Cold Drawn Seamless Tubing

As a leading metals distributor for over 65 years, Industrial Tube and Steel Corporation provides a variety of Cold Drawn Seamless Mechanical Tubing (CDS) options. Cold Drawn Seamless (CDS) Tubing is a cold-drawn 1018/1026 steel tube that offers uniform tolerances, enhanced machinability, and increased strength and tolerances compared to hot-rolled products. Produced from hot rolled 1026, the cold drawing process increases the tube's physical properties and offers better tolerances and reduced machining allowances over hot finish seamless.

Made from 1018/1026 steel
Meets ASTM A519 (Cold Drawn)
A519 CDS Tubing Tolerances

Stocked Size Range

  • 0.250" to 10.000" O.D. with 0.035" to 1.500" Wall Thickness
  • Stocked in 17.000' - 24.000' random lengths (cut to length available)

Manufacturing Process of Cold Drawn Seamless (CDS) Tubing

Cold Drawn Seamless (CDS) seamless tube and pipe is produced by piercing hot billets and subsequent rolling which reduces their diameter and elongates them. This material is then passed through a die and over a mandrel plug to produce an accurate size and gauge which is the essence of the cold drawing process.

Benefits of Cold Drawn Seamless Tubing

Higher strength & hardness properties

  • Cold drawing increases the strength of the tube therefore making it very suitable for safety and performance critical applications.

Size accuracy

  • Due to the nature of the manufacturing process drawn tubes can be manufactured to close dimensional tolerances, achieving consistent diameter and thicknesses throughout.

Enhanced appearance

  • Cold drawn seamless tube usually has a shinier look with no weld lines increasing the aesthetics of the products in which it is incorporated.

Uniform micro-structure

  • Due to the cold drawing process, CDS has excellent micro-structure uniformity and consistency.

Easier to machine

  • Due to the superior strength and hardness, it produces a better machined surface and therefore a better-looking component.

Superior finish in subsequent manipulations

  • As cold drawn tubes have a glossier, no-seam finish they also produce better end products from processes such as dipping, etching and anodizing.
