What is CK45 chrome plated rod?
CK45 chrome plated rod is also called CK45 chrome rod or CK45 chrome bar for short sometimes. This product is the hard chrome plated bar made of steel grade CK45, it is widely used as the material of producing hydraulic cylinder rod, thus some people also call it CK45 hydraulic piston rod or CK45 hydraulic cylinder rod.
The CK45 chrome plated bar is a medium-tensile carbon steel made from CK45 material and supplied in a cold drawn or turned, precision ground, polished, chrome plated, and final polished condition. With a tensile strength of 670-800 Mpa and a yield strength of approximately 520 Mpa (75Ksi), CK45 steel is a strong and durable material.
CK45 is equivalent to the SAE 1045 standard, so this product is also referred to as the 1045 chrome plated rod or 1045 Chrome Bar. The chemical composition and mechanical properties of CK45 are provided below.
| Steel Grade | Chemical Composition % | ||||

The steel rods are grinded, polished and chrome plated, the surface quality is like below.
- Hard Chrome Plated Thickness:
Our CK45 chrome plated rod typically has a minimum chrome plating thickness of 20 microns (0.0008 inches) or 25 microns (0.001 inches). The maximum chrome thickness can be up to 50 microns, with other thickness options available based on customer requirements. Our factory’s chrome rods can withstand salt spray testing for a minimum of 48 hours in compliance with ASTM B-117 standards. - Surface roughness:
The surface roughness of our factory’s CK45 hard chrome plated bar is around Ra0.2μm(8 Ra), max. Ra0.4μm (16 Ra).
- Good hardness: Hard chrome plated surface hardness of Min. HV 900
- Super smooth surface finish with excellent wear and corrosion resistance
- High precision dimension tolerance
- The base material of the CK45 chrome plated bar offers robust strength and resilience to impact, as well as displaying good machinability and sufficient weldability properties.
Our factory, a professional supplier of CK45 chrome plated rods, ensures safe transportation by providing reliable packaging methods. Our standard packaging consists of a cardboard and rope or a wooden case. To preserve the smooth exterior diameter of the CK45 chrome bars, each bar is placed in a cardboard (paper tube) and then wrapped with ropes to form a bundle. Alternatively, the bars with their cardboard packaging can be placed in wooden boxes for added protection.
