Know Your Stainless Steel Finishes Ryerson

Let’s review two of the more common mill finishes: • 2B: This is achieved by cold rolling, heat treating and pickling, along with the application of a light rolling at the end in order to achieve a smooth and reflective sheen. Considered the most widely used surface finish, 2B is the basis for most polished and brushed finishes.
