What Are Chrome Polished Rods?​

Chrome polished rods are high-grade steel rods with a ​mirror-like chrome finish, offering ​exceptional hardness, corrosion resistance, and smooth surface quality. These rods are widely used in ​hydraulic cylinders, linear motion systems, industrial machinery, and automotive applications​ where precision and durability are critical. ANBAO HYDRAULIC specialize in manufacturing ​top-tier chrome polished rods​ with ​strict quality control, advanced processing techniques, and decades of industry expertise. Our products meet ​ISO, ASTM, and DIN standards, ensuring reliability in the most demanding environments.



How Are Chrome Polished Rods Manufactured?

​Step 1: High-Quality Steel Selection​

We start with ​precision-drawn, cold-rolled steel bars​ (grades like ​1045, 4140, or stainless steel) to ensure ​high tensile strength and dimensional accuracy.

​Step 2: Precision Turning & Grinding​

✔ ​Centerless grinding​ ensures ​tight tolerances (±0.005mm)​​ and a perfectly cylindrical shape.
✔ ​Hard chrome plating​ (thickness ​20-50 microns) is applied for ​wear and corrosion resistance.

​Step 3: Superfinishing & Polishing​

Our advanced polishing process includes:
✔ ​Multi-stage abrasive polishing​ for a ​Ra ≤ 0.1µm surface roughness​ (ultra-smooth finish).
✔ ​Electrolytic polishing​ (for stainless steel rods) to enhance ​corrosion resistance and aesthetics.

​Step 4: Quality Inspection​

Every rod undergoes ​strict testing, including:
✔ ​Hardness testing (HRC 60-65)​​
✔ ​Surface roughness analysis​
✔ ​Dimensional accuracy checks​
✔ ​Salt spray testing (500+ hours for corrosion resistance)​

How To Choose The Cylinder Barrel Materials

Image
  The  cylinder barrel   in which the piston operates must be made of a high-strength material, usually steel. It must be as light as possible, yet have the proper characteristics for operating under high temperatures. It must be made of a good bearing material and have high tensile strength. The cylinder barrel is made of a steel alloy forging with the inner surface hardened to resist wear of the piston and the piston rings which bear against it. This hardening is usually done by exposing the steel to ammonia or cyanide gas while the steel is very hot. The steel soaks up nitrogen from the gas, which forms iron nitrides on the exposed surface. As a result of this process, the metal is said to be nitrided. This nitriding only penetrates into the barrel surface a few thousands of an inch. As the cylinder barrels wear due to use, they can be repaired by chroming. This is a process that plates chromium on the surface of the cylinder barrel and brings it back to new standard d...
