Do ordinary steel, stainless steel have the same friction coefficient as other materials? If they are different, are they different?
If ordinary steel and stainless steel are machined to the same surface roughness, they have the same coefficient of friction on the surface of the same object.
The coefficient of friction is the ratio of the force of friction between two surfaces to the vertical force acting on one surface. It is only concerned with the surface roughness of the object.
