Nov 24, 2015 · The most common stainless steel finish is 2B. This method is cold rolled, heat-treated, pickled and pinch-passed, resulting a slightly reflective surface similar to a cloudy mirror. The 2B mill finish is achieved with an additional light cold roll pass, and is the standard finish for 201, 301, 304, 304L, and 316L stainless steel.
2B, 2D and BA Cold Rolled Finishes
What Are Cold Rolled finishes?StandardsPost Production Processing to Improve Corrosion ResistanceDifferences Between AlloysCold rolled finishes apply to flat products such as sheet or coil, with thickness less than about 5mm and usually less than 3mm. They are firstly hot rolled into a strip (or cast into a slab which is hot rolled into a strip) and then cold rolled. Cold rolling reduces the thickness by at least 50%. This smooths the surface, refines the grain structure and causes differences in the mechanical properties along and across the rolling direction.
