Product Description

Cold Drawn Weld Steel Tube EN10305-2 (DIN2393) Automotive Part Camshaft Pipe

 

Manufacturing Process

Cold Drawn Weld Steel Tube is called as DOM, It 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.

 

Material E235,E355
OD 6-80mm
WT 0.5-10mm
Standard EN10305-2, DIN2393
Technique Cold Drawn

Deliver condition:
1) +C No heat treatment after the final cold drawing process
2) +LC After the final heat treatment there is a suitable drawing pass
3) +SR After the final cold drawing process there is a stress relieve heat treatment in a controlled atmosphere
4) +A After the final cold drawing process the tubes are annealed in a controlled atmosphere
5) +N After the final cold drawing operation the tubes are normalized in a controlled atmosphere

 

Advantage (compare with seamless cold drawn tube)

Better shape

Improved quality surface

Tight Excentricity and wall thickness tolerances (the eccentric

Tube more safety

Good toughness at low temperature

USA Market: 90% of the cylinder in the USA market are produced with welded tubes
