Black finish and hot dip galvanized
Excellent corrosion resistance
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).
Cold finished and stress-relieved
Heat treatment is applied following the last cold forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree.
The last cold forming process is followed by annealing in a controlled atmosphere.
The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.
