Steel,Strip,Carbon(0.25Maximum Percent),Cold-Rolled1 This standard is issued under thefixed designation A109/A109M;the number immediately following the designation indicates the year of original adoption or,in the ca of revision,the year of last revision.A number in parenthes indicates the year of last reapproval.
A superscript epsilon(e)indicates an editorial change since the last revision or reapproval.
This standard has been approved for u by agencies of the Department of Defen.
1.Scope*
1.1This specification covers cold-rolled carbon steel strip in cut lengths or coils,furnished to clor tolerances than cold-rolled carbon steel sheet,with specific temper,with specific edge or specificfinish,and in sizes as follows:
Width,in.Thickness,in.
Over1⁄2to2315⁄160.300and under
Over12.5to600mm7.6mm and under
1.2Cold-rolled strip is produced with a maximum specified carbon not exceeding0.25percent.
1.3Strip tolerance products may be available in widths wider than2315⁄16in.[600mm]by agreement between pur-char and supplier.However,such products are technically classified as cold rolled sheet.This specification does not include cold-rolled carbon spring steel,Specification A682/ A682M.The tolerances,finishes,tempers,edges,and avail-able widths and thickness differentiate cold rolled strip from the product known as cold rolled sheet which is defined by Specification A568/A568M and Specification A682/A682M.
1.4For the purpo of determining conformance with this specification,values shall be rounded to the nearest unit in the right hand place offigures ud in expressing the limiting values in accordance with the rounding method of Practice E29.
1.5The SI portions of the tables contained herein list permissible variations in dimensions and mass(e Note1)in SI(metric)units.The values listed are not exact conversions of the values listed in the inch-pound tables,but instead are rounded or rationalized values.Conformance to SI tolerances is mandatory when the“M”specification is ud.
N OTE1—The term weight is ud when inch-pound units are the standard.However,under SI the preferred term is mass.
1.6The values stated in either inch-pound units or SI units are to be regarded as standard.Within the text,the SI units are shown in brackets.The values stated in each system are not exact equivalents;therefore,each system must be ud inde-pendently of the other.Combining values from the two systems will result in nonconformance with the specification.
1.7This specification is expresd in both inch-pound units and SI units.However,unless the order specifies the applicable “M”specification designation(SI units),the material shall be furnished to inch-
pound units.

3.1.1annealing—the process of heating to and holding at a suitable temperature and then cooling at a suitable rate,for such purpos as reducing hardness,facilitating cold working, producing a desired microstructure,or obtaining desired me-chanical,physical,or other properties.
3.1.1.1box annealing—involves annealing in a aled con-tainer under conditions that minimize oxidation.The strip is usually heated slowly to a temperature below the transforma-tion range,but sometimes above or within it,and is then cooled slowly.
3.1.1.2continuous annealing—involves heating the strip in continuous strands through a furnace having a controlled atmosphere followed by a controlled cooling.
3.1.2carbon steel—the designation for steel when no mini-mum content is specified or required for aluminum,chromium, cobalt,columbium,molybdenum,nickel,titanium,tungsten, vanadium,zirconium or any other element added to obtain a desired alloying effect;when the specified minimum for copper does not exceed0.40%or when the maximum content specified for any of the following elements does not exceed the percentage noted:mangane1.65,silicon0.60,or copper 0.60.
3.1.2.1Discussion—In all carbon steels small quantities of certain residual elements unavoidably retained from raw ma-terials are sometimes found which are not specified or required, such as copper,nickel,molybdenum,chromium,etc.The elements are considered as incidental and are not normally reported.
3.1.3cold reduction—the process of reducing the thickness of the strip at room temperature.The amount of reduction is greater than that ud in skin-rolling(e3.1.7).
3.1.4dead soft—the temper of strip produced without definite control of stretcher straining orfluting.It is intended for deep drawing applications where such surface disturbances are not objectionable.
3.1.5finish—the degree of smoothness or luster of the strip. The production of specificfinishes requires special preparation and control of the roll surfaces employed.
3.1.6normalizing—heating to a suitable temperature above the transformation range and then cooling in air to a tempera-ture substantially below the transformation range.In bright normalizing the furnace atmosphere is controlled to prevent oxidizing of the strip surface.
3.1.7skin-rolled—a term denoting a relatively light cold rolling operation following annealing.It rves to reduce the tendency of the steel toflute or stretcher strain during fabrica-tion.It is also ud to impart surfacefinish,or affect hardness or other mechanical properties,or to improveflatness.
3.1.8temper—a designation by number to indicate the hardness as a minimum,as a maximum,or as a range.The tempers are obtained by the lection and control of chemical composition,by amounts of cold reduction,by thermal treat-ment,and by skin-rolling.

N OTE2—A typical ordering description is as follows:20000lb Cold-Rolled Strip,Oiled,Temper4,Edge3,Finish3,0.035by9in.by coil,5000lb max,16-in.ID ASTM A109-XX,for Toaster Shells.
5.Materials and Manufacture
5.1The steel shall be made by the open-hearth,basic-oxygen,or electric-furnace process.
5.2Cold-rolled carbon steel strip is normally manufactured from continuously cast steel with aluminum ud as the deoxidizer.However,some applications are specified as silicon killed.Ingot cast rimmed,capped and mi-killed steels are subject to limited availability.
5.3Cold-rolled carbon steel strip is manufactured from hot-rolled descaled coils by cold reducing to the desired thickness on a single stand mill or on a tandem mill consisting of veral single stands in
ries.Sometimes an anneal is ud at some intermediate thickness to facilitate further cold reduc-tion or to obtain desired temper and mechanical properties in thefinished strip.An anneal and skin pass is typically ud as thefinal step for Temper4and5.
6.Chemical Composition
6.1Heat Analysis—An analysis for each heat of steel shall be made by the manufacturer to determine the percentage of elements shown in Table1.This analysis shall conform to the requirements shown in Table1.When requested,heat analysis shall be reported to purchar or his reprentative.
6.2Product,Check,or Verification Analysis may be made by the purchar on thefinished material.
6.2.1Capped or rimmed steels are not technologically suited to product analysis due to the nonuniform character of their chemical composition and therefore,the tolerances in Table2do not apply.Product analysis is appropriate on the types of steel only when misapplication is apparent or for copper when copper steel is specified.
6.2.2For steels other than rimmed or capped,when product analysis is made by the purchar,the ch
emical analysis shall not vary from the limits specified by more than the amounts in Table2.The veral determinations of any element shall not vary both above and below the specified range.
6.3For referee purpos,if required,Test Methods,Prac-tices,and Terminology A751shall be ud.
6.4For applications where cold-rolled strip is to be welded, care must be exercid in lection of chemical composition,as well as mechanical properties,for compatibility with the welding process and its effect on altering the properties.
7.Temper and Bend Test Requirement
7.1Cold-rolled carbon strip specified to temper numbers shall conform to the Rockwell hardness requirements shown in Table 3.
7.1.1When a temper number is not specified,rockwell hardness requirements are established by agreement.
7.2It is recommended that hardness values be specified in the same scale as that which will be ud in testing the strip.7.3Bend tests shall be conducted at room temperature and test specimens shall be capable of being bent to the require-ments shown in Table 4.
7.4All mechanical tests are to be conducted in accordance with Test Methods and Definitions A 370.
8.Edge
8.1The desired edge number shall be specified as follows:8.1.1Number 1Edge is a prepared edge of a specified contour (round or square),which is produced when a very
accurate width is required or when an edge condition suitable for electroplating is required,or both.
8.1.2Number 2Edge is a natural mill edge carried through the cold rolling from the hot-rolled strip without additional processing of the edge.
8.1.3Number 3Edge is an approximately square edge,produced by slitting,on which the burr is not eliminated.Normal coiling or piling does not necessarily provide a definite positioning of the slitting burr.
8.1.4Number 4Edge is a rounded edge produced by edge rolling either the natural edge of hot-rolled strip or slit-edge strip.This edge is produced when the width tolerance and edge condition are not as exacting as for No.1edge.
