Product Detail
Cold Drawing Carbon Steel Tube E215 , Precision Steel Tube EN 10305-1/4
<p
Cold Drawing Carbon Steel Tube E215 , Precision Steel Tube EN 10305-1/4
1.Precision steel tube-carbon steel are made using the cold drawing process. Precision tubes are made from carbon steel from quality Bao Steel,XingCheng Steel,and HuaiSteel.
2. The tubes are high precision in tolerance,excellent surface brightness,no oxidization on the outer and inner walls after heat treatment,high cleanness of inside wall.
3. No deformation after cold bending,no crack after flaring and flattening.
