S45C steel hollow bushing heat treatment HRC45-55 with smooth surface

S45C steel hollow bushing heat treatment HRC45-55 with smooth surface.

Description

The bushing is a matching part used outside the mechanical parts to achieve the functions of sealing, wear protection, etc. It refers to the ring sleeve that functions as a gasket. In the field of valve applications, the bushing is inside the valve cover, and corrosion-resistant materials such as polytetrafluoroethylene or graphite are generally used for sealing.

Features are:
1. Low frictional resistance: The steel ball can perform stable linear motion with extremely small frictional resistance due to the correct orientation of the retainer.
2. Stainless steel: stainless steel series are also available, suitable for applications requiring corrosion resistance.
3. Exquisite design: extremely small in size and can be designed in exquisite mechanical equipment.
4. Abundant changes: In addition to the standard type, there are also a series of high-rigidity long type, which can be selected according to the purpose.

Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other machining processes, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but by changing the microstructure inside the workpiece or changing the chemical composition of the surface of the workpiece , To give or improve the performance of the workpiece. Its characteristic is to improve the internal quality of the workpiece, which is generally not visible to the naked eye. In order to make the metal workpiece have the required mechanical properties, physical properties and chemical properties, in addition to the reasonable selection of materials and various forming processes, heat treatment processes are often indispensable. Steel is the most widely used material in the machinery industry. The microstructure of steel is complex and can be controlled by heat treatment. Therefore, the heat treatment of steel is the main content of metal heat treatment.
