Roughness measurements of stainless steel surfaces

Roughness measurements of stainless steel surfaces Introduction Ra value Surface roughness is a measure of the texture of a surface. It is quantified by the vertical deviations of a real surface from its ideal form. If these deviations are great, the surface is rough, if they are small, the surface is smooth. Roughness is typically considered to
