How Does 4140 Chrome Piston Rod Made?

 4140 chrome piston rod, which is a specific type of hard chrome rod, because the material is 4140 steel, so this kind of hard chrome rod is called 4140 chrome plated bar. The familiarity and understanding of this product is to use the product correctly and reasonably, and further, it can have a good use effect on the use of the product.

The process of 4140 chrome piston rod?

Hardening
High-frequency induction hardening guarantees the surface hardness and optimum strength of the material, which makes the shaft highly durable and resistant to abrasion. We can supply several conditions as follows:
1, Hard chrome plated (surface without heat treatment)
2, High-frequency induction hardened hard chrome plated
3,Quenched and Tempered
4,Induction hardened with Q&T

grinding
Our grinding lines work at high processing speeds with optimum efficiency. Depending on material and diameter requirements, surface qualities with roughness specifications up to Ra 0.2 µm can be obtained.

Surface treatment
By hard chrome plating, your components obtain a high resistance to corrosion and wear. This means high endurance over the entire life of the product. Usually, the thickness of hard chrome plating is 10μm ~ 15μm.Resistance in front salt spray (fog) test environment according to the ASTM B-117-97 could be 36 hours.

Polishing
We can guarantee you mirror-like polished surfaces with our optimal finish grinding method - without material loss.

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
