Buffed finishes. There is currently no provision for specifying buffed finishes on stainless steel flat products in BS EN 10088-2. BS 1449-2 (1983), which was replaced by BS EN 10088-2, was the previous standard for stainless steel flat products and did define two buffed finishes, 3B, dull buffed and 7, bright buffed.

The 2B stainless steel finish is the most common stainless steel finish. This cold roll finish yields a smooth matte surface. It's mostly non-reflective and smooth, with good evenness. Following the cold rolling process, the stainless steel is annealed and pickled. After this, 2B stainless steel is passed through "bright rolls."
