The ladle treatment technique for molten Hadfield steel was utilized by using four groups of CaSi inoculants and Mg metal in order to exclude the most hard‐control conventional heat treatment process. The effect of ladle treatment on the morphology of Cementite networks, hardness, impact strength, and wear abrasion resistance were investigated. The SEM indicates that cementite is dispersed throughout the austenite matrix in a new eutectic. This eutectic grows on heterogeneous nuclei either SiO 2 or MgS. Impact strength of modified as cast Hadfield steel exceeds the as heat‐treated steel. The wear abrasion resistance of modified steel is 350% in excess of the conventional Hadfield steel.
