Stainless steel surface roughness

The classification of rolled surfaces and polished surfaces is an indication of the degree to which they can be achieved. Another effective representation is the measurement of surface roughness. The standard method of measurement, known as CLA (center line average), is to move the gauge across the surface of the steel plate and record the magnitude of the change in peak-to-valley. The smaller the CLA number, the smoother the surface. The final results for different grades can be seen from the surface processing and CLA numbers in the table below.
