Stainless steel plates are divided into hot rolling and cold rolling according to the different rolling processes of the rolling mill (the rolling mill is the name of the machine for rolling plates). People will label hot rolling as NO.1 and cold rolling as 2B or BA. Compared with 2B, the advantage of BA is that the surface is smoother and brighter. The surface effect of BA should be close to the mirror effect, and the best one is the mirror surface.
