Cold Drawn Seamless Mechnical Tube (CDS)

Produced into A519 from 1010/1020/1026/1035/1045 etc carbon steel and various alloy grades such as SAE4130,4140.cold drawn seamless (CDS)  tubes have closer dimensional tolerances, better surface finish and higher mechanical properties than the corresponding grades of hot finished seamless tubes.

CHARACTERISTICS

Cold – worked mechanical tubing is normally produced to OD and wall thickness.  If the ID is a more important dimension then cold – worked tubing should be specified to the ID and wall thickness or OD and ID

Mechanical Seamless Steel Tubing 

We can supply seamless tubing with specific material/dimensional requirements, depending on customers’ demand.

Seamless tubing can be an ideal choice when high strength-to-weight ratio is required  and can be processed to provide a combination of desired characteristics, dimensional accuracy, good surface quality, excellent micro–structural uniformity, good machinability and high-tensile properties.

Applications:

Bushings

Spacers

Bearings and other mechanical parts in automobiles, aircraft, & drilling equipment

Hydraulic Cylinders

Automotive Tubular Parts
