Whether you require standard or custom sizes, our wide selection of diameters and lengths ensures that we can meet your specific requirements with precision and reliability.

Surface:

We place a high emphasis on surface quality, as it plays a critical role in the performance and longevity of steel bars and shafts in various applications. To meet diverse needs and ensure the highest level of precision and smoothness, we offer several surface treatments:

Peeled:

Peeled surfaces involve the removal of the outer layer of the material to eliminate any imperfections such as scales, decarburization, or minor surface defects. This process produces a smooth, clean finish that enhances the material’s appearance and prepares it for further processing. Peeled steel bars and shafts are ideal for applications requiring a high degree of dimensional accuracy and surface integrity.

Polished:

Polished surfaces undergo a series of abrasive processes to achieve a highly smooth and reflective finish. This treatment not only improves the aesthetic appeal but also enhances the material’s resistance to corrosion and wear. Polished steel bars and shafts are commonly used in applications where a superior surface finish is critical, such as in the manufacturing of precision instruments, medical devices, and high-end machinery components.

Turned:

Turned bright surfaces are achieved through precision turning operations that produce a bright, shiny finish with excellent dimensional accuracy. This process removes surface irregularities and provides a uniform, visually appealing appearance. Turned bright steel bars and shafts are particularly suited for applications that demand both high mechanical performance and an attractive finish, including automotive parts, hydraulic systems, and general engineering components.

 

By offering these advanced surface treatments, we ensure that our steel bars and shafts not only meet but exceed the stringent requirements of various industrial applications. Each treatment option is designed to enhance the material’s functionality, durability, and overall performance, making our products the ideal choice for a wide range of demanding environments.

 

Condition:

To ensure our steel bars and shafts deliver optimal performance and durability, we provide them in a specific heat-treated condition known as quenched and tempered. This treatment process significantly enhances the mechanical properties of the steel, making it suitable for a wide range of demanding applications.

Quenched:

Quenching is a meticulous heat treatment process where the steel is heated to a high temperature and then rapidly cooled in water, oil, or another cooling medium. This rapid cooling transforms the microstructure of the steel, increasing its hardness and strength. Quenching helps in achieving the desired mechanical properties, particularly in applications that require high wear resistance and the ability to withstand heavy loads. The process reduces internal stresses and prepares the steel for further tempering to refine its properties.

Tempered:

After quenching, the steel undergoes tempering, a controlled reheating process to a temperature below its critical point, followed by cooling at a slower rate. This step is crucial as it reduces the brittleness induced by quenching and enhances the toughness and ductility of the steel. Tempering allows for the fine-tuning of mechanical properties, striking a balance between hardness and toughness, which is essential for components subjected to dynamic loads and varying operational conditions. The tempering process also improves the steel’s overall stability and resistance to cracking under stress.

 

By providing our steel bars and shafts in a quenched and tempered condition, we ensure that they possess a superior combination of strength, hardness, and toughness. This makes them ideal for high-performance applications such as automotive components, heavy machinery, construction equipment, and critical engineering parts. Our meticulous heat treatment processes guarantee that the materials can withstand extreme conditions and deliver reliable, long-lasting performance in the most demanding industrial environments.

More Services:

In addition to offering high-quality steel bars and shafts, we provide a range of specialized services to enhance the functionality and performance of our products. These additional services are designed to meet specific requirements and improve the overall utility of the materials in various applications.

Chromed:

Our chroming service involves applying a layer of chromium to the surface of the steel bars and shafts through an electroplating process. This treatment provides several key benefits:

– Corrosion Resistance: The chromium layer acts as a protective barrier against oxidation and corrosion, significantly extending the lifespan of the steel in harsh environments.

– Wear Resistance: Chrome plating increases the surface hardness, making the steel more resistant to wear and abrasion, which is critical for components that experience high friction and mechanical stress.

– Aesthetic Appeal: The bright, reflective finish of chrome plating enhances the visual appeal of the steel, making it suitable for applications where appearance matters.

Chromed steel bars and shafts are ideal for use in hydraulic cylinders, automotive parts, and machinery components that require both durability and a high-quality finish.

Borehole:

Our borehole service involves precision drilling of holes into the steel bars and shafts according to specific requirements. This service is essential for creating internal passages and cavities that are critical for various applications:

– Hydraulic Systems: Boreholes allow for the integration of fluid channels in hydraulic cylinders and actuators, facilitating the efficient flow and control of hydraulic fluids.
