Hemaokang Steel (Shandong) Co., Ltd. presents our high-quality Carbon Steel Rod for Hydraulic Cylinder Piston Rod Machining, produced from C45 steel with precision ground and polished surfaces. As a specialized manufacturer located in Liaocheng, Shandong, we focus on delivering round bar stock that meets the demanding requirements of hydraulic cylinder builders and fluid power equipment makers. Our rods are designed to support efficient machining processes while providing a reliable substrate for durability-focused surface treatments.
This C45 carbon steel rod is a versatile choice for piston rod manufacturing, offering a balanced combination of strength, machinability, and surface consistency. The ground and polished finish minimizes initial processing time and helps achieve the close tolerances required in hydraulic applications. Whether you are producing tie-rod cylinders, welded cylinders, or telescopic cylinders, this product is intended to be a dependable starting point for your machining line.
Key Product Features
- Made of C45 carbon steel, known for good hardness and wear resistance after proper heat treatment.
- Surface is ground and polished to a smooth finish, reducing the need for extensive pre-machining.
- Suitable for further processing such as turning, threading, and induction hardening.
- Optional hard chrome plating can be applied to enhance corrosion resistance and surface hardness.
- Straightness and dimensional tolerances are controlled for consistent performance in hydraulic cylinder assemblies.
- Custom lengths and diameters are available upon request to match your specific production needs.
Material and Machining Benefits
C45 is a medium carbon steel widely used in mechanical engineering and hydraulic component manufacturing. Its carbon content provides a good balance of strength and ductility, making it suitable for piston rods that experience cyclic loads. The material can be heat treated to improve core hardness while maintaining a machinable structure. For the end user, this translates into components that resist bending, deformation, and premature wear under normal operating conditions.
The ground and polished surface of our rods offers a practical advantage: it reduces surface roughness and eliminates scale, pits, and other irregularities that can affect seal performance. A smoother rod surface helps extend the life of hydraulic seals and wipers, reduces friction, and contributes to more stable system operation. This is especially important in high-cycle hydraulic cylinders where leakage and seal failure are major concerns.
Processing Flexibility
Our carbon steel rods can be supplied in various condition stages, depending on your production process. You may order the rods in the as-ground and polished state for immediate machining, or request additional options such as centerless grinding, chamfering, threading, and drilling. This flexibility allows you to integrate the rod into your existing production line without unnecessary handling or additional setup time.
