EN10305-2 E215 OD10 Automotive Welded Steel Tube , High Precision Steel Tube

Cold Drawn Precision Welded Steel Tube Round Shape For Automotive

Description:

Our cold drawn precision welded steel tubes are meticulously crafted to meet the straight requirements of the automotive industry. With advanced manufacturing techniques, we ensure exceptional precision, dimensional accuracy, and durability. These tubes play a vital role in enhancing the performance and reliability of automotive systems, setting new standards in quality and engineering excellence.

Typical Specification:

Delivery Condition:

1) +C No heat treatment after the final cold drawig 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:

Top class of welding line: SG/76 Enhanced High-precise High Frequency Welding Tube Production Line. The tube is of small outer diameter (D) and thick wall thickness (t): t/D≥0.2, and high size precision.

Production Equipment:
