 In the world of hydraulic systems, every component plays a critical role in ensuring efficiency, reliability, and longevity. Among these components, the CK45 chrome piston rod stands out as a linchpin for seamless operation.  As a key element in hydraulic cylinders, CK45 chrome piston rods are engineered to withstand extreme conditions while delivering unmatched performance. Let’s dive into why chrome-plated piston rods are indispensable and how our expertise sets us apart in this competitive industry. Core Strengths of CK45 Chrome Piston Rods Superior Corrosion Resistance Chrome plated rods are coated with a thick, hard chromium layer, providing exceptional resistance to rust, chemicals, and abrasive environments. This makes them ideal for industries like marine, construction, and agriculture, where exposure to moisture and harsh elements is unavoidable. Enhanced Wear Resistance The ultra-smooth surface of chrome-plated rods minimizes friction between the piston and custom...

  CK45 Induction hardened chrome bar    is a material favored by hydraulic cylinder manufacturers. It is widely used to manufacturer cylinder piston rod, so it is also called CK45 hydraulic piston rod. The bars are centerless ground, polished, and chrome plated to a minimum thickness of 0.0007″, and 0.002″ per side. The production process medium tensile carbon steel CK45 in the cold drawn or turned, precision ground, polished, chrome plated and final polished condition. The tensile strength of CK45 steel is 670 – 800 Mpa, and yield strength around 520 Mpa (75Ksi).  The Induction hardened chrome plated rod results in a superior impact resistant bar ideal for high quality piston rods capable of handling tough environments.

  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.

  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...

  CK45 /AISI 1045 steel  shows reasonable strength and toughness. AISI 1045 will through harden to 2.5” (63mm) with a tensile strength of 66-120 Ksi (620-850 MPa) . This grade of steel is used for axles, bolts, forged connecting rods, crankshafts, torsion bars, light gears, guide rods etc . HEAT TREATMENT OF AISI 1045 (CK45)  AISI1045 (CK45)  Annealing Full annealing of small C1045 forgings is carried out from 1450-1600ºF (790-870ºC) followed by furnace cooling at 50ºF (28ºC) per hour, to 1200ºF (650ºC) soaking and air cooling. AISI 1045 (CK45)  Hardening Hardening of this grade is carried out from an austenitizing temperature of 1475-1550ºF (800-845ºC) and oil or water quenching. Flame and induction hardening may be carried out by heating quickly to the desired case depth and quenching in water or oil. This should be followed by a  tempering  treatment at 300-400ºF (150-200ºC) to reduce stresses in the case without affecting its hardness. A surface ha...
