Tīmeklis5 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” Tīmeklis光洁度与粗糙度Ra、Rz数值对照换算表 (单位：μm) 图 4 最大高度粗操度 2.
