  Stainless steel honed tube  has widely usage in industry machine like hydraulic cylinder design and repair.  Stainless steel honing tubes show strong corrosion resistance due to the addition of a higher content of chromium Cr element.   Cr element is easy to oxidize, can quickly form a compact Cr2O3 oxide film on the surface of steel, prompting the steel electrode electricity and corrosion resistance in the oxidation medium mutability . Stainless steel honed tube has better corrosion resistance than carbon steel honed tube like  ST52 honed tubes . THE BENEFITS OF STAINLESS STEEL HONED TUBE: High tensile and yield strength Excellent machinability Corrosion resistance Wuxi YUTONG  is a very professional manufacturer of of stainless steel  hydraulic honed tubing  and Piston Rods, in a variety of bore sizes and in various grades including 304, 316, 2205 and 2507. Small quantities are also available for us. pls  contact us here  if you have any inquiry for honed tubes or  chrome plated ba

  E355 ST52 Honed tube  is very widely used as cylinder barrel in hydraulic cylinder design and repair. It is the core part of the hydraulic cylinder.  Honing is a processing technique. Through the honing head, the reciprocating high-speed grinding technology is used to process the inner hole of the cold drawn pipe, so that the inner hole meets the requirements of the tolerance size and surface roughness we need. The advantages of our ST52 honed tubes 1. High precision tolerances;  Wuxi YUTONG ’s honed tube can meet ID tolerance H7, H8, H9, … etc according to the customer’ requirements, and its I.D dimension. 2. Seamless tube with high pressure resistance;We only use  seamless cold drawn tubes  to produce honed pipes, which means our honed tubing can work under higher pressure, thus our honed pipes are more reliable for hydraulic cylinder applications. 3.   Advanced manufacturing equipment and facilities, including: cold drawing machine, cold rolling machine, honing machine, skiving &a

  Cylinder barrel tube （Honed tube) is the most important part to manufacture and repair hydraulic cylinders. This is because honed tubes are the most critical materials for hydraulic cylinders. Honing is essentially a bore sizing and surface preparation process.    The honing process of cylinder barrel tube is mostly utilized to produce smoothly inside surface finishes, and to ensure accurate dimension tolerances on inside diameters.It will uses abrasive stones and paper to machine the inside diameter of the cold drawn seamless tubes , which “grinds” stock away to eliminate the surface defects from the cold drawing process; and to reach the required tolerances and surface roughness. And usually we should use cutting fluids to offer easy cutting action and also to clear away the cut material from the inside surface. The advantages of honing process for cylinder barrel tube? High processing accuracy of the inside diameters Good surface quality: the surface of honing is cross-grain, whi

  Chrome plated rod   is a very important material as cylinder rod for hydraulic cylinders and pneumatic cylinders. Usually we use steel round bar to produce hard chrome rod, materials like Ck45 1045 4140 42CrMo4 SS304/316 to keep the cylinder rod good working performace. The heat treatment process is also very important to  chrome cylinder rod . Normally the chrome plated bars are supplied with a certain heat treatment process. The heat treatment will provide the chrome plated rod with higher strength, high hardness and lower residual Stress. There are 3 main heat treatment process for chrome plated steel bar as below. Quenching and tempering heat treatment: Q&T treatment is the most popular heat treatment for hard chrome plated rods, most of the materials of chromed rods such as CK45, SAE1045, 4140, 42Crmo4 can be Q&T heat treated. Induction hardened heat treatment Induction hardened heat treatment usually is applied to get higher hardnen for the piston rods, chrome plated ba

  Honed cylinder tube   or  skived & roller burnished tube  is a very important part in cylinder building. honed cylinder tube is known as honed tubing also, it is usually made of cold drawn seamless tubes , as hydraulic cylinder tubes are usually used to manufacture hydraulic cylinders body, so it is called hydraulic cylinder barrel commonly. There are many different steel grades can be used as the material of hydraulic cylinder tubes, and here below are the most popular materials. Carbon steel ST52, ST52.3, Carbon steel E355 Carbon steel SAE 1020, Chinese 20#, C20 Steel SAE  4140 : also known as 42CrMo or 42CrMo4 Steel 4130 4340 34CrMo4 35CrMo Stainless steel 304 Stainless steel 316 ST52 HONED CYLINDER TUBES ST52 honed cylinder tubes  are honed tubes made of material steel grade ST52, and with standard of DIN 2391. St52 is equal to St52.3. Usually this materials of honed tubes are describled as: cold drawn seamless honed tubes as per DIN2391 /ST52-BKS. BKS standards for the heat
