Steel often contains different alloying elements depending on its use

Ferritic and martensitic stainless steels are represented by 400 series numbers.

Steel is a general term for iron-carbon alloys with carbon content and mass percentage between 0.02% and 2.11%. The chemical composition of steel can vary greatly. Steel containing a small amount of manganese, phosphorus, silicon, sulfur and other elements with carbon content less than 1.7% is called carbon steel [5]. In practice, steel often contains different alloying elements, such as manganese
