ASTM A480/A 480M-08b | No. 2D | Cold-rolled , dull finish ; | A smooth , nonreflective cold-rolled annealed and pickled or descaled finish . This nondiredtional finish is favorable for retention of lubricants in deep drawing applications . |
No. 2B | Cold-rolled , bright finish ; | A smooth , moderately reflective cold-rolled annealed and pickled or descaled finish typically produced by imparting a final light cold-rolled pass using polished rolls . This general-purpose finish is more readily polished than No.1 or 2D finishes . |
Bright Annealed | A bright cold-rolled finish retained by final annealing in a controlled atmosphere furnace . | A smooth , bright , reflective finish typically produced by cold rolling followed by annealing in a protective astmosphere so as to prevent osidation and scaling during annealing . |
No. 3 | Intermediate polished finish , one or both sides . | A linearly textured finish that may be produced by either mechanical polishing or rolling . Average surface roughness ( Ra) may generally be up to 40 micro-inches . ...... |
No. 4 | General purpose polished finish , one or both sides . | A linearly textured finish that may be produced by either mechanical polishing or rolling . Average surface roughness ( Ra) may generally be up to 25 micro-inches . ...... |
No.6 | Dull stain finish , Tampico Brushed , one or both sides . | This finish has a soft , satin appearance typically produced by tampico brushing a No.4 finish . |
No. 7 | High luster finish . | Has a high degree of reflectivity . |
No. 8 | Mirror finish . | This is a highly reflective , smooth finish typically produced by polishing with successively finer grit abrasives . Then buffing . |
TR | Cold-worked to obtain specified properties . | The finish resulting from the cold-rolling of an annealed and descaled or bright annealed product to obtain mechanical properties higher tahn that of the annealed condition . |

2D | Cold rolled , heat treated , pickled or descaled . | The surface is uniform and matte . |
2B | Cold rolled , heat treated , pickled or descaled , skin passed . | Smoother and straighter than 2D surface . |
BA | Cold rolled , bright annealed . | Smooth, shiny and reflective . |
3# | Brushed or matte finished on one or both sides . | No reverse texture, no reflection . |
4# | Apply universal polished to one or both sides . | No directional texture , reflective . |
6# | Single side or double side matte satin finish polished , tan leather research mill . | Matte and no directional texture . |
7# | High gloss surface finished . | Smooth, high reflectance . |
8# | 8K super mirror finished . | Directionless texture, high reflectance, clear image . |
TR | Cold hardened treatment . | Should be changed according the material and the cold amount . |
HL | Cold rolled, pickled, leveled, grinded . | Continuous grinding pattern . |
