Free cutting steels are steels with low machining cost due to chips broken when subjected to fast chipping process. Thanks to its easy machinability characteristics, these steels are defined as the most suitable for machining processes such as longitudinal and face turning, toothing, drilling, reaming operations that are performed in multi spindle and revolver turning lathes. These steels are used for manufacturing axles, bolts, screws, nuts, special duty shafts, connecting rods, small and medium forgings, cold upset wires and rods, solid turbine rotors, rotor and gear shaft, armature, key stock, forks and anchor bolts screw stock, spring clips, tubing, pipes, light weight rails, concrete reinforcing etc.
