China ASTM Cold Drawn Seamless Steel Pips Tube

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 steelMeet ASTM A519Stocked size range: 1.500" - 14.000" OD; .2500" - 1.2500" wall thicknessStocked lengths 8'-24'Cut to length available

Benefits of Round Cold Drawn Seamless Mechanical Tubing:

Superior surface finishDimensional accuracy and excellent micro-structure uniformityEnhanced machinabilityHigh strength to weight ratioTight tolerances, resulting in reduced machine timeApplications: hydraulic cylinders, rollers, structural apps, truck and automotive parts.Seamless Mechanical Tube Tolerance
