Roughness measurements of stainless steel surfaces.
Stainless steel is polished by mills in a range of forms, e.g. sheet, plate, bar & tube, but all finishes may not be available on all forms. It is important, therefore, to check that the finish is available in the form required. Hot rolled, softened (annealed) with the surface de-scaled.
Some of these originate from the mill but many are applied later during processing, for example polished, brushed, blasted, etched and coloured finishes. The importance of surface finish in determining the corrosion resistance of the stainless steel surface cannot be overemphasised.

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
Nov 24, 2015 · The most common stainless steel finish is 2B. This method is cold rolled, heat-treated, pickled and pinch-passed, resulting a slightly reflective surface similar to a cloudy mirror. The 2B mill finish is achieved with an additional light cold roll pass, and is the standard finish for 201, 301, 304, 304L, and 316L stainless steel.Author Forthgear Site Admin
stainless steel tubing surface finish There are 3 surface finishes that are well known in the industry Bright Annealed, Polished and Annealed and Pickled. The Bright Annealed stainless steel tubing, commonly referred to as BA finish, is cold rolled using highly polished rolls in contact with the steel surface, making it both smooth and bright.

May 08, 2007 · High Expectations. Stainless steel tubular parts, such as handlebars, subway grab bars, and hand railings, are installed in high-visibility areas, so the tube's OD needs to exhibit a smooth, blemish-free appearance. One big challenge in stainless steel manufacturing and finishing is the growing expectation for the surface finish, said Tom Carroll,...
The Standard Mill Surface Finished are laid down in Specifications (BS 1449, Part 4, and the Committee of Stainless Steel Producers, American Iron & Steel Institute). The finished are designated by a system of numbers, and these are broadly described hereunder relative to the finishing operations employed.
Manufacture of Stainless Steel Flat Products. The most reflective mill finish is achieved by Bright Annealing in a reducing dry nitrogen/hydrogen atmosphere - BA finish. The smooth surface developed by cold rolling is retained by the annealing atmosphere which prevents oxidation of the surface.
TUBE & PIPE. As-welded tube and pipe are produced by forming mill finished 2B sheet, strip or plate into the desired shape, welding the seam, and then cleaning the welds to restore corrosion resistance. This finish is specified for applications where corrosion resistance is …
Jul 07, 2014 · Standard mill finishes usually are applied to flat-rolled stainless steel directly by the manufacturer. The fabricator then applies a final finish to the welded surface to achieve the desired aesthetic appearance. Some of the most commonly used final finishes are #3 — Coarse abrasive finish applied mechanically. #4 — Brushed finish.
The smoother the surface finish is, the higher resistance to corrosion it will be. These mill produced finishes must be handled carefully as surface damage such as scratches, grinding marks or spatter cannot be matched by polishing with abrasives or etching with chemicals. Of the 3 finishes, BA is most nearly able to be matched by a mirror polish.
