Product Description

E355 Seamless Mechanical Cold Drawn Steel Tubing 


 Cold Drawn Seamless Tubes (Mechanical and Hydraulic)
Used in applications requiring high strength. Cold Drawn Seamless tubing (also known as CDS). Cold Drawn Seamless tubes offer tight tolerances compared to Hot Finished Seamless tube, and offers stronger physical properties compared to other mechanical tubing. CDS is popular in the hydraulics, being used to make hollowed chrome plated telescopic cylinders and hydraulic rods. It is also popular for large bore, heavy walled, high pressure hydraulic cylinders. Cold Drawn Seamless tubes also find uses in heavy equipment manufacturing such as cranes and garbage trucks.
