Honed Tubing: Hydraulic cylinder tubing is produced using our “Suitable To Hone” Drawn Over Mandrel (DOM) and Cold Drawn Seamless (CDS). 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. Honed tubing is ready to use for hydraulic cylinder applications without further ID processing.

· Made from grades 1020/1026 and ST52.3 ,4130,4140

· Size Range: 1.0” ID – 14.0” Honed ID; 1/8” – 1” wall thickness

· Stocked in 17’ - 24’ random lengths

· Cut to length service available

· Standard and metric sizes

· Suitable to hone sizes

· 14 Max Ra ID Finish
