a maximum, Ra tolerance for the surface finish. The surface in question, seal on an 'o' ring, to prevent fluid leakage. Is there any reason why I would not want less than the minimum Ra (0.2 in this case)?
The surface finish of stainless steel impacts more than aesthetics as performance, reliability, and other important factors also come into play.Regardless of the application or end-use of the stainless steel, the surface finish should be selected to best meet the requirements at hand. This is ...
What is PCB OSP? OSP surface finish is an organic applied on a bare copper circuit board. Organic Solderability Preservative is an anti-tarnish surface finish whose primary function is to prevent the printed circuit boards' copper layer from oxidation. OSPs are a water-based chemical compound tha...
Letter 9842,"Ra surface finish vs. grit conversion chart", suggests that a USA grit size of 240 is equivalent to an Ra of about 0.45 µm, while a UK grit size of 240 is equivalent to an Ra of about 1.5 µm. But with this as background, I think you'd better ask your custome...

● Glass cleanercan leave streaks on the stainless steel finish. Harsher chemicals (benzene, thinner, bleach, alcohol, acetone, ammonia) can erode the protective coating that is applied to the surface and could cause an electric shock.

Ra – surface finish value in micrometers/microinch R1, R2, ...Rn - Peaks along the scanned surface. n - along the scan surface Number of peaks Cl – mean contour height Rz - peak-to-valley average Rz is the second most commonly used unit. Rz is calculated by measuring the vertical...
On one hand, the spatial localization of the sensitive volume is less favorable, but on the other hand, such coils self-cancel far-field electromag- netic noise. Given that B0 of the original NMR-MOUSE is parallel to its surface, the degree of macroscopic order of oriented matter like ...
