1026 Carbon Seamless H8 Precision Machining Honed Steel Tube For Hydraulic Pneumatic Cylinder

1026 Carbon Seamless H8 Precision Machining Honed Steel Tube For Hydraulic Pneumatic Cylinder   Grade C Si Mn P S Cr Mo 1026 0.22-0.28 / 0.60-0.90 0.040 max 0.050 max / / Description: Our honed tube is produced using our Suitable To Hone Drawn Over Mandrel (DOM) and Cold Drawn Seamless CDS. This honed tube 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.   Application: Hydraulic Cylinder, Hydraulic Jack, hydraulic oil cylinder pneumatic cylinder, petrifaction oil pump, coal mine, engineering machinery, crane and transport machinery, auto transmission axes, plastic machinery, engineering machinery, crane and transport machinery, auto transmission axes, plastic machinery, hydraulic oil cylinder, pneumatic cylinder, absorber, spin printing and dyeing. Main Features: 1. Roughness(Ra) can be 0.08µm or less. 2. Ovality can be 0.01 mm or less. 3, Hardness can be HV4° or higher.
