It's a great question. A major purpose for steel's hardness superiority lies in its microstructure. Steel generally has a crystalline structure composed of iron and carbon, with other alloying elements mixed in dependingon the distinct type of steel. This microstructure can be manipulated by way of temperature treatment method procedure processes like quenching and tempering to attain varying levels of hardness. In contrast, cast steely includes a higher concentration of carbon, which forms graphite flakes inside its structure. Those graphite flakes act as stress<sp>factors, generating cast iron commonly softer than steel. However there's more to it than only composition—what do you think?
