The heat treatment of the honed tube is a very important process. After heat treatment, it can obtain better performance.
Let’s introduce the heat treatment process of honing tubes, including the following steps: forging annealing, rough machining, quenching and tempering, semi-finishing, stress relief, rough grinding, high-frequency quenching, tempering, and finishing.
The following focuses on two key aspects:
1. Quenching and tempering: The purpose of quenching and tempering is to make the honed tubes have good comprehensive mechanical properties. Therefore, in order to obtain high hardness, corresponding strength and excellent mechanical properties, we generally need to carry out tempering treatment for honed tubes of material SAE 1020, CK45 and SAE 4140 honed tubes.
2. Stress relief treatment: Under normal circumstances, annealed castings, forgings, and weldments generate internal stress due to the different cooling rates of each part during cooling, so stress relief treatment is required for honed tubing.
Our factory is one of the high quality honed tube suppliers in China. We manufacture and supply full range of metric size and imperial sizes of hydraulic cylinder honed tubes (hydraulic cylinder barrel), with various materials upon customers requirements. Customers who want to buy honed tubes/ hydraulic cylinder barrels, please feel free to contact us.
Besides hydraulic cylinder barrel, we also produce below products and materials for hydraulic cylinder applications.
- Hard Chrome plated rods for hydraulic cylinder & penumatic cylinder applications
- Hard chrome plated hollow rods for hydraulic cylinder & penumatic cylinder applications
Not only the honed tubes need to be performed with suitable heat treament, the chrome plated rods and chrome plated hollow rods also need to be heat treated with suitable heat treatment process. The heat treatment process is determined by the material steel grade itself and the purpose the user want to achieve.
Our products are widely used for hydraulic cylinder manufacturing and repairing. Our factory is professional in the filed of hydraulic cylinders and penumatic cylinders.
