Stainless Steel Coil Sheet
Finish | Characteristics | Applications |
---|---|---|
No. 1 | This finish, produced by hot-rolling, annealing and pickling, is characterized by its white pickled surfaces. Sheets and plates with this finish are generally used in industrial applications. | Industrial tanks, Chemical industry equipment. |
No. 2D | A dull cold rolled finish produced by cold rolling annealing and pickling. Sheets with this finish possesses excellent drawability in addition to a dense surface. | General uses for deep drawing. |
No. 2B | This finish is produced by final light cold-rolling (skin pass line), consequently it has a brighter surface and is slightly harder than No. 2 finish. | General application. |
No. 3 | An intermediate polished finish (100-120 mesh), used where a surface is required for post-production treatment. | Kitchen ware, Interior-Exterior decoration for building. |
No. 4 | The most popular of all polished finishes. Produced with abrasives of approximately 150-180 mesh in its finial stage. This finish is widely used where ease in cleaning, an attractive appearnce and high corrosion resistance are required. | Food-processing facilities, Bath-tub. |
No. 8 | The finish is produced with abrasives of over 800 mesh. | Reflector, Mirror, Interior-Exterior decoration for building. |
BA (Bright Annealed) | This finish retains the luster produced by cold-rolling and annealing in a non-oxidizing atmosphere. | Used in an excellent finish is required like automobile trim and reflectors, architectural purposes. |
HL (Hair Line) | This finish is obtained by continuous linear polishing. It produces a soft finish which is effective in dissipating glare. | Most Suitable for architectural purpose, vehicles, show cases, etc. |
