Overall, the combination of advanced processing techniques, selective material choice, induction hardening, and hard chrome plating results in a superior hollow bar suitable for robust piston rod applications.
Induction Hardened Hollow Bar
The Induction Hardened Chrome Plated hollow bar you mentioned is produced using advanced processing techniques. Here are the key details:
Material: The hollow bar is typically made from steel rods such as JIS S45C, SAE1045, or DIN CK45. These materials are known for their high strength and mechanical properties.
Processing Steps: The production process involves several steps:
Surface Removal: The surface of the steel rod is carefully prepared by removing any impurities or imperfections.
Polishing: The rod undergoes a polishing process to achieve a smooth and uniform surface finish.
Induction Hardening: The rod is subjected to induction heating, a heat treatment process that increases the hardness and strength of the material. This step enhances the rod's resistance to external impacts and tough environments.
Hard Chrome Plating: After induction hardening, the rod is plated with a layer of hard chrome. The chrome plating thickness is typically a minimum of 0.0005" or 0.001" per side. Hard chrome plating provides superior corrosion resistance and further enhances the rod's durability.
