  • Surface Roughness vs Surface Finish

    Jul 14, 2021Jul 14, 2021The term "Finish" is used to describe the appearance of a stainless plate or sheet and can be highly subjective. Surface Roughness is objectively measured with calibrated equipment. Stainless steel with a 2B mill finish is a bright, relatively defect-free finish produced by a final cold roll pass using polished rollers.

  • Stainless Steel Roughness and Ra

    Why is surface roughness important? Smooth stainless steel surfaces, free from crevices and pits, help prevent entrapment areas where product and microorganisms can build up. This is important for equipment used in sanitary processes such as food and beverage (including dairy), pharmaceutical, biotech, cosmetics, and some chemical production.

    5 ROUGHNESS MEASUREMENTS OF STAINLESS STEEL SURFACES Summary Although Ra values are commonly used to describe surfaces, the limits of this indicator should not be forgotten. Also the notation is important: "Ra ≤ 0.5 m", for instance, does not have the same meaning as "Ra max 0.5 m".Surface designations such as "2B"

  • Surface roughness of common materials

    The roughness is actually a measurement of all the asperities at the surface of a material, especially a pipe where it will oppose the flow of fluid. The following table is summarizing usual pipe roughness for many materials used for piping or ducts. For steel pipes, when nothing more is precised, 0.05 mm is 1 st good approximation.
