Product Description

ASTM Seamless Carbon Steel Tube/Pipe Precision Tube Pipe/Pipe


Cold Drawn Seamless Mechanical Tubing (CDS) is a cold drawn 1018 / 1026 steel tube which 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
• Meet ASTM A519
• Stocked size range: 1.500" - 14.000" OD; .2500" - 1.2500" wall thickness
• Stocked lengths 8'-24'
• Cut to length available

Benefits of Round Cold Drawn Seamless Mechanical Tubing:

• Superior surface finish
• Dimensional accuracy and excellent micro-structure uniformity
• Enhanced machinability
• High strength to weight ratio
• Tight tolerances, resulting in reduced machine time
• Applications: hydraulic cylinders, rollers, structural apps, truck and automotive parts.
