The electropolishing process may improve a surface finish by up to 50%. The electropolishing reaction removes material while it improves surface roughness. Because of the material removal, process runtimes are often limited to maintain dimensional tolerances. Limited runtimes result in real world surface roughness improvements from 10 to 35%.

Surface Roughness Chart: Understanding Surface Finishes rapiddirect
Surface finish refers to the process of altering a metal''s surface that involves removing, adding, or reshaping. It is a measure of the complete texture of a product''s surface that is defined by three characteristics of surface roughness, waviness, and lay. The surface roughness is the measure of the total spaced irregularities on the surface.
Ra surface finish unitless, or what are the units
A. The average roughness, Ra, is expressed in units of height. In the Imperial (English) system, Ra typically expressed in "millionths" of an inch. This is also referred to as "microinches" or sometimes just as "micro" (however the latter is just slang). In the metric system, Ra is typically expressed as "millionths of a meter" also called ...

Considered the most widely used surface finish, 2B is the basis for most polished and brushed finishes. Such common stainless steel grades as 201, 304, 304L and 316L come in a standard 2B finish. • 2D This finish is also achieved by cold rolling, heat treating and pickling, but, unlike 2B, does not receive the light rolling.

Surface Finish Units From RA To RZ. Ra Average Roughness. Ra is also known as Arithmetic Average (AA) or Center Line Average (CLA). It is the average roughness in the area between the roughness profile and its mean line. Graphically, Ra is the area between the roughness profile and its centerline divided by the evaluation length.
