The Application Of 1045 4140 Hard Chromed Bar

 Hard chromed bar is a chromium-plated steel product used primarily as piston rod material in all standard applications in hydraulics and pneumatics. Common applications are found in cranes, dump trucks, lifters, garbage compactors, agricultural machinery and production equipment with movable sections.

Because hard chromed bar is normally used in conditions of high stress, friction and harsh climatic environment, the quality of the base metal and surface treatment are of paramount importance. Wear, impact and corrosion resistance, as well as high yield strength, surface smoothness and uniform quality are most important properties of hard chrome bar.

The basic grades of steel used in the hydraulic filed are 1045, 4140 hardened and tempered,1045 induction hardened.

  • Grade 1045 induction hardened chrome steel bar is primarily used in hard chrome bar manufacture due to its wide range of properties consistent with end use applications.
  • Grade 4140 is used in applications where greater yield strength is required and induction hardened grade 1045 is used in applications requiring greater surface impact resistance.

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
