What Is The Coefficient Of Friction Of Stainless Steel Rods

The coefficient of friction of stainless steel depends on the lubrication conditions and the type of friction. In the case of lubrication, the rolling friction coefficient is 0.05~0.10, the sliding friction coefficient is 0.15~0.30, and in the case of no lubrication, the rolling friction coefficient is 0.12, and the sliding friction coefficient is 0.30~0.40.

 

The coefficient of friction is the ratio of the frictional force between two surfaces to the perpendicular force acting on one of their surfaces. It is related to the roughness of the surface, not the size of the contact area. According to the nature of the motion, it can be divided into dynamic friction coefficient and static friction coefficient. Sliding friction is produced when two objects come into contact with each other and slide relative to each other. In addition, the coefficient of friction of threaded fasteners is affected by factors such as preload, clamping method, etc. The anti-slip coefficient of the friction surface involves factors such as the pressure of the stressed surface and the characteristics of the material of the friction surface.

 

In practice, the axial preload of the coupling can be effectively controlled by monitoring the friction coefficient to ensure a stable connection. The test results show that the surface roughness, preload, clamping method and other factors will affect the friction coefficient of stainless steel threaded fasteners. In addition, the stainless steel friction surface formed by ordinary steel friction surface treatment processes (such as sandblasting and shot blasting) has a low slip resistance coefficient, while a higher anti-slip coefficient can be obtained by adopting new treatment processes such as wire drawing, mechanical scoring and spraying stainless steel powder
