2B stainless steel is a very common mill finish supplied by steel stockholders. It should be supplied cold rolled, softened and de-scaled. There is then a final 'pinch pass' finishing process through polishing rollers. This process is designed to give the surface a bright semi-reflective surface. Note: it is not mirror polished. The surface remains a semi-bright grey in colour.
2B Pattern Finished is a bright cold rolled finish commonly produced in the same manner as No. 2D, except that the final light cold rolling pass is done using polished rolls. This produces a more reflective finish that resembles a cloudy mirror. Finish reflectivity can vary from manufacturer-to-manufacturer and coil-to-coil with some coils looking quite mirror-like and others being fairly dull. No. 2B is a general purpose cold rolled finish commonly used for all but exceptionally difficult deep drawing applications. It is more readily polished to high luster than a No. 1 or No. 2D finish.
