What is ST52.3 honed tube?
St 52.3 honed tube is the honed tube made of material steel grade st52.3.
In various industries, honed tube is commonly referred to as a hydraulic cylinder tube. One of the reasons for this is that the honed tube is already suitable for use in hydraulic cylinder applications without any additional processing of the ID. Additionally, it is the primary material used in the production of hydraulic cylinders. Because the inside diameter of this type of tubing is usually honed, it is also known as honed ID tubing.
For almost three decades, our factory GUANGXI HYDRAULICS has been producing and supplying honed tube and hydraulic cylinder tubes. Below are the specifications for our honed tube product.

ADVANTAGES OF skyline’s HONED TUBE
- High precision tolerances;
Our honed tube can meet ID tolerance H7, H8, H9, … etc according to the customer’ requirements, and its I.D dimension. - Seamless tube with high pressure resistance;
We only use seamless cold drawn tubes to produce honed pipes, which means our honed tubing can work under higher pressure, thus our honed pipes are more reliable for hydraulic cylinder applications. - High Smooth inside surface;
The roughness of our honed pipe is Max Ra 0.4 microns ID finish (16Max Ra ID Finish). - Flexible order quantity: we accept small quantity orders, even if there is only one piece of hydraulic cylinder tubing we can produce and supply.
- Good weldability: The weldability of our honed steel tubing is very good, this is quite helpful for manufacturing the cylinders.
- Our factory offers a 100% quality assurance guarantee and boast a high customer repurchase rate. We provide honed tubes in both metric sizes and imperial sizes (inch sizes), and customized sizes to meet all our customers’ needs.
