ASTM A480/A 480M-08bNo. 2DCold-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. 2BCold-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 AnnealedA 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. 3Intermediate 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. 4General 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.6Dull 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. 7High 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 .
