Remarks:

Cold Finished (Hard):  Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation

Cold Finished (Soft):  The final heat treatment is followed by cold drawing involving limited deformation. Appropriate further processing allows a certain degree of cold forming (e.g. bending, expanding)
