Roughness test

A roughness test for stainless steel works assesses the smoothness of the surface to ensure it meets specified standards. The process involves using a profilometer or roughness gauge, which measures surface texture by scanning across the metal. Parameters such as Ra (average roughness), Rz (mean roughness depth), and Rt (total height of the profile) are recorded. The measured values are compared to the required specifications to confirm whether the surface is adequately finished for its intended application. This testing is crucial for ensuring that stainless steel components have the desired aesthetic quality, functionality, and performance, particularly in precision and sanitary applications.
