Description |
| Cold finished (hard) |
BK |
Tubes do not undergo heat treatment following final cold forming, providing high resistance to deformation |
| Cold finished (soft) |
BKW |
Final heat treatment followed by cold drawing with limited deformation, allowing certain cold forming |
| Cold finished and stress-relieved |
BKS |
Heat treatment applied after last cold forming process, enabling forming and machining |
| Annealed |
GBK |
Last cold forming process followed by annealing in controlled atmosphere |
| Normalized |
NBK |
Last cold forming process followed by annealing above upper transformation point in controlled atmosphere |
