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)
