the Composition of Cast Iron? Reference

      This type of cast iron is called grey cast iron, and its main characteristic is the grey colored carbon flakes in its composition. To produce cast iron, iron ore is deoxidized in a blast furnace. When the ore is melted, it is poured into molds.
