Manganese steel has no equal in it ability to work-harden. Although it is normally reported that a maximum hardness of about 550 BHN is obtainable, typical maximum hardness on worn castings is in the 400–450 BHN range. It is generally believed that manganese steel has poor abrasion resistance unless it has been work-hardened.
