What is 1045 chrome plated bar?
1045 chrome plated bar is also called 1045 chrome bar or 1045 chrome rod for short sometimes, it is the hard chrome plated shafts made of steel grade SAE 1045.
The 1045 chrome plated rod is a medium carbon steel with the SAE 1045 specification that is supplied in a polished, chrome plated and final polished condition. It has a tensile strength range of 670 to 800 Mpa and a yield strength of around 520 Mpa (75Ksi).
The SAE 1045 steel is equivalent to the German standard CK45 or C45, making the 1045 chrome plated rod also known as CK45 chrome plated bar or CK45 Chrome rod.
Here below is the chemical composition and mechanical properties of SAE 1045 and CK45.

- Reliable Packing: All the chrome plated shafts will be oiled by the anti-rust oil before delivery. And to protect the outer surface of the chroming of piston rods, we will use cardboard (paper pipe) to pack each rod, and then pack with seaworthy package such as wooden cases or rope wraps.
- Strictly Quality Management: Our factory has a QC team of more than 10 persons. All the chrome rods will be inspected before delivery. The inspections including: Chemical Analysis Test, Tensile Test, Dimension Inspection, Roughness Testing, Chrome plated thickness test and other tests according to standards and cusotmer’s requirements.
- Mature quality management system: our Total quality management system ensures all the working processes related to product quality are in good control.
- High precision dimensions: Our chrome plated rods are manufactured with high dimension precision, tolerance can be ISO f7, f8 or g6, upon request. Which ensures the precision of the hydraulic cylinders or the machineries.
- High smooth surface quality, surface roughness max. 0.2 microns.
- Higher yield strength: our chrome plated bar is with standard yield strength of min. 517 Mpa (75 ksi), and we can also supply chrome plated rod with yield strength of 10000 ksi and 15000 ksi up on customers’ requests.
