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.
