 Hard chrome plating, also known as hard chromed , is a technique of electroplating that applies a thin layer of chromium onto a cylinder piston rod . Chrome plating is used to provide a working surface that requires one or more of the following characteristics: to reduce friction, resist abrasion, or increase corrosion resistance. It is very hard, measuring between 66 to 70 HRC.  Surface defects and roughness are amplified because hard chrome does not have a leveling effect. Friction between a Anbao cylinder rod and its seals, and the resulting wear, has a crucial influence on the efficiency and service life of a hydraulic cylinder . Chrome plating is a cost-effective repair option that can allow salvage of a cylinder rod, cylinder tube , or valve spool instead of replacing it with new. In addition to the cost benefits, chrome plating also creates a hardened wear surface, extending the life of most high wear areas resulting in longer run times between repair or re...

The high frequency piston rod or induction hardened piston rod is processed by high frequency quenching technology, and then polished by mirror surface. The hardness can reach HRC58-62. Compared with ordinary piston rod, it has the characteristics of friction resistance and corrosion resistance.   High-frequency quenching is mainly used for surface quenching of industrial metal parts. It is a heat treatment method that causes a certain induction current on the metal surface, rapidly heats the surface of the parts, and then rapidly quenches the parts.   Principle of high-frequency quenching:   Put the piston rod with a hollow copper pipe wound as sensor, after the ventilation with high frequency alternating current (ac), formed in the surface with the frequency of the induced current, the workpiece surface or local heating quickly (within a few seconds to heat up to 800-1000 degrees Celsius, the center is still close to room temperature) several seconds after...

  The Hard Truth Of hydraulic Cylinder Rod Anyone who has worked with hydraulic cylinders is familiar with the general structure and function of this linear actuator, and most understand the importance of protecting the rod from damage which often requires hydraulic cylinder repair. Scoring, pitting, or nicks in the chrome surface will ruin seals and result in fluid leaking from the cylinder gland – a problem that will only worsen with each stroke of the cylinder. What many don’t realize, is that not all cylinder rods are created equal, and the difference lies just below the polished surface. The polished surface is chrome plating. Chrome plating not only offers durable long-term protection against corrosion, but also provides a smooth finish that can be ground and polished to a precise diameter. This is critical to optimizing seal performance and providing enough clearance to allow lubrication between the rod and seal, but not outright leakage. The chrome plating used for hyd...

 The hydraulic cylinder 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 component doing the work. This connection can be in the form of a machine thread or a mounting attachment. The piston rod is highly ground and polished so as to provide a reliable seal and prevent leakage. The cylinder rod is the only external part that can’t be painted. Because of this, it has to be protected in other ways. In order for the cylinder to work well the coating has to be completely smooth. The cylinder rod needs to be highly resistant to pitting, corrosion or wear. Any cracks can scrape on seals, causing contamination to enter the hydraulic fluid and leading to eventual hydraulic system breakdown. Therefore, th...

  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. The piston rod material 42CrMo4 hardened and hard chrome plated with the material number 1.7225 is suitable for heavy use and is especially wear-resistant thanks to its hardened surface layer with a surface hardness of 56–64 HRC. Due to the material's high stability very high forces can be transmitted, e.g. for small connecting threads with large piston rods. Hard chrome plating means that an especially thick chrome layer is applied after the pre-honing and before finishing the honing process. The layer thickness depends on the rod diameter and has a hardness of more than 800 HV. Hard chrome plated piston rods can be used between -15°C and 200°C. Applica...

  Hardness measurement of  hydraulic cylinder piston rod  is usually divided into two kinds: destructive measurement and non-destructive measurement. Nondestructive measurements are less damaging and cannot be completely damaged. This injury is fatal in comparison to a piston rod, and therefore can only be done by destructive measurements. Piston rods sometimes deform after nitriding. At this time, has reached the finished size requirements, and the surface hardness is very high. It cannot be refined by processing methods. Only the straightening method can be used to control the deformation at a reasonable level. In the range. Commonly used pressure straightener, whether hot or cold, its straightening accuracy is artificially affected, can reach 1 to 2 mm. Usually, the bending deformation of some products after the nitriding of the piston rod is 0.1 to 0.3mm, so the deformation is very small and can not meet the requirements of the pressure correction machine. Bending and...

  Piston rod  is a connecting part that supports the piston to do work. It is mostly used in the  hydraulic cylinder  and cylinder movement execution part. It is a moving part with frequent movement and high technical requirements. Taking hydraulic cylinder as an example, it is composed of cylinder barrel, piston rod (cylinder rod), piston and end cover. The quality of its processing directly affects the life and reliability of the whole product. 1. After the heat treatment of the piston rod, the brittleness of the raw material of the piston rod was reduced to the minimum, so the toughness of the raw material of the piston rod was greatly improved. 2. After heat treatment, the impact toughness of the piston rod can be maximized under the condition of low temperature. In fact, the quality of the raw material of the piston rod can be improved from different aspects and the service life of the piston rod can be effectively extended. 3, after the piston rod heat treatmen...

  Hydraulic cylinder barrel  and cylinder  piston rod  due to the accident after bending, generally to be straightened on the pressure machine. However, the cylinder or piston rod straight after the colonel of the press will often rebound after a period of time, that is, the cylinder or piston rod to a certain extent to restore the original shape. For this reason, some repair shop after a long time of exploration, developed a long cylinder bending straightening machine . When in use, put the bent cylinder or piston rod into the straightening machine, press the clamping wheel, start the motor and roll it back and forth. Adjust the clamping wheel continuously according to the situation, and straighten the bending cylinder or piston rod slowly. This is different from the straightening in the pressure machine, straightening in the straightening machine, not only can straighten the bending part, and cylinder cylinder or piston rod because of bending the internal stress ca...

  The   quenched and tempered piston rods   are characterized by high strength and good ductility. Thermal refining: Generally, the heat treatment method combined of quenching and high-temperature tempering is called thermal refining, which is widely applied to various important structural parts, especially the connecting rods, bolts, gears and shafts working under alternating load. The tempered sorbite has better mechanical property than normalized sorbite of the same hardness. Its hardness depends on tempering temperature and relates to stability of tempering and sectional dimension of workpiece, and is generally HB200-350. Anbao Hydraulic  has been engaged in Quenched and Tempered Piston Rod , chrome plated bar , hollow chrome bar , honed steel tube ,for many years as one of the leading manufacturers and suppliers in China. Our products are of high precision, good performance and competitive price.if you have any inquiry please  contact us .
