Product Description

EN10305-2 Precision Automotive Carbon Welded Steel Tube Honed Steel Pipe

 

 

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

Tube OD: 4-30mm, WT: 0.5-10mm

Surface treatment in delivery: Oiled, black phosphated, zinc coated

Application: automotive, vehicle, general engineering industries.

 

Each piece of tube is high pressure flushed for high cleanness
