ABSTRACT:
An iron base alloy having excellent machinability characterized in having a high sulfur content in the form of small, uniformly distributed particles of manganese sulfide in its microstructure. The alloy, produced by strand-casting techniques to form billets which are subsequently hot-worked into bars or other shapes, consists essentially of up to about 0.50 % carbon, 1.15 to 1.35 % manganese, at least 0.40 % sulfur, about 0.15 to 0.30 % silicon and the remainder substantially all iron with incidental impurities.
