Sulfur in steel increases machinability, but all free machining agents, such as sulfur, lead, calcium, etc., are in essence dirt, or elements taken directly from the earth. Such free machining elements improve the machinability but do not homogenize in the steel making process and can cause pockets, stringers or other faults that can affect some appliions.
