HARD CHROME PLATE SHAFTS | CHROME PLATE SHAFTING
Hard chrome plated shafts, often referred to as chrome plated rods or bars, are typically crafted from steel rods. These rods undergo a meticulous process of precision grinding and polishing before being coated with a layer of hard chrome. This chrome plating varies in thickness, commonly around 20 to 25 microns, although other specifications are available to suit different requirements. Our factory, with over 20 years of expertise, stands as a premier manufacturer and supplier of these high-quality chrome plated shafts in China. We are committed to delivering exceptional products that meet a wide range of industrial needs.

OUR CHROME PLATED SHAFTS: RECOGNIZED FOR THEIR DISTINCTIVE FEATURES
a. The hard chrome surface of our shafts provides exceptional corrosion and wear resistance, combined with a very smooth finish, resulting in a low coefficient of friction. This not only ensures functionality but also offers an aesthetically pleasing and durable appearance.
b. The use of carbon steel in our shafts strikes an optimal balance between durability, hardness, and wear resistance, while maintaining formability, weldability, and robustness.
c. Precision-engineered to high tolerances, our shafts are ideal for hydraulic piston applications, ensuring precise fitment with the cylinder.
d. Our chrome plated shafts boast a high level of strength, with yield strengths ranging from 75,000 psi to 100,000 psi, depending on the material and heat treatment employed.
e. Superior Hardness: The surface hardness of our shafts reaches a minimum of HV850, enhancing wear resistance and extending the lifespan, which in turn provides cost savings for our customers.
f. Excellent Surface Smoothness: Our hard chrome plated shafting has a surface roughness of around Ra0.2μm (8 Ra), with a maximum of Ra0.4μm (16 Ra), ensuring a high-quality finish.
Before dispatch, each of our chrome plated shafts is meticulously coated with anti-rust oil to ensure long-term preservation. To further safeguard the integrity of the chromed surface, particularly on piston rods, we employ a protective cardboard (paper pipe) wrapping for each individual rod. This careful attention to detail extends to our shipping practices, where we utilize robust, seaworthy packaging options like wooden cases or secure rope wraps, guaranteeing the safe and intact delivery of our products.
