The manganese content in carbon steels is often increased for the purpose of increasing depth of hardening and improving strength and toughness. Carbon steels containing over 1.2% up to approximately 1.8% manganese are referred to as carbon-manganese steels. Typical examples of this type of steel are AS3679 grade 300 and AS1442/1320.
