1.Scope*
1.1This specification2covers a group of general require-ments that,unless otherwise specified in the purchase order or in an individual specification,shall apply to rolled steel plate, sheet,and strip,under each of the following specifications issued by ASTM:Specifications A167,A176,A240/A240M, A263,A2,A265,A666,A693,A793,and A5.
1.2In the case of conflict between a requirement of a product specification and a requirement of this specification, the product specification shall prevail.In the case of conflict between a requirement of the product specification or a requirement of this specification and a more stringent require-ment of the purchase order,the purchase order shall prevail. The purchase order requirements shall not take precedence if they,in any way,violate the requirements of the product specification or this specification;for example,by waiving a test requirement or by making a test requirement less stringent.
1.3The values stated in either inch-pound units or SI units are to be regarded separately as standard.Within the text,the SI units are shown in brackets,except that when A480M is specified,Annex A3shall apply for the dimensional tolerances and not the bracketed SI values in Annex A
2.The values stated in each system are not exact equivalents;therefore,each system must be used independently of the other.Combining values from the two systems may result in nonconformance with the specification.
1.4This specification and the applicable material specifica-tions are expressed in both inch-pound and SI units.However, unless the order specifies the applicable“M”specification designation[SI units],the material shall be furnished in inch-pound units.

6.2.4The purchaser is permitted to make the requirements for any element more stringent,that is,require higher mini-mums for elements having minimum requirements or ranges with minimum requirements,or requiring lower maximums for elements having specified maximums,or ranges with maxi-mums.The purchaser is not permitted to make chemical requirements less stringent.
6.2.5Analysis limits shall be established for specific elements rather than groups of elements,including but not limited to all others,rare earths,and balance,unless all elements in such a group are similar in technical effect and are associated in typical methods of chemical analysis.
6.3The steel shall not contain an unspecified element for the ordered grade to the extent that the steel conforms to the requirements of another grade for which that element is a specified element having a required minimum content.For this requirement,a grade is defined as an alloy described individu-ally and identified by its own UNS designation in a table of chemical requirements within this specification or any specifi-cation listed within the scope as being covered by the specifi-cation.
6.4The producer is not permitted to certify that material is in compliance with an ASTM product specification when the purchase order has required that the material contain as a minimum or range an element that is neither a specified element nor an intentionally added unspecified element for the ordered grade in accordance with the definitions of Test Methods,Practices,and Terminology A751.
7.Product Analysis
7.1The purchaser is permitted to perform a product analysis (formerly check analysis)to verify the identity of thefinished material representing each heat or lot.Such analysis shall be made by any of the commonly accepted methods that will positively identify the material.
7.2The chemical composition determined in accordance with7.1shall conform to the limits of the material specification within the tolerances of Table A1.1,unless otherwise specified in the applicable material specification or the purchase order. The allowable variation of a particular element in a single sample for product analysis is permitted to be either above or below the specified range.However,percentages must exhibit the same tendencies in all samples;that is,the several determinations of any individual element in a heat shall not vary both above and below the specified range.
8.Material Test Report and Certification
8.1A report of the results of all tests required by the product specification shall be supplied to the purchaser.This material test report shall reference the product specification designation and year date indicating that the material was manufactured, sampled,tested,and inspected in accordance with requirements of the product specification and has been found to meet those requirements.The material test report shall report the melting process when the purchase order requires either a specific type of melting or requires that the melting process used is to be reported.
8.1.1The report shall indicate the type of steel.If certifying that the material conforms to the requirements for more than one type of steel,the manufacturer may indicate each type of steel on the report,or may issue a separate report for each type of steel.
8.2A signature is not required on the report.However,the document shall clearly identify the organization submitting the report.Not withstanding the absence of a signature,the organization submitting the document is responsible for its content.
8.3A material test report,certificate of inspection,or similar document printed from or used in electronic form from an electronic data interchange(EDI)transmission shall be re-garded as having the same validity as a counterpart printed in the certifiers’facility.The content of the EDI transmitted document must meet the requirements of the invoked ASTM standard(s)and conform to any existing EDI agreement be-tween the purchaser and the supplier.Notwithstanding the absence of a signature,the organization submitting the EDI transmission is responsible for the content of the report.
8.4Whenfinished material is supplied to a purchase order specifying the product specification,the organization supply-ing that material shall provide the purchaser with a copy of the original manufacturer’s test report.
N OTE2—Notwithstanding the absence of a signature,the organization submitting the report is responsible for the content of the report.

8.4.1When the original manufacturer’s test report was provided by EDI to the organization supplying thefinished material to the purchaser,the organization supplying the finished material shall provide to the purchaser a printed form of the original test report or shall retransmit the test report by EDI to the purchaser.In either case,the test report shall be complete with the full identification of the original manufac-turer and with all data provided on the test report of the original manufacturer.
9.Permitted Variations in Dimensions and Weight
9.1Sheet,strip,and plate shall conform to the permitted variations in thickness,width,length andflatness,and other properties when specified,as listed in Annex A2and Annex A3 for A480and A480M respectively,for the ordered product form,or as agreed upon by seller and user and specified in the purchase order.
10.Workmanship
10.1The material shall be of uniform quality consistent with good manufacturing and inspection practices.The steel shall have no imperfections of a nature or degree,for the type and quality ordered,that will adversely affect the stamping, forming,machining,or fabrication offinished parts.
10.2Sheet,Strip,and Plate—For sheet,and strip with No. 1finish and plate with hot-roll anneal or hot-roll anneal and picklefinish it is permitted to grind to remove
surface
imperfections,provided such grinding does not reduce the thickness or width at any point beyond the permissible varia-tions in dimensions.An iron free abrasive wheel shall be used for such grinding and shall be operated at a speed ample to ensure that defective areas are cleanly cut out.
11.Finish for Sheet
11.1The types of finish available on sheet products are:11.1.1No.1Finish —Hot-rolled,annealed,and descaled.11.1.2No.2D Finish —Cold-rolled,dull finish.11.1.3No.2B Finish —Cold-rolled,bright finish.
11.1.3.1Bright Annealed Finish —A bright cold-rolled fin-ish retained by final annealing in a controlled atmosphere furnace.
11.1.4No.3Finish —Intermediate polished finish,one or both sides.

11.1.9TR Finish —Cold-worked to obtain specified proper-ties.
N OTE 4—Explanation of Sheet Finishes:
No.1—Commonly referred to as hot-rolled annealed and pickled or descaled.This is a dull,nonreflective finish.
No.2D —A smooth,nonreflective cold-rolled annealed and pickled or descaled finish.This nondirectional finish is favorable for retention of lubricants in deep drawing applications.
No.2B —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.1or 2D finishes.Product with 2B finish is normally supplied in the annealed plus lightly cold-rolled condition unless a tensile-rolled product is specified.
Bright Annealed Finish —A smooth,bright,reflective finish typically produced by cold rolling followed by annealing in a protective atmosphere so as to prevent oxidation and scaling during annealing.
No.3—A linearly textured finish that may be produced by either mechanical polishing or rolling.Average surface roughness (R a )may generally be up to 40micro-inches.A skilled operator can generally blend this finish.Surface roughness measurements differ with different instru-ments,laboratories,and operators.There may also be overlap in measure-ments of surface roughness for both No.3and No.4finishes.
No.4—A linearly textured finish that may be produced by either mechanical polishing or rolling.Average surface roughness (R a )may generally be up to 25micro-inches.A skilled operator can generally blend this finish.Surface roughness measurements differ with different instru-ments,laboratories,and operators.There may also be overlap in measure-ments of surface roughness for both No.3and No.4finishes.
No.6—This finish has a soft,satin appearance typically produced by tampico brushing a No.4finish.
No.7—Has a high degree of reflectivity.It is produced by buffing a finely ground surface,but the grit lines are not removed.It is chiefly used for architectural or ornamental purposes.
No.8—This is a highly reflective,smooth finish typically produced by polishing with successively finer grit abrasives,then buffing.Typically,very faint buff of polish lines may still be visible on the final product.Blending after part assembly may be done with buffing.
TR Finish —The finish resulting from the cold-rolling of an annealed and descaled or bright annealed product to obtain mechanical properties
higher than that of the annealed condition.Appearance will vary depend-ing upon the starting finish,amount of cold work,and the alloy.
Architectural Finishes —Sometimes described as a No.5finish,these are a separate category and may be negotiated between buyer and seller,as there are many techniques and finish variations available throughout the world.
11.1.10Architectural finish,No.5,or other proprietary names are special finishes.
11.1.11Note 4is not meant to be restrictive or to be used as a basis for rejection but is intended to give general guidelines.Various production methods may be used to obtain these finishes.
11.1.12Sheets can be produced with one or two sides polished.When polished on one side only,it is permitted to rough grind the other side in order to obtain the necessary flatness.
12.Finish for Strip
12.1The various types of finish procurable on cold-rolled strip products are:
12.1.1No.1Finish —Cold-rolled to specified thickness,annealed,and descaled.
12.1.2No.2Finish —Same as No.1Finish,followed by a final light cold-roll pass,generally on highly polished rolls.12.1.3Bright Annealed Finish —A bright cold-rolled finish retained by final annealing in a controlled atmosphere furnace.12.1.4TR Finish —Cold-worked to obtain specified proper-ties.
12.1.5Polished Finish —Stainless steel strip is also avail-able in polished finishes such as No.3and No.4,which are explained in Note 4.
N OTE 5—Explanation of Strip Finishes:
No.1—Appearance of this finish varies from dull gray matte finish to a fairly reflective surface,depending largely upon composition.This finish 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.
No.2—This finish has a smoother and more reflective surface,the appearance of which varies with composition.This is a general purpose finish,widely used for household and automotive trim,tableware,utensils,trays,etc.
Bright Annealed Finish —See Note 4.TR Finish —See Note 4.
13.Finish for Plates
13.1The types of finish available on plates are:
13.1.1Hot-Rolled or Cold-Rolled,and Annealed or Heat Treated —Scale not removed,an intermediate finish.Use of plates in this condition is generally confined to heat-resisting applications.Scale impairs corrosion resistance.
13.1.2Hot-Rolled or Cold-Rolled,and Annealed or Heat Treated,and Blast Cleaned or Pickled —Condition and finish commonly preferred for corrosion-resisting and most heat-resisting applications,essentially a No.1Finish.
13.1.3Hot-Rolled or Cold-Rolled,and Annealed or Heat Treated,and Surface Cleaned and Polished —Polish finish is generally No.4Finish.
13.1.4Hot-Rolled or Cold-Rolled,and Annealed or Heat Treated,and Descaled,and Temper Passed —Smoother finish for specialized
applications.
14.Edges for Cold-Rolled Strip
14.1The types of edges available on strip products are: 14.1.1No.1Edge—A rolled edge,either round or square as specified.
14.1.2No.3Edge—An edge produced by slitting.
14.1.3No.5Edge—An approximately square edge pro-duced by rolling orfiling after slitting.
15.Heat Treatment
15.1The heat treatments shown in this section are to be followed unless otherwise specified in the applicable material specification.Heat treatment thermal cycles shall be separate from other thermal processing cycles;for example,in-process thermal cycles are not permitted as a substitute for the separate annealing cycle.
15.2Austenitic Types:
15.2.1The material shall be solution annealed to meet the mechanical property requirements of the applicable material specification unless otherwise stated in the material specifica-tion.
15.2.2Except as indicated in Table A1.2,Series300, XM-15,N08800,S30415,S30815,S31725,S31726,and S32615austenitic chromium-nickel steels,when specified on the purchase order,shall be capable of meeting the test for resistance to intergranular corrosion specified in18.2.
15.2.3For grades stabilized with titanium or columbium, refer to Note6.
N OTE6—Solution-annealing temperatures above1950°F[1066°C]can impair the resistance to intergranular corrosion after subsequent exposure to sensitizing conditions in the stabilized grades,Types309Cb,309HCb, 310Cb,310HCb,316Ti,316Cb,321,321H,347,347H,348,348H, S35135,and S35125.When intergranular corrosion is of concern,the purchaser should specify the corrosion test of18.2(to be conducted on sensitized specimens).The manufacturer is permitted,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 than1800°F[982°C],as such treatment is not equally effective for all media.
15.2.4For the stabilized H types,it is noted that the heat treatment requirements shown in Table A1.2differ as a function of whether the material was cold worked or hot finished.
15.2.5The 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 specification and,to exhibit adequate resistance to intergranu-lar corrosion(see18.2).For S20161,the heat treatment is specified in Table A1.2.
15.2.5.1Note that some of these types contain high carbon content that can adversely affect resistance to intergranular corrosion.
15.3Duplex Types—The duplex types shall be solution annealed in accordance with Table A1.2.
15.4Martensitic and Ferritic Types:
15.4.1The chromium steels(S32803,400Series,S40945, S41045,S41050,S41500,S43932,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 specified in the applicable material specification and(except for400Series,S41050,and S41500)to provide for adequate resistance to intergranular attack.
15.4.2For S41500,heat to1750°F[955°C]minimum,air cool to200°F[93°C]or lower prior to any optional interme-diate temper and prior tofinal temper.Thefinal temper shall be between1050°F[566°C]and1150°F[621°C].
16.Number of Tests
16.1Unless otherwise specified by the applicable material specification or by agreement between the seller and the purchaser to perform a greater number of tests,the following number of tests are to be performed.
16.1.1In the case of plate,sheet,and strip produced in coil form,two or more hardness tests(one from each end of the coil);one bend test,when required;one permeability test,when required;and one or more tension tests shall be made on specimens taken from each coil.If the hardness difference between the two ends of the coil exceeds5HRB,or equivalent, or if the material is temper rolled,tensile properties must be determined on both coil ends.
16.1.2In the case of plate,sheet,or strip produced in cut lengths,one tension test;two tension tests if the material is temper rolled(one tension test for single piece lots);one bend test when required,and one or more hardness tests shall be made on each100or less pieces of the same heat and nominal thickness rolled separately or continuously and heat treated within the same operating period,either as a lot or continu-ously.
N OTE7—The term continuously,as applied to heat treatment,is meant to describe a heat-treating operation in which one cut length follows another through the furnace.Interspersement of different melts is permis-sible if they are of approximately the same nominal thickness and are heat treated in the same operating period and under the same conditions(time and temperature).
16.1.3One intergranular corrosion test,when required,shall be selected from each heat and thickness subjected to the same heat treatment practice.It is permitted to obtain such speci-mens from specimens selected for mechanical testing.
17.Test Specimens
17.1Tension Test:
17.1.1Tension test specimens shall be taken fromfinished material and shall be selected in either or both longitudinal and transverse direction.The tension test specimen shall conform to the appropriate sections of Test Methods and Definitions A370,unless otherwise specified in the applicable material specification or agreed upon by the seller and the purchaser.

17.3Bend Test:
17.3.1Bend test specimens(when required)shall be taken fromfinished material and shall be selected in the transverse direction or as indicated in the applicable material specification 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.
17.3.2Bend test specimens from sheet and strip product shall be the full thickness of the material and approximately1 in.[25.4mm]in width.It is permitted to round the edges of the test specimen to a radius equal to one half the specimen thickness.
17.3.3The width of strip for which bend tests can be made is subject to practical limitations on the length of the bend test specimen.For narrow strip,the following widths can be tested:
Strip thickness,in.[mm]
Minimum Strip Width and Mini-mum Specimen Length for Bend
Tests,in.[mm]
0.100[2.5]and under1⁄2[12.7]
