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
The primary purpose of a temper mill is to improve the surface finish on steel products. Components. A typical type of temper mill installation includes entry equipment for staging and accepting hot rolled coils of steel which have been hot wound at the end of a hot strip mill or hot rolled plate mill.
Hot rolled parts are usually dark and dull, their surface oxidized from being hot worked. Extruded products may have die marks running the length of the stock. Other mill finishes are surprisingly smooth and uniform. It is possible for a mill to influence the finish of produced stock.

The decision to express the rawness of hot-rolled mill scale as a finish then placed special emphasis on finding a clear top-coat that would preserve the desired finish and be durable in the field.
This finish is known as No. 1, or HRAP or S&D (for softened and descaled). Hot rolled coils are also treated to produce this finish before being cold rolled and small amounts of five and six-millimetre-thick material are used in this condition, where smoothness of finish is not important.
