Application:
High Precision Cold Rolled Seamless Steel Tube is used in automotive industry, and in the occasion where the high accuracy, brightness, cleanness of the tube are required.
Sizes Range:
OD:8mm-280mm, WT:1mm-15mm
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 drawn seamless steel tube is produced by drawing raw hot rolled steel tube through a die and over a mandrel plug. 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.
Surface treatment: Oiled, black painted, hot dipped galvanized or phosphate coating as required.
Both ends of each crate will indicate the order no., heat no., dimensions, weight and bundles or as requested.
