Condition Details
Designation | Symbol | Description |
Cold finished (hard) | BK | Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation. |
Cold finished (soft) | BKW | 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 | BKS | 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. |
Annealed | GBK | The last cold forming process is followed by annealing in a controlled atmosphere. |
Normalized | NBK | The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere. |
Tests we apply to the tubes
1) Chemical Composition Analysis
2) Mechanical Properties (Tensile strength, Yield strength,, Elongation, Hardness)
3) Technological Test (Flattening test, Flaring Test, Bending Test, Hydraulic pressure test)
