E355 EN10305-2 WT7 Stress Relieved Welded Carbon Steel Pipe Cutting To Specified Length

EN10305-2 Welded Cold Drawn Carbon Steel Tube For Precision Applications

Description:

EN10305-2 welded cold drawn carbon steel tube for precision applications is manufactured through a rigorous process that ensures high strength, precise dimensions, and excellent surface finish. It adheres to strict quality standards for reliability in critical applications.

Delivery Conditions:

+C Hard. No final treatment after final cold drawing.

+LC Soft. Final heat treatment is followed by a suitable drawing pass (limited reduction of area).

+SR Stress Relieved. After final cold drawing, the tubes are stress relieved in a controlled atmosphere.

+A Annealed. After final cold drawing, the tubes are annealed in a controlled atmosphere.

+N Normalized. After final cold drawing, the tubes are normalized in a controlled atmosphere.

Process:

The cold rolled welded tube is produced by drawing ERW (electric resistance welded tube).During this process the sizing (wall thickness, inside and outside diameter), as well as weld integrity and surface finish is closely controlled to produce tube of the required size and mechanical property characteristics.

Tube Finishing Options:

Our tubes can be additionally treated to achieve the exact finishes and ends needed by customers. These are some of the additional operations that can be performed on our tube:Drawing, Heat treatment, Bulging, Swaging, Cutting, Deburring, Vibro cleaning, Threading,De-rusting, Chamfering, Washing.
