China ASTM Seamless Steel Tube Pipe Precision Tube

ASTM Carbon Steel Tube/Pipe Precision Tube Pipe/Pipe
Metric Honed Tubing

Metric Honed Tubing: Our honed tubing is produced using our Suitable To Hone Drawn Over Mandrel (DOM) and Cold Drawn Seamless CDS. This tubing is ready to use for hydraulic cylinder applications without further ID processing. The honing process involves using abrasive polishing stones and abrasive paper to remove small amounts of material, to produce extremely precise ID dimensions and improved finishes.

Made from 1026 or ST52.3 Drawn over mandrel and cold drawn seamless tubing.stocked to plus side tolerances and also stocked to minus side tolerances.Stocked Size Range: 1-1/2" - 14" Honed ID; 3/16" - 1" wall thicknessStocked in 20' random lengthsCut to length sizesImperial and metric sizesSuitable to hone sizes16 Max RMS ID FinishWe can process to your custom sizeD.O.M.
