Product Introduction
Products Description
Our hardened chrome rod is a precision-engineered steel rod widely used in hydraulic cylinders, pneumatic systems, and various industrial machinery. Manufactured from high-quality carbon steel or alloy steel, the rod is induction hardened and plated with a hard chrome layer to ensure superior strength, wear resistance, and surface smoothness. With excellent corrosion resistance and dimensional accuracy, our hardened chrome rod guarantees reliable performance in demanding environments.
Product Advantages
- High Surface Hardness-The induction-hardened surface and chrome plating extend the service life of the rod.
- Superior Wear Resistance-Designed to withstand heavy-duty operations and reduce friction loss.
- Corrosion Protection-High-quality chrome layer provides strong resistance to rust and oxidation.
- Excellent Straightness & Precision – Ensures stable movement in hydraulic and pneumatic applications.
- Long Service Life – Lower maintenance requirements, reducing downtime and cost.

FAQ--chrome rod
Q: What is a hollow piston rod?
A: A hollow piston rod is a cylindrical rod with a hollow core, designed to reduce weight while maintaining strength.
Q1: What is the difference between a hardened chrome rod and a regular chrome-plated rod?
A: A hardened chrome rod undergoes induction hardening treatment, providing higher hardness, wear resistance, and durability compared to a standard chrome-plated rod.
Q2: Can you produce non-standard sizes?
A: Yes, we offer customized diameters, lengths, and machining services according to your drawings and requirements.
Q3: How do you ensure the quality of your hardened chrome rods?
A: Every rod is strictly tested for straightness, hardness, chrome thickness, and surface finish before delivery.
Q4: Do you accept small trial orders?
A: Yes, we welcome trial orders to support new customers and projects.
Q5: What is the lead time for bulk orders?
A: Normally 7–20 days, depending on order quantity and customization level.
