2B Finished

2B finish is the type that had skin-pass (temper-rolling) preformed on #2D, low-reflective finish with no grain or direction. It has better gloss and surface flatness compared to #2D. It’s the standard surface class with improved mechanical properties. This is the normal finish out of the mill applicable for almost all uses. refers to the surface texture (or finish) of metal after it exits a rolling mill, extrusion die, or drawing processes, including sheet, bar, plate, or structural shapes. This texture is usually rough and lacks lustre; it may have spots of oxidation or contamination with mill oil.

No. 2B Finish is a bright cold rolled finish, produced very similarly to the No. 2D finish. The difference in the production lies in the final light cold rolling pass of a No 2B Finish, that is is done using polished rolls. This light cold rolling creates a more reflective finish, similar to a cloudy mirror. Finished reflectivity varies from manufacturer-to-manufacturer and coil-to-coil, with some coils having greater or lesser reflectivity. The No. 2B is a general purpose cold rolled finish and is commonly used for all but exceptionally difficult deep drawing applications. It is more easily polished to high luster than a No. 1 or No. 2D finish.
