ASTM A519 Precision Seamless Steel Tube
Torich International Limited is a professional manufacturer and exporter of steel pipes materials.
Our main products are precision seamless steel tube,carbon seamless steel tube,The material we usually use for producing precision seamless steel tube is10#,20#,1010,1020,1026,ST37,ST44,E235,E215,E355.
Delivery condition:
| Designation | Symbol | Description |
| Cold finished (hard) | BK(+C) |
Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation |
| Cold finished (Soft) | BKW
(+LC) |
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(+SR) |
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(+A) | The last Cold forming process is followed by annealing in a controlled atmosphere. |
| Normalized | NBK(+N) | The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere. |
