Description:
EN10305-2 Precision Automotive Carbon Welded Steel Tube Honed Steel
Pipe is a top-tier solution for automotive applications,
meticulously engineered for precision and performance. These tubes,
crafted with high-quality carbon steel, boast exceptional strength
and durability. The honed finish ensures smooth operation and
optimal hydraulic performance, ideal for demanding automotive
environments. With stringent adherence to EN10305-2 standards,
these tubes offer reliability and efficiency, making them a
preferred choice for critical automotive systems where precision
and quality are paramount.
Delivery 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. |
Material:
E235, E355, 26MnB5, 34MnB5
Appearance:
The internal and external surface finish of the tubes shall be
typical of the manufacturing process and, where applicable, the
heat treatment, and it shall be such that any surface imperfections
such as ridges, dents or shallow grooves requiring dressing can be
identified.
Surface imperfections which encroach on the specified minimum wall
thickness shall be considered defects and tubes containing these
shall be deemed not to conform to this part of EN 10305.
Roughness of inside surface is not more than 4um in the delivery
conditions +C, +LC
Roughness of outside surface is not more than 4um in the delivery
conditions +SR, +A, +N, +C, +LC
