**Product Description:**
Our hard chromium piston rods are manufactured using **JIS S45C** material, which ensures excellent mechanical properties. The process begins with precision machining, followed by surface chromium plating, resulting in a surface finish of **f7** and a hardness of **HV800 minimum**. This treatment significantly enhances wear resistance and extends the service life of the rod, offering long-term cost savings for our customers.
We also conduct internal corrosion resistance testing in our salt spray laboratory. The surface heat treatment reaches **HRC55° ± 2°**, with a hardened depth between **0.5mm - 3mm**. After this, the rods undergo precision milling and hard chrome plating, with a coating thickness of **20 microns ± 10%**, further improving durability and performance.

**Product Types:**
1. **Chrome Plated Steel Bars:**
These bars are made from medium carbon cold-finished or hot rolled steel, typically **1045 grade**. They are centerless ground, polished, and chrome plated to a minimum thickness of **0.0005"** on each side. Ideal for hydraulic and pneumatic cylinder applications.
2. **Induction Hardened Chrome Plated Bars:**
Produced using advanced techniques on **JIS S45C, SAE1045, or DIN CK45** steel rods. Surface removal, polishing, induction hardening, and hard chrome plating are applied to create a strong, impact-resistant bar suitable for harsh environments.

**Cold Drawn Seamless Mechanical Tubing (CDS):**
This type of tubing is produced from **1020 steel** and is cold-drawn from hot-rolled bar stock. The cold drawing process improves the tube's physical properties, reduces machining time, and provides better dimensional accuracy. It offers enhanced machinability, increased strength, and tighter tolerances compared to hot-finished products.
**Applications include:**
- Hydraulic Cylinders
- Truck and Automotive Parts
- Heavy Equipment
- Agricultural Components
- Auto and Truck Axles, Suspension Parts, Shock Absorbers
- High-Speed Shafts and Rollers
- Bearings, Spacers, Roll Cages, and Other Machined Tubular Parts
