Jiangyin Deshun Hydraulic Machinery Co., Ltd.  

Product Name: E355 Cold Drawn Seamless Steel Pipe for Truck and Automotive Parts Model NO.: C345-2 Usage: Hydraulic Cylinder Qualification: ISO9001; SGS Craft: Cold Drawn, Skived and Roller Burnished Materials: E355 Wall Thickness: 5-28.5mm Trademark: Deshun Transport Package: Bundle Packing, Slightly Internal and External Oi Specification: ID: 125-250mm Origin: China HS Code: 7304319000 Product Description Cold Drawn SeamlessMechanical Tube (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.Made from 1020 steelMeet DIN2391Standard size range: 1.500"OD - 14.000" OD; 0.25" wall - 1.25" wallStandard lengths Max 36'Cut to length service availableBenefits of Cold Drawn Seamless Mechanical Tube:Superior surface finishHigh yield strengthDimensional accuracy and excellent micro-structure uniformityEnhanced machinabilityHigh strength to weight ratioTight tolerances, resulting in reduced machine timePossible spiraling eccentricity inherent in product Need a custom size? We can do that too!Other Tubes and Tubings:1. Suitable to Hone Mechanical Tubeis 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.2.Honed Tube:Deshun's hydraulic cylinder tube is produced using our "Suitable To Hone" 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 tube is ready to use for hydraulic cylinder applications without further ID processing.3. Inch Honed Tube: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 Tube: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 Tubeis 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.6.Bore Tube also calledSRB finishedare used at telescopic hydraulic cylinders. The chrome surface is giving good wear and corrosion resistance. The boring process is a complex process that is increasing the roughness qualities of the surface. The skiving knives pass first scraping the inside layer of metal. Burnishing rollers are passing afterwards cold working the tube and creating an internal mirror surface finish.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 RollingScopeCDS tubefor hydraulic cylinder, crane,injectionmachineandconstructionmachineapplicationManufacturing Process:Appllications:Hydraulic cylindersRollersStructural applicationsTruck and Automotive partsHeavy equipmentAgricultural componentsCompany Profile:Jiangyin Deshun hydraulic machinery Co., LTD, is located in the Yangtze river delta-jiangyin.
