What Is the Composition of Cast Iron?

Cast iron breaks when it is loaded with significant pressure, although the carbon content in cast iron makes this metal good for casting 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.
