ASTM A519 Cold finished Mild Steel Tubing , Thin Wall Alloy Steel Mechanical Tube with API
Product Description
This specification covers for several grades of carbon and alloy steel mechanical tubing, either hot-finished or cold-finished. The steel used in the mechanical tubing may be cast in ingots or may be strand cast. When steel of different grades is sequentially strand cast, identification of the resultant transition material is required.

Tube Designation:
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. |
