Ferro silicomanganese: Ferro silicomanganese is a ferroalloy that contains iron, silicon, and manganese as the main elements. It is used as a ladle addition during steelmaking to provide silicon and manganese, which act as deoxidizers and alloying elements. Ferro silicomanganese has a lower carbon content than high-carbon ferromanganese, and it can improve the properties of steel such as strength, toughness, hardness, and abrasion resistance.
