What is steel?
What are some of those properties?
Well, manganese, for example, is often added to increase the hardenability of the steel, while phosphorus can be used to improve the machinability. Sulfur, on the other hand, can negatively affect the toughness of the steel, so it is sometimes limited in certain applications. Silicon is often added to deoxidize the steel and improve its strength.
