The Properties and Effects of Manganese as an Alloying Element

Manganese has similar effects like carbon, and steel producers use both of these elements to achieve a material with preferred properties. Manganese is required for the hot rolling process of steel by combining it with sulfur and oxygen. Steels often include 0.30% manganese, but certain carbon steels can include up to 1.5% of manganese.
