PART A—FERROUS MATERIAL SPECIFICATIONS SA-480/SA-480M
5.1.1The steel shall be made by one of the following processes:electric-arc,electric-induction,or other suitable processes.
5.1.2If a speci?c type of melting is required by the purchaser,it shall be so speci?ed on the purchase order.
6.Heat Analysis
6.1An analysis of each heat shall be made by
the steel producer to determine the percentages of the elements speci?ed in the applicable material speci?ca-tion.This analysis shall be made from a test sample taken during the pouring of the melt,or from the in-process product later in the manufacturing?ow.The chemical composition thus determined shall conform
to the applicable material speci?cation.
6.2Methods and practices relating to chemical analysis shall be in accordance with Test Methods, Practices,and Terminology A751.
6.3The steel shall not contain an unspeci?ed element for the ordered grade to the extent that the steel conforms to the requirements of another grade
for which that element is a speci?ed element having
a required minimum content.For this requirement,a grade is de?ned as an alloy described individually and identi?ed by its own UNS designation in a table of chemical requirements within this speci?cation or any speci?cation listed within the scope as being covered

a particular element in a single sample for product analysis may be either above or below the speci?ed range.However,percentages must exhibit the same tendencies in all samples;that is,the several determina-tions of any individual element in a heat may not vary both above and below the speci?ed range.
8578.Finish for Sheet
8.1The types of?nish available on sheet products are:
8.1.1No.1Finish—Hot-rolled,annealed,and descaled.
8.2.1No.2D Finish—Cold-rolled,dull?nish.
8.1.3No.2B Finish—Cold-rolled,bright?nish.
8.1.3.1Bright Annealed Finish—A bright cold-rolled?nish retained by?nal annealing in a controlled atmosphere furnace.
8.1.4No.3Finish—Intermediate polished?nish, one or both sides.
8.1.5No.4Finish—General purpose polished ?nish,one or both sides.
8.1.6No.6Finish—Dull satin?nish,Tampico brushed,one or both sides.
8.1.7No.7Finish—High luster?nish.
8.1.8No.8Finish—Mirror?nish.
8.1.9TR Finish—Cold-worked to obtain speci?ed properties.
NOTE2—Explanation of Sheet Finishes:
No.1—This?nish is produced by hot rolling to speci?ed thickness followed by annealing and descaling.It is generally used in industrial applications,such as for heat and corrosion resistance,where smooth-ness of?nished is not of particular importance.
No.2D—Produced on either hand sheet mills or continuous mills by cold rolling to speci?ed thickness,annealing,and descaling.The dull?nish may result from the descaling or pickling operation or may be developed by a?nal light cold-rolled pass on dull rolls. The dull?nish is favorable for retention of lubricants on the surface in deep drawing operations.This?nish is generally used in forming deep-drawn articles which may be polished after fabrication.
No.2B—Commonly produced the same as2D,except that the annealed and descaled sheet receives a?nal light cold-rolled pass on polished rolls.This is a general purpose cold-rolled?nish.It is commonly used for all but exceptionally dif?cult deep drawing applications.This?nish is more readily polished than No.1or No. 2D Finish.
Bright Annealed Finish is a bright cold-rolled highly re?ective?nish retained by?nal annealing in a controlled atmosphere furnace.The purpose of the atmosphere is to prevent scaling or oxidation during annealing.The atmosphere is usually comprised of either dry hydrogen or a mixture of dry hydrogen and dry nitrogen(sometimes known as dissociated ammonia).
No.3—For use as a?nish-polished surface or as a semi?nished-polished surface when it is required to receive subsequent?nishing operations following fabrication.Where sheet or articles made from it will not be subjected to additional?nishing or polishing operations, No.4?nish is recommended.
SA-480/SA-480M1998SECTION II
No.4—Widely used for restaurant equipment,kitchen equipment, store fronts,dairy equipment,etc.Following initial grinding with coarser abrasives,sheets are generally?nished last with abrasives approximately120to150grit.
No.6—Has a lower re?ectivity than No.4?nish.It is produced
by Tampico brushing No.4?nish sheets in a medium of abrasive
and oil.It is used for architectural applications and ornamentation where high luster is undesirable;it is also used effectively to contrast
with brighter?nishes.
No.7—Has a high degree of re?ectivity.It is produced by buf?ng
a?nely ground surface,but the grit lines are not removed.It is
chie?y used for architectural or ornamental purposes.
No.8—The most re?ective?nish that is commonly produced.It
is obtained by polishing with successively?ner abrasives and buf?ng extensively with very?ne buf?ng rouges.The surface is essentially
free of grit lines from preliminary grinding operations.This?nish
is most widely used for press plate,as well as for small mirrors
and re?ectors.
TR Finish—The?nish of products resulting from cold-working an annealed and descaled or bright-annealed product suf?ciently to obtain mechanical properties higher than that normally obtained. Appearance will vary depending upon the amount of cold work required and the alloy ordered.
8.1.10Sheets can be produced with one or two sides polished.When polished on one side only,the other side may be rough ground in order to obtain the necessary?atness.
9.Finish for Strip
9.1The various types of?nish procurable on cold-rolled strip products are:
9.1.1No.1Finish—Cold-rolled to speci?ed thickness,annealed,and descaled.
9.1.2No.2Finish—Same as No.1Finish, followed by a?nal light cold-roll pass,generally on highly polished rolls.
9.1.3Bright Annealed Finish—A bright cold-rolled?nish retained by?nal annealing in a controlled atmosphere furnace.
9.1.4TR Finish—Cold-worked to obtain speci?ed properties.
9.1.5Polished Finish—Stainless steel strip is also available in polished?nishes such as No.3and No.4,which are explained in Note2.
NOTE3—Explanation of Strip Finishes:
No.1—Appearance of this?nish varies from dull gray matte?nish
to a fairly re?ective surface,depending largely upon composition. This?nish is used for severely drawn or formed parts,as well as
for applications where the brighter No.2Finish is not required, such as parts for heat resistance.
858No.2—This?nish has a smoother and more re?ective surface, the appearance of which varies with composition.This is a general purpose?nish,widely used for household and automotive trim, tableware,utensils,trays,etc.
Bright Annealed Finish—See Note2.
TR Finish—See Note2.
10.Finish for Plates
10.1The types of?nish available on plates are:
10.1.1Hot-Rolled or Cold-Rolled,and Annealed or Heat Treated—Scale not removed,an intermediate ?https://www.doczj.com/doc/2e19231750.html,e of plates in this condition is generally con?ned to heat-resisting applications.Scale impairs corrosion resistance.
10.1.2Hot-Rolled or Cold Rolled,and Annealed or Heat Treated,and Blast Cleaned or Pickled—Condition and?nish commonly preferred for corrosion-resisting and most heat-resisting applications,essentially
a No.1Finish.
10.1.3Hot-Rolled or Cold-Rolled,and Annealed or Heat Treated,and Surface Cleaned and Polished—Polish?nish is generally No.4Finish.
10.1.4Hot-Rolled or Cold-Rolled,and Annealed or Heat Treated,and Descaled,and Temper Passed—Smoother?nish for specialized applications.
10.1.5Hot-Rolled or Cold-Rolled,and Annealed or Heat Treated,and Descaled;and Cold-Rolled,and Annealed or Heat Treated,and Descaled,and Option-ally Temper Passed—Smooth?nish with greater freedom from surface imperfections than in10.1.4. 11.Edges for Cold-Rolled Strip
11.1The types of edges available on strip prod-ucts are:
11.1.1No.1Edge—A rolled edge,either round or square as speci?ed.
11.1.2No.3Edge—An edge produced by slitting.
11.1.3No.5Edge—An approximately square edge produced by rolling or?ling after slitting. 12.Heat Treatment
12.1The heat treatments shown in Table A1.2and described in this section are to be followed unless otherwise speci?ed in the applicable material speci?ca-
PART A—FERROUS MATERIAL SPECIFICATIONS SA-480/SA-480M
tion.Heat treatment thermal cycles shall be separate from other processing cycles.
12.2Austenitic Types:
12.2.1The material shall be solution annealed
to meet the mechanical property requirements of the applicable material speci?cation unless otherwise stated
in the material speci?cation.
12.2.2Except as indicated in Table A1.2,Series 300,XM-15,S30415,S30815,S31725,S31726,and
S32615austenitic chromium-nickel steels,when speci-
?ed on the purchase order,shall be capable of meeting
the test for resistance to intergranular corrosion speci?ed
in15.2.
12.2.3For grades stabilized with titanium or colum-bium,refer to Note4.
NOTE4—Solution-annealing temperatures above1950°F[1066°C] may impair the resistance to intergranular corrosion after subsequent exposure to sensitizing conditions in the stabilized grades,Types
309Cb,309HCb,310Cb,310HCb,316Ti,316Cb,321,321H,347,
347H,348,and348H.When intergranular corrosion is of concern,
the purchaser should specify the corrosion test of15.2(to be conducted on sensitized specimens).The manufacturer may,may if necessary,use a lower temperature resolution anneal or a stabilization anneal after a high temperature solution anneal in order to meet corrosion test requirements.Consideration should be given to the corrosive media before using a stabilization anneal at less than 1800°F[982°C],as such treatment may not be equally effective for
all media.
12.2.4For the stabilized H types,it is noted that
the heat treatment requirements shown in Table A1.2 differ as a function of whether the material was cold worked or hot?nished.
12.2.4.1As evidence that the materials are ade-quately solution annealed309H,309HCb,310H,and 310HCb shall exhibit a grain size of six or coarser as determined in accordance with Test Methods E112.
12.2.5The chromium-manganese-nickel types (201,202,S20103,S20400,S20153,S21800,XM-17, XM-18,XM-19,XM-29,and XM-31)shall be solution annealed to meet the mechanical property requirements
of the applicable material speci?cation and,to exhibit adequate resistance to intergranular corrosion(see15.2). For S20161,the heat treatment is speci?ed in Table
A1.2.
12.2.5.1Note that some of these types may contain high carbon content that can adversely affect resistance to intergranular corrosion.
12.3Duplex Types—The duplex types shall be solution annealed in accordance with Table A1.2.
859
12.4Martensitic and Ferritic Types:
12.4.1The chromium steels(S32803,400Series, S40945,S41045,S41050,S41500,S44400,S44635, S44660,S44700,S44735,S44800,XM-27,and XM-33)shall be heat treated in such a manner as to satisfy all the requirements for mechanical and bending properties speci?ed in the applicable material speci?ca-tion and(except for400series,S41050,and S41500) to provide for adequate resistance to intergranular attack.
12.4.2For S41500,heat to1750°F[955°C]mini-mum,air cool to200°F[93°C]or lower prior to any optional intermediate temper and prior to the?nal temper.The?nal temper shall be between1050°F [566°C]and1150°F[621°C].

2
in.[12.70mm]inclusive,per inch[25.40mm]of gage length per minute,or at a crosshead speed that will give a strain rate within this range.For the purposes of this speci?cation,the rate of strain may be determined by a strain-rate pacer,indicator,or controller,or by dividing the unit elongation by the elapsed time from yield strength to fracture.
13.2Hardness Test—Hardness tests may be made on the grip ends of the tension specimens before they are subjected to the tension test.
13.3Bend Test:
13.3.1Bend test specimens(when required)shall be taken from?nished material and shall be selected in the transverse direction or as indicated in the applicable material speci?cation or as agreed upon by the seller and the purchaser.In the case of transverse bend test specimens,the axis of bend shall be parallel to the direction of rolling.

15.Special Tests
15.1If other tests that are thought to be pertinent
to the intended application of the material covered by
the purchase speci?cation are required,the methods and limits shall be agreed upon between the seller and
the purchaser and speci?ed on the purchase order.
15.2Resistance to Intergranular Corrosion:
15.2.1The intergranular corrosion test,Practice E
of Practices A262,is not required unless it is speci?ed
on the purchase order.All austenitic chromium-nickel types except the H types are expected to be capable
of passing this test.However,it is not necessary to actually run the test unless it is speci?ed on the purchase order.Note that Practices A262requires the test to
be performed on sensitized specimens in the low-carbon and stabilized types and on specimens representative
of the as-shipped condition for other types.In the case of low-carbon types containing3%or more molybdenum in their speci?ed composition,the applicability of the sensitizing treatment prior to testing shall be a matter
for negotiation between the seller and the purchaser. When speci?ed,all?at rolled products of the chromium-nickel series(300series)in thickness up to and including
2in.[50.8mm]nominal size shall be capable of passing the intergranular corrosion test in the as-shipped condition.In the case of heavier plates of types other than304L,304LN,309Cb,310Cb,316Cb,316L, 316LN,316Ti,317L,321,347,348,S31725,and
S31726,the applicability of this test shall be a matter
for negotiation between the seller and the purchaser.
15.2.2The H types are not normally subject to intergranular corrosion tests.However,Practice E of Practices A262may be speci?ed for Type321H when intergranular corrosion is of concern.In this case,the purchaser shall inform the seller and agree upon the requirements and these requirements shall be so stated
on the purchase order.
15.2.3Austenitic chromium-manganese-nickel types(201,202,XM-17,XM-18,XM-19,XM-29,XM-31,S20400,and S21800)are to be heat treated for intergranular corrosion resistance.When intergranular corrosion tests are required,they shall be as agreed upon between the seller and the purchaser.
15.2.4Corrosion tests are not normally required
for the400series types.Lower-carbon corrosion-resis-tant types(S44400,S44635,S44660,S44700,S44800,
S44735,XM-27,and XM-33)are heat treated for resistance to corrosion.For S44400,S44635,S44660,
S44700,S44800,S44735,XM-27,and XM-33,inter-granular corrosion testing of Practices A763,Practice
861X,Y,or Z may be speci?ed as agreed upon between the seller and the purchaser.
15.3Detrimental Intermetallic Phases in Duplex Stainless Steels—The tests for detrimental intermetallic phases in wrought duplex stainless steels,Methods A, B,or C of Test Methods A923,are not required unless it is speci?ed on the purchase order.All duplex (austenitic-ferritic)types that are listed in Test Methods A923are expected to be capable of passing these tests.However,it is not necessary to actually run the tests unless speci?ed on the purchase order.The applicability of these tests to duplex stainless steels not listed in Test Methods A923shall be a matter for negotiation between the seller and the purchaser.

DIMENSIONS,ETC.—SI UNITS
A2.1Listed in Annex A2are tables showing the
permissible variations in dimensions expressed in SI
units of measurement.
TABLE A2.1
PERMISSIBLE VARIATIONS IN THICKNESS FOR
HOT-ROLLED SHEETS IN CUT LENGTHS,COLD-
ROLLED SHEETS IN CUT LENGTHS AND COILS
Note1—Thickness measurements are taken at least10mm from
the edge of the sheet.
Note2—Cold rolled sheets in cut lengths and coils are produced
in some type numbers and some widths and thicknesses to tolerances
less than those shown in the table.
Note3—For speci?ed thicknesses other than those shown,the tolerances for the next higher thickness shall apply.
