Alloy steels are steels with alloying elements other than iron and carbon. When various elements are added to these steels, they become stronger and harder than plain carbon steels. If the total amount of alloy additions accounts for less than 5%, the steel is regarded as a high alloy steel. If the total is above 5%, the steel is called as a low alloy steel.
