  AISI 1045  chrome plated shaft  is cold drawn, precision ground and polished shafting with a seam free surface finish of RMS 25 max. The bars are then hard chrome plated by electrolytically deposited layer of chromium metal on the surface. This hard chromed surface confers the important properties of corrosion resistance and wear resistance; it is also very smooth and therefore has a low coefficient of friction. Not least of all, it has an attractive and durable decorative appearance. Stainless Steel is an iron-based metal alloy, with added elements including chromium, nickel, silicon and carbon. These elements are mixed into the base material itself, and are present throughout the entire structure of the shafts.   The surface of the Stainless Steel is then finely polished to a mirror finish. Because the Stainless properties are evident throughout the entire bar, any damage or scratches can simply be re-polished to expose the fresh new material underneath. As a pro...

  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.

  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.

  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.

  CK45 Hard chrome plated bars  are chromium-plated steel products that can be supplied as piston rods in standard hydraulic and pneumatic applications. The chrome plated steel bar is normally used in conditions of high stress, friction and harsh climactic environments, so the quality of the base metal and subsequent surface treatment are of paramount importance. Wear resistance, corrosion resistance, surface smoothness, high yield strength and uniform quality are essential properties of hard chrome bar. Hard Chrome Plated Piston Rods are widely used in hydraulic and pneumatic cylinder, printing machinery, textile machinery, engineering machinery, wood working machinery, etc. Our products are highly appreciated by our clients for their features like corrosion resistance, robust construction, elevated durability, high tensile strength and the mirror-like surface. APPLICATIONS ￭ Hydraulic cylinder ￭ Pneumatic cylinder ￭ Precise machine pipes ￭ Agriculture mac...

Hard chrome plating is an electroplating process that involves applying a layer of chromium to a surface by submerging it in a chromic acid solution. Hard chrome plating can increase the durability, hardness, wear resistance and corrosion resistance of metal components for more effective use in machinery and equipment.it also creating a shiny and smooth surface that is easier to clean. For improved wear and corrosion resistance, it’s tough to beat hard chrome plating. The hardness and durability of a chromium metal surface finish means your parts will last longer even under severe mechanical contact and wear situations. A chrome surface also resists corrosion, making it suitable for use in harsh environments or where other plating materials would wear away, exposing the substrate metal to corrosion attack. How Long Does Chrome Plating Last? The longevity of any chrome plating depends on several factors: Surface preparation care and method Choice and qu...

  Hydraulic Cylinder rods   are chrome-plated steel products that can be supplied as  piston rods   in standard hydraulic and pneumatic applications. The chrome plated steel bar is normally used in conditions of high stress, friction and harsh climactic environments, so the quality of the base metal and subsequent surface treatment are of paramount importance. Wear resistance, corrosion resistance, surface smoothness, high yield strength and uniform quality are essential properties of hard chrome bar.Common applications are found in agricultural machinery, production equipment, cranes, garbage compactors, lifters etc. The piston rod is typically a hard chrome-plated piece of cold-rolled steel that attaches to the piston and extends from the cylinder through the rod-end head. In  double rod-end cylinders , the actuator has a rod extending from both sides of the piston and out both ends of the barrel. The piston rod connects the hydraulic actuator to the machine c...
