ASTM A106 305L High Precision Smooth Surface Cold Rolled Seamless Steel Pipe For Mechanical Structure
Product Description:
High precision cold-drawn steel pipe is a new type of steel pipe, its main characteristic is high precision. Usually there are two production processes of two-high rolling mill and three-high rolling mill. The precision of cold-rolled seamless steel pipe produced by three-high rolling mill is higher, which can be controlled within a few wires, but the price is relatively higher.

Final supply conditions:
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. |
