How Chemistry Determines Machinability- Manganese Sulfides
Manganese sulfides are the reason that we can get improved surface finishes and higher surface footages with reduced flank wear from 11XX and 12XX series steels.

Seams are longitudinal voids opening radially from the bar section in a very straight line without the presence of deformed material adjacent. They are most frequently encountered of all imperfections/ defects due to so many possible causes.
Slivers are loose or torn segments of steel that have been rolled into the surface of the bar. they are often confused with laps, scabs, and mill shearing.
Cold Work, Thermal Treatments, and Chemical Composition are three major determinants of the machinability of steel.
