Overall, the Hollow Chrome Plated Rod offers a combination of strength, weldability, low-temperature endurance, precise grinding, hard chrome plating, and tolerance to international standards.
Hollow Chrome Plated Rod
The Hollow Chrome Plated Rod, also known as the Hollow Piston Rod, offers several advantages:
Higher Yield Strength: The rod is designed to have a higher yield strength, which ensures its ability to withstand heavy loads and pressure. This feature enhances the overall strength and durability of the rod.
Good Weldability: The rod is easy to weld, allowing for convenient fabrication and assembly in various applications. It enables efficient joining with other components without compromising the structural integrity.
Low Temperature Enduring Assault Performance: The rod demonstrates excellent performance and endurance under low-temperature conditions. It maintains its mechanical properties and remains reliable even in challenging environments with extreme cold temperatures.
Precise Internal Grinding: The internal surface of the rod undergoes precise grinding, ensuring a smooth and accurate finish. This precision is crucial for applications that require optimal sealing and performance, such as hydraulic cylinders.
External Hard Chrome Plating: After precise grinding, the external surface of the rod is hard chrome plated. This chrome plating layer provides enhanced corrosion resistance, wear resistance, and durability. It helps protect the rod against external elements, ensuring a longer service life.
Tolerance to International Standards: The rod's dimensional tolerance meets international standards, ensuring compatibility and interchangeability with various systems and components across different industries.
