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 SAE1020/1045 ST45 CK45 ST52 E355 27SiMnSize Range: 1.26" ID - 12.6" Honed ID; 1/5" - 1" wall thicknessCut to length service availableStandard and metric sizesSuitable to hone sizes0.8 Max RaID FinishNeed a custom size? We can do that !Other Tubes and Tubing:1.Cold Drawn SeamlessMechanical Tubing (CDS)is a cold drawn 1020 steel tube. Produced from piercing hot rolled bar stock, the cold drawing process increasesthe tube'sphysical properties reducing the cost of machine time. Cold drawn seamless tubing provides a better uniformed OD and ID, enhanced machinability, increased strength, and tighter tolerances compared to hot finish seamless products.2. Suitable to Hone Mechanical Tubingis produced from either Cold Drawn Seamless (CDS) Tubing or Drawn Over Mandrel (DOM) Tubing. Suitable to Hone Tubing is intentionally produced with an oversized wall thickness, which is intended to be honed to a smooth finish ID for cylinder applications. By utilizing suitable to hone tubing, machine time is reduced and waste is minimized.3. Inch Honed Tubing:Our 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.4. Chrome Plated OD Tubing:Deshun's Chrome Plated OD tubes are produced from Cold Drawn Seamless (CDS) tubing in grades 1020 andST52. The outside diameters are centerless ground, polished, and chrome plated to a thickness of .0007" - .002" per side. Chrome OD tubes are also offered with a honed inside diameter for Telescoping Hydraulic Cylinder applications.5. Chrome Plated ID Tubingis produced from Drawn Over Mandrell (DOM) or Cold Drawn Seamless (CDS) in 1020/1045 or ST52 grades. The inside diameters are polished, and chrome plated to a thickness of .0007" - .002". Custom diameters and chrome plating can be made to your specifications.Specification:StandardDIN2391, EN10305, ASTM A519, GB/T 8713 etc.MaterialST45, ST52, E355, E355SR, STKM13C, 27SiMn SAE1020, C20Q235B, CK45, etc.HeattreatmentBK+S conditionSpecificationOuterdiameter(mm) Innerdiameter(mm) 50-37740-320I.DToleranceH8~H9Length3-9 Mtr(Suggested length 3-5.8 Mtr suitable for 20' container)Straightness0.3/1000IDroughnessRA0.4 micron(max)TechnologyHoning / Cold Drawn / Boring and RollingScopeHoned tubefor hydraulic cylinder, crane,injectionmachineandconstructionmachineapplicationManufacturing Process:Appllications:Company Profile:Jiangyin Deshun hydraulic machinery Co., LTD, is located in the Yangtze river delta-jiangyin.
