Cold Drawn Tubes

GERNERAL FEATURES

These products are Manufactured by cold drawing of seamless and welded fully killed steel tubes.This Particular process assures a high dimensionals precision,while different kind of following heat treatments are used to reach different levels in mechanical properties.Types

The different kinds of cold drawn tubes ready on stock cover a wide range of applications :

• COLD DRAWN SEAMLESS AND WELDED TUBES SUITABLE FOR HONING

• COLD DRAWN SEAMLESS AND WELDED TUBES INSIDE H8

• COLD DRAWN SEAMLESS TUBES FOR SHAFTS

• WELDED SMOOTH BORE CYLINDER TUBES INSIDE H9 OR H10.

• COLD DRAWN SEAMLESS TUBES FOR HYDRAULIC AND PNEUMATIC POWER SYSTEMS.

  STEELGRADES AND DELIVERY CONDITIONS

   

   

  1.COLD DRAWN/HARD 

  ( Cacc.EN10305/BK acc.DIN2391)

  No heat treatment after final cold drawing.

  2.COLD DRAWN/SOFT

   

  ( LC acc.EN10305/BKWacc.DIN2391)

  The final heat treatment is followed by a suitable drawing pass

  (limited reduction of area)

   

   

  3.STRESS RELIEVED

  ( SRacc.EN10305/BK Sacc.DIN2391

  After the final cold drawing process,tubes are stress relieved in controlled atomosphere in order to reduce work hardening due to the cold forming process.

   

  4.ANNEALED(Aacc.EN10305/GBKacc.DIN2391)After final cold drawing process,tubes are annealed in controlled atomosphere.
