BA (Bright Annealed) or 2R stainless steel is a specific surface finish produced by cold-rolled stainless steel mills, mainly for AISI 304 and AISI 316 grades and in thicknesses up to a maximum of 3.0 mm. During its production, the stainless steel is annealed in an inert gas atmosphere after cold rolling, which produces a reflective, shiny, and smooth surface texture.
