Carbon steel balances durability, hardness, and wear resistance using formability, weldability, and durability; Chrome plating provides corrosion resistance along with an Extremely reflective look High precision tolerances, which ensures when used to make hydraulic piston rod, it can fit the cylinder precisely. Good Hardness: the surface hardness attaining HV850 minimal and upward, which not only help improve wear resistance but also help extend the life span of these chrome plated rods, thereby helping the consumer save the cost. High performance of strength: The yield strength of chrome plated bars can be 75000 psi up to 100000 psi. Besides  chrome plated rods ,  Datong Hydraulic  also produce and supply induction hardened chrome plated cylinder rods. honed tube , hydraulic cylinder barrel ,  hollow chrome bar Want to buy chrome plate rods?

  high tensile 4140 induction hardened chrome bar made from chrome plated steel are typically used in applications where there are heavy duty conditions – often corrosive. The steel contains increased levels of alloying elements which delivers a high grade steel with superior tensile strength exhibiting good machining. 42CrMo4 chrome plated bar is manufactured from low-alloy chromium-molybdenum steel and supported by an induction hardened case offering greater strength and resistance to mechanical damage from external impact. It is used in applications requiring greater yield strength in combination with greater surface impact resistance.

  Cold Drawn Seamless Tubing  (CDS) is a cold drawn steel tube which offers uniform tolerances, enhanced machinability and increased strength and tolerances compared to hot-rolled products. Produced from hot rolled 1026, the cold drawing process increases the tube's physical properties and offers better tolerances and reduced machining allowances over hot finish seamless tube. Cold drawn seamless tube and pipe is produced by piercing hot billets and subsequent rolling which reduces their diameter and elongates them. This material is then passed through a die and over a mandrel plug to produce an accurate size and gauge which is the essence of the cold drawing process.

  Chrome hollow bar   we also call it chrome plated tubing,it is a kind of tube which inner surface is honed and the outer surface is chrome plated. The chrome plated surface provides excellent wear and corrosion resistant performance of the tube. Chrome plated steel tubing has an excellent durability and helps reducing friction. Chrome plated pipe is mostly used as hydraulic piston rods in order to have a lighter hydraulic cylinder. And chrome plated OD tube also can be utilized for applications where precision outside diameter or high smooth outside surface is  required. Chrome plated OD tubes can be supplied with honed inside surface for telescoping hydraulic cylinder applications too. Chrome hollow bar mainly suitable for elevator cylinder, telescope cylinder, scaling ladder, agriculture machines, engineering machinery, construction machinery etc.

honed hydraulic tube  is referred to as a Honed tube. One of the most important materials of manufacturing hydraulic cylinders are Honed Tubes. This type of tubing is ordinarily honed in the inside diameter of a Ready to Honed Tube. Which is why it is also known as honed ID tubing. Honing is an abrasive or a grinding machining process that delivers a precision surface on a metal workpiece for e.g.   Hydraulic Tubes .  During this process, an abrasive grinding stone or grinding wheel is scrubbed against a Pre Honed Tube along a hegemonized path. Honing is a process which is fundamentally used to enhance the geometric form of a surface. ADVANTAGES OF OUR HONING TUBE 1, High precision tolerances; Our honed steel 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 ...

  Metal tube and hollow bar are used in a wide variety of structural applications. They offer a cost advantage to solid metal bar stock, while weighing less than a solid bar of the same material and size, yet still providing much strength. While tube and hollow bar can be similar in shape, we will look at the difference between tube and hollow bar. The difference between tube and hollow bar include: Manufacturing Process Quality Materials MANUFACTURING PROCESS A big difference between welded tubing and  hollow bar  is how the two are made. Tube is made by taking slit coils of a base metal and running it through a tube mill, which is a series of dies that form the slit coil into a tube shape; either round, square, or rectangular for example. Once formed into the desired shape, the edges are joined together with a weld. The welding process can vary depending on the material type, material thickness, and preference of the manufacturing team. Typically, high frequency welding...

  S45C hydraulic cylinder chrome plated shaft   mainly used for hydraulic equipments and construction machinery . The Quenched and Tempered Shafts are fabricated using quenched and tempered S45C material and latest machinery. The bars undergo rigorous processes like pilling, quenching and tempering, straightening, grinding, polishing, hard chrome plating and finishing under the supervision of experienced engineers. The mechanical property of the Quenched and Tempered Shafts is better than the Hard Chrome Plated Piston Rods. The Quenched and Tempered Shafts are more qualified under adverse operating environment owning to its excellent mechanical property such as robust construction, elevated durability and high tensile strength.
