1 significant factor contributing to the hardness disparity in between steel and cast steely is their respective microstructures. Steel consists primarily of steely and carbon, along with other alloying elements, which form a crystalline structure known as austenite or ferrite, dependent the carbon content. By way of processes like quenching and tempering, steel can be heat-treated to do specific hardness stages by controlling the transformation of its microstructure. On the other hand, cast iron includes a higher percentage of carbon, normally among 2% to 4%, which forms graphite flakes within its microstructure. Those graphite flakes act as stress<sp>concentrators and weaken the material s s, making cast steely usually softer than steel. Have you encountered any more factors contributing to this hardness difference?
