Killed steel is a type of steel that has been treated with deoxidizers, such as aluminum or silicon, to remove oxygen and prevent the formation of gas bubbles during solidification. This results in a more uniform and high-quality material. Rimmed steel, on the other hand, is produced without such deoxidizers, allowing some gas to remain, which creates a rim of purer steel around a more impure core. Consequently, killed steel generally has better mechanical properties and is used for more demanding applications compared to rimmed steel.
