(Summary description)Heat treatment usually does not change the shape and overall chemical composition of the workpiece, but by changing the internal microstructure of the workpiece or changing the chemical composition of the surface of the workpiece, thereby imparting or improving the performance of the workpiece, which is characterized by improving the internal quality of the workpiece. It is invisible to the naked eye.

Do you know the reasons for heat treatment of flanges? Let’s follow the editor of WN Flange for a simple understanding!
Heat treatment usually does not change the shape and overall chemical composition of the workpiece, but by changing the internal microstructure of the workpiece or changing the chemical composition of the surface of the workpiece, thereby imparting or improving the performance of the workpiece, which is characterized by improving the internal quality of the workpiece. It is invisible to the naked eye.
The role of heat treatment is to improve the mechanical properties of the material, eliminate residual stress and improve the workability of the metal. According to the different purposes of heat treatment, the heat treatment process can be divided into two categories: preliminary heat treatment and final heat treatment. Let's first understand the knowledge of pre-heat treatment!
The purpose of preliminary heat treatment is to improve processing performance, eliminate internal stress and prepare a good metallurgical structure for final heat treatment. The heat treatment process includes annealing, normalizing, aging, quenching and tempering.
Annealing and normalizing are used to hot work the blanks. For carbon steel and alloy steel with a carbon content greater than 0.5%, annealing treatment is usually used to reduce its hardness and make it easier to cut. For carbon steel and alloy steel with a carbon content of less than 0.5%, normalizing treatment is used to prevent cutting edge adhesion during low-hardness cutting. Annealing and normalizing are usually arranged after the blank is manufactured and before roughing. It can refine the grain and uniform structure and prepare for future heat treatment.
The aging treatment is mainly used to eliminate the internal stress caused by rough machining and machining. In order to avoid excessive transportation workload, aging treatment can be arranged before processing parts with general accuracy. However, two or more aging treatments should be arranged for the parts. Simple parts usually do not age.
In addition to castings, for some rigid parts, in order to eliminate the internal stress generated during the machining process and stabilize the machining accuracy of the parts, some shaft parts are also processed, and aging treatment after straightening is also required.
Quenching and tempering are high temperature tempering treatments after quenching. A uniform and fine tempered sorbite structure can be obtained, which can be used to reduce the deformation during surface quenching and nitriding treatment. Therefore, quenching and tempering can also be used as a preliminary heat treatment. Because the parts have better comprehensive mechanical properties after quenching and tempering, some parts that do not require high hardness and wear resistance can also be used as the final heat treatment process.
The above is the WN Flange editor's description: the knowledge of flange heat treatment, I hope you can learn more.
