EN10305-2 26MnB5 WT6 Carbon Steel Tube, Welded Steel Tube For Vehicle Parts
Description:
EN10305-2 26MnB5 WT6 carbon steel tubes are specifically engineered for vehicle parts, offering superior strength and durability. These welded steel tubes are crafted from high-quality materials, ensuring excellent mechanical properties and resistance to wear. Their precise dimensions make them ideal for critical automotive applications, where reliability is paramount. Designed to withstand extreme conditions, these tubes provide enhanced performance and safety in vehicles. With a focus on quality and resilience, they are essential components for modern automotive engineering.
Main Date:
Material: 26MnB5
Other Aviliable Material: E155 E195 E235 E275
Outer Diameter Range: 10-50mm
Wall Thickness Range: 1.5-8mm
t/D ≥ 0.2(Normal: t/D=0.1)
Standard: En10305-2
Process: Cold Drawn, Cold Rolling
Application:
1.Auto and Motorcycle Parts(Fuel Injection Parts, Diesel Engine Parts, Shock Absorber,Gas Spring)
2.Exhaust Pipe for Generator
3.High Heels Steel Pipes
4.Bicycle Frame(Stnadard or Customize)
5.Hydraulic Pipe(Hydrocylinder Pipe)
6.Oxygen Lance Pipe
Production Method:
The cold drawn welded tube 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.

Delivery 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):
1.Better shape
2.Improved quality surface
3.Tight Excentricity and wall thickness tolerances (the eccentric
4.Tube more safety
5.Good toughness at low temperature
6.USA Market: 90% of the cylinder in the USA market are produced with welded tubes
7.Cost fix Lengths More Cheaper
Advantage of Our Company:
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.
