Cold Drawn
Seamless (CDS)

Cold Drawn Seamless A519 tubing by PTC, offering superior strength, tolerances, and machinability, is ideal for demanding applications like hydraulic systems and heavy equipment.


Cold Drawn Seamless (CDS) tubing is used when heavy wall thicknesses, unweldable grades of steel, or both are required for a specific application. CDS affords superior dimensional tolerances, better surface finish, higher physical properties, and better machinability than Hot Finished Seamless.

CDS tubing inherently possesses a high strength-to-weight ratio and can be processed to provide a combination of desired characteristics: tight dimensional tolerances, good surface quality, excellent micro-structure uniformity, good machinability, and high tensile properties.

CDS is produced in standard carbon and alloy grades, as well as a variety of non-standard grades. 

PTC can supply Cold Drawn Seamless in any heat treat condition to customer specification. 

Common applications: 

  • Automotive & transportation components
  • Heavy equipment
  • Hydraulic cylinders
  • Hydraulic lines
  • Shaft tubing
  • Shapes
