What is the suitable material for cylinder piston rod?


The cylinder piston rod is not just the object transmitting the force from the cylinder’s piston but also the interface between that cylinder and your machine. Before you can correctly select and then design the piston rod, you must understand the materials for cylinder piston rods. The following are the top  common piston rod materials on hydraulic cylinders.

Most commonly, the cylinder piston rod is made of carbon steel or stainless steel like CK45, SAE1045, 4140, 4340, SAE1518,SAE4145,JIS45C, 40Cr, 20MnV6, 42CrMo, SS431, SS430, Stainless Steel 304/316/2205, etc.and is then coated with Hard Chrome Plating (HCP).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 hydraulic cylinder rods is called “Hard Chrome”. It is dull silver / grey in color, and as the name suggests, has a hard surface. Delivery Condition: Normal, Q+T, Induction hardened.

Application of 4140 chrome bar

Image
4140 is a 1% Chromium - Molybdenum high tensile steel supplied in the hardened and tempered, cold drawn or turned, precision ground, polished, chrome plated and final polished condition, with a typical base metal tensile strength of 850 - 1000 Mpa, plus a typical hard chrome plated surface hardness of HV 1000 - 1150.Characterised by an extremely smooth surface finish with excellent wear and corrosion resistance, coupled with a base material giving high strength and good impact properties, plus good machinability. 4140 hard chrome plated bar is used extensively by the hydraulic and pneumatic industries, and is employed by other industry sectors for a wide range of applications requiring higher strength. Typical applications are: Agricultural Equipment, Hydraulic Cylinders , Hoists, Jacks and other Lifting equipment, Machine Tools, Mining and Earth Moving Equipment, Pumps, Valves, Waste Disposal Transport and Equipment etc. Anbao Hydraulic is a professional manufacturer in

The Production Process Of Chrome Plated OD Tubing

  Chrome plated od tubing is also known as chrome plated hollow bar ,chrome plated tubing a very important part for producing hydraulic piston rods and roller shafts in various machines. The biggest advantage of chrome plated od tubing than normal chrome plated rod is that the unit weight is light, people can greatly reduce the weight of the hydraulic piston rod, when design the hydraulic cylinders . The Production Process Of Chrome Plated OD Tubing Step 1. Get the steel tubes heat treated as per customers’ request. Step 2. Cutting the raw material hollow rod into lengths Step 3. Straightening the hollow rods Step 4. Peeling on the steel hollow rods Step 5. Straightenning Step 6. Grinding the steel hollow rods Step 7. Straightening the ground hollow bars. Step 8. The second grinding process Step 9. Polishing on outer diameter surface Step 10. Chrome plating Step 11. Final polishing Step 12. Final inspection Anbao Hydrualic is a professional  chrome plated ID tubing and hollow bar m
