Materials

Stainless steel 2b finish is a basics surface for any further cold-rolled processing. It is a smooth, and slightly reflective surface.

The BA finish has a mirror-like surface but is less reflective than an 8K mirror finish because its surface has cloudiness and other imperfections.

The surface of hot-rolled stainless steel comes in 5 grades. No.1 is the primary surface finish, which results from hot rolling to the specified thickness, followed by annealing and descaling. With sheets/coils/strips types, No. 1 finish stainless steel is characterized by its rough, dull, and non-uniform appearance. It is generally used in industrial applications where the surface finish is not critical, such as chemical tanks, piping, heat exchangers, equipment for elevated temperature service, and checker plates.
