A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope*1.1 This specification co
3、vers cold-rolled carbon steel strip in cut lengths or coils, furnished to closer tolerances than cold-rolledcarbon steel sheet, with specific temper, with specific edge or specific finish, and in sizes as follows:Width, in. Thickness, in.Over 12 to 231516 0.300 and underOver 12.5 to 600 mm 7.6 mm an
4、d under1.2 Cold-rolled strip is produced with a maximum specified carbon not exceeding 0.25 percent.1.3 Strip tolerance products may be available in widths wider than 231516 in. 600 mm by agreement between purchaser andsupplier. However, such products are technically classified as cold rolled sheet.
5、 The tolerances, finishes, tempers, edges, andavailable widths and thicknesses differentiate cold rolled strip from the product known as cold rolled sheet which is defined bySpecification A568/A568M and from cold rolled high carbon strip which is defined by Specification A682/A682M.1.4 For the purpo
6、se of determining conformance with this specification, values shall be rounded to the nearest unit in the righthand place of figures used in expressing the limiting values in accordance with the rounding method of Practice E29.1.5 The SI portions of the tables contained herein list permissible varia
7、tions in dimensions and mass (see Note 1) in SI (metric)units. The values listed are not exact conversions of the values listed in the inch-pound tables, but instead are rounded orrationalized values. Conformance to SI tolerances is mandatory when the “M” specification is used.NOTE 1The term weight
8、is used when inch-pound units are the standard. However, under SI the preferred term is mass.1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used inde
9、pendently of the other. Combining values from thetwo systems may result in non-conformance with the standard.1.7 This specification is expressed in both inch-pound units and SI units. However, unless the order specifies the applicable “M”specification designation (SI units), the material shall be fu
10、rnished to inch-pound units.2.

Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 annealingthe process of heating to and holding at a suitable temperature and then cooling at a suitable rate, for suchpurposes as reducing hardness,
19、 facilitating cold working, producing a desired microstructure, or obtaining desired mechanical,physical, or other properties.3.1.1.1 box annealinginvolves annealing in a sealed container under conditions that minimize oxidation. The strip is usuallyheated slowly to a temperature below the transform
20、ation range, but sometimes above or within it, and is then cooled slowly.3.1.1.2 continuous annealinginvolves heating the strip in continuous strands through a furnace having a controlledatmosphere followed by a controlled cooling.3.1.2 carbon steelthe designation for steel when no minimum content i
21、s specified or required for aluminum, chromium,cobalt, columbium, molybdenum, nickel, titanium, tungsten, vanadium, zirconium or any other element added to obtain a desiredalloying effect; when the specified minimum for copper does not exceed 0.40 % or when the maximum content specified for anyof th
22、e following elements does not exceed the percentage noted: manganese 1.65, silicon 0.60, or copper 0.60.3.1.2.1 DiscussionIn all carbon steels small quantities of certain residual elements unavoidably retained from raw materials are sometimes foundwhich are not specified or required, such as copper,
23、 nickel, molybdenum, chromium, etc. These elements are considered asincidental and are not normally reported.3.1.3 cold reductionthe process of reducing the thickness of the strip at room temperature. The amount of reduction is greaterthan that used in skin-rolling (see 3.1.7).3.1.4 dead softthe tem
24、per of strip produced without definite control of stretcher straining or fluting. It is intended for deepdrawing applications where such surface disturbances are not objectionable.3.1.5 finishthe degree of smoothness or luster of the strip. The production of specific finishes requires special prepar
25、ation andcontrol of the roll surfaces employed.3.1.6 normalizingheating to a suitable temperature above the transformation range and then cooling in air to a temperaturesubstantially below the transformation range. In bright normalizing the furnace atmosphere is controlled to prevent oxidizing ofthe
26、 strip surface.3.1.7 skin-rolleda term denoting a relatively light cold rolling operation following annealing. It serves to reduce the tendencyof the steel to flute or stretcher strain during fabrication. It is also used to impart surface finish, or affect hardness or othermechanical properties, or
27、to improve flatness.3.1.8 temper a designation by number to indicate the hardness as a minimum, as a maximum, or as a range. The tempers areobtained by the selection and control of chemical composition, by amounts of cold reduction, by thermal treatment, and byskin-rolling.3.2 Refer to Terminology A

ID ASTM A 109-XX, for Toaster Shells.5. Materials and Manufacture5.1 The steel shall be made by the o
32、pen-hearth, basic-oxygen, or electric-furnace process.5.2 Cold-rolled carbon steel strip is normally manufactured from continuously cast steel with aluminum used as the deoxidizer.However, some applications are specified as silicon killed. Ingot cast rimmed, capped and semi-killed steels are subject
33、 to limitedavailability.5.3 Cold-rolled carbon steel strip is manufactured from hot-rolled descaled coils by cold reducing to the desired thickness ona single stand mill or on a tandem mill consisting of several single stands in series. Sometimes an anneal is used at someintermediate thickness to fa
34、cilitate further cold reduction or to obtain desired temper and mechanical properties in the finished strip.An anneal and skin pass is typically used as the final step for Temper 4 and 5.6. Chemical Composition6.1 Heat Analysis An analysis for each heat of steel shall be made by the manufacturer to
35、determine the percentage ofelements shown in Table 1. This analysis shall conform to the requirements shown in Table 1. When requested, heat analysis shallbe reported to purchaser or his representative.6.2 Product, Check, or Verification Analysis may be made by the purchaser on the finished material
36、.6.2.1 Capped or rimmed steels are not technologically suited to product analysis due to the nonuniform character of theirchemical composition and therefore, the tolerances in Table 2 do not apply. Product analysis is appropriate on these types of steelonly when misapplication is apparent or for cop

The several determinations of any element shall not vary bothabove and below the specified range.6.3 For referee purposes, if required, Test Methods, Practices, and Terminology A751 shall be used.6.4 For applications where cold-rolled strip is to be welded, care must be exer

Temper and Bend Test Requirement7.1 Cold-rolled carbon strip specified to temper numbers shall conform to the Rockwell hardness require
44、ments shown in Table3.7.1.1 When a temper number is not specified, rockwellRockwell hardness requirements are established by agreement.7.2 It is recommended that hardness values be specified in the same scale as that which will be used in testing the strip.7.3 Bend tests shall be conducted at room t
