E235 EN10305-2 OD10 Auto Industry Thin Wall Steel Tubing Cold Drawing With ISO9001 Certification

EN10305-2 Welded Steel Tubes Precision Cold Drawn Steel Tubes for Auto Industry

Introduction

Precision cold drawn welded steel tubes are a key component in the auto industry, providing superior strength, durability and corrosion resistance. Our tubes are manufactured from high-quality steel alloys and undergo a precise cold drawing process to ensure precise dimensions and tolerances. With excellent welding quality, these tubes are ideal for use in auto parts like steering columns, brake lines and suspension components, offering a reliable and long-lasting solution for automotive applications.

The tubes are manufactured from electric welded pre-tubes by cold drawing or other suitable processes.

The tubes not include welds used for joining lengths of flat rolled strips prior to forming the pre-tube

Applications

For Auto industry/for Machinery use/Oil Cylinder Tube/Motorcyle Shock Absorber,inner cylinder/Telescopic Cylinders

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
