| | Classification of Cast Iron |
 | | Because of the higher carbon content, the structure of cast iron, as opposed to that of steel, exhibits a rich carbon phase. |
 | | Therefore, the basic scope of the metallurgical processing of cast iron is to manipulate the type, amount, and morphology of the eutectic in order to achieve the desired mechanical properties. |
 | | Special cast irons differ from the common cast irons mainly in the higher content of alloying elements (>3%), which promote microstructures having special properties for elevated-temperature applications, corrosion resistance, and wear resistance. |
