Web5 ROUGHNESS MEASUREMENTS OF STAINLESS STEEL SURFACES Summary Although Ra values are commonly used to describe surfaces, the limits of this indicator should not be forgotten. Also the notation is important: “Ra ≤ 0.5 µm”, for instance, does not have the same meaning as “Ra max 0.5 µm”.Surface designations such as “2B” Web- The mean arithmetical value “Ra” in μm is assumed for roughness measurements. -Rt: maximum value of roughness from the lowest to the highest point. -Rz: average roug hness in 10 p oints.

WebAug 4, 2024 · Ra-Roughness Average. Ra (roughness average), also called the centerline average, is the arithmetic average of all surface heights measured over a surface. It is one of the most commonly used parameters for measuring surface finish. On the other hand, different surface roughness profiles might have the same Ra yet behave differently. WebThe handheld roughness meter PCE-RT1200 operates according to the touching method compliant with ISO 3274. It is a tactile method, in which the probe tip (diamond) of the handheld roughness meter is pulled at a steady speed over the surface of a workpiece in a horizontal direction. The horizontal displacement of the probe tip simultaneously ...
