FINISHESX1.1 ScopeThis appendix lists
14、the finishes in whichplate, sheet, and strip are normally supplied. These are subjectto change and the manufacturer should be consulted for thelatest information available.X1.2 SheetThe various types of finish procurable onsheet products are:X1.2.1 No. 1 FinishHot-rolled, annealed, and descaled.X1.2
15、.2 No. 2D FinishDull, cold-rolled finish.X1.2.3 No. 2B FinishBright, cold-rolled finish.X1.2.3.1 Bright-Annealed FinishA bright cold-rolled fin-ish retained by final annealing in a controlled atmospherefurnace.NOTE X1.1Explanation of Finish:No. 1Produced on hand sheet mills by hot rolling to specifi
16、edthicknesses followed by annealing and descaling. Generally used inindustrial applications, such as for heat or corrosion resistance, wheresmoothness and uniformity of finish is not of particular importance.No. 2DProduced on either hand sheet mills or continuous mills bycold rolling to the specifie
17、d thickness, annealing, and descaling. The dullfinish may result from the descaling or pickling operation or may bedeveloped by a final light cold-rolled pass on dull rolls. The dull finish isfavorable for the retention of lubricants on the surface in deep drawingoperations. This finish is generally
18、 used in forming deep drawn articleswhich may be polished after fabrication.No. 2BCommonly produced the same as No. 2D, except that theannealed and descaled sheet receives a final light cold-rolled pass onpolished rolls. This is a general purpose cold-rolled finish. It is commonlyused for all but ex
19、ceptionally difficult deep drawing application. Thisfinish is more readily polished than No. 1 or No. 2D finish.Bright-Annealed FinishA bright cold-rolled highly reflective finishretained by final annealing in a controlled atmosphere furnace. Thepurpose of the atmosphere is to prevent scaling or oxi
20、dation duringannealing. The atmosphere is usually comprised of either dry hydrogen ora mixture of dry hydrogen and dry nitrogen (sometimes known asdissociated ammonia).X1.3 StripThe various types of finish procurable oncold-rolled strip products shall be as follows:X1.3.1 No. 1 FinishCold-rolled to
21、specified thickness,annealed, and pickled.X1.3.2 No. 2 FinishSame as No. 1 finish, followed by afinal light cold-rolled pass, generally on highly-polished rolls.X1.3.3 Bright-Annealed FinishA bright cold-rolled finishretained by final annealing in a controlled atmosphere furnace.NOTE X1.2Explanation
22、 of Finish:No. 1Appearance may be dull-gray matte to fairly reflective. Thisfinish is used for severely drawn or formed parts as well as for applicationswhere the brighter No. 2 finish is not required, such as in parts for heatresistance.No. 2This finish has a smoother and more reflective surface. T
23、his isa general purpose finish, widely used for household and automotive trim,tableware, utensils, trays, etc.Bright-Annealed FinishA bright cold-rolled highly reflective finishretained by final annealing in a controlled atmosphere furnace. Thepurpose of the atmosphere is to prevent scaling or oxida
24、tion duringannealing. The atmosphere is usually comprised of either dry hydrogen ora mixture of dry hydrogen and dry nitrogen (sometimes known asdissociated ammonia).X1.3.4 The various types of edges obtainable on strip are asfollows:X1.3.5 No. 1 EdgeRolled edge, either round or square asspecified.X
25、1.3.6 No. 3 EdgeAn edge produced by slitting.X1.3.7 No. 5 EdgeApproximately square edge producedby rolling or filing after slitting.X1.4 PlateThe types of finish obtainable on plate are asfollows:X1.4.1 Hot-Rolled, AnnealedScale not removed. Use ofplates in this condition is generally confined to he
26、at-resistingapplications.X1.4.2 Hot-Rolled, Annealed, DescaledScale removed bya blast-cleaning or pickling operation. Finish commonly pre-ferred for corrosion resisting applications or where non-fluxtype welding operations will be performed.X1.4.3 Cold-Rolled, AnnealedBright-annealed finish orscale
