Honed tube is the key important material for manufacturing or repairing hydraulic cylinders. As the honed tube is used as hydraulic cylinder barrel, so the strength of the honed tube directly determines how high pressure the hydraulic cylinder can bear.

Why heat treatment is important for st 52.3 honed tube?
ST 52.3 is a high-strength low-alloy steel that is commonly used in the manufacturing of hydraulic cylinders, among other applications. Honed tubes made from ST 52.3 steel are often used in hydraulic systems because of their high resistance to wear and tear, as well as their excellent machining and welding properties.
Heat treatment is necessary for ST 52.3 honed tubes in order to improve their mechanical properties and make them more suitable for their intended application. The heat treatment process involves heating the steel to a specific temperature and then cooling it down slowly, which can result in changes in its microstructure and properties.
The specific type of heat treatment used for ST 52.3 honed tubes may depend on several factors, such as the desired hardness, strength, and toughness of the material. Generally, heat treatment can help to increase the hardness and strength of the steel, which can improve its resistance to wear and deformation under stress.
In summary, heat treatment is necessary for ST 52.3 honed tubes in order to improve their mechanical properties and make them more suitable for use in hydraulic systems and other applications.
What is the heat treatment process of ST52.3 honed tubes?
The heat treatment process for ST52.3 honed tubes typically involves two main types: normalization and stress relief annealing.
Normalization: The first type of the heat treatment process is normalization, which involves heating the honed tubes to a temperature between 850°C and 950°C and holding them at this temperature for a specified period of time. This process is used to refine the grain structure of the material and improve its mechanical properties.
Stress relief annealing: The second type of the heat treatment process is stress relief annealing, which involves heating the honed tubes to a temperature between 550°C and 650°C and holding them at this temperature for a specified period of time. This process is used to reduce residual stresses in the material and improve its dimensional stability.
