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
Cost fix Lengths More Cheaper
Application:
Producing camshaft
Delivery Condition:
+C No heat treatment after the final cold drawing process
+N After the final cold drawing operation the tubes are normalized in a controlled atmosphere
