(Specification)Standard Specification for Steel, Strip, Carbon (0.25 Maximum Percent), Cold-Rolled
Standard Specification for Steel, Strip, Carbon (0.25 Maximum Percent), Cold-Rolled
ABSTRACT
This specification covers cold-rolled carbon steel strip in cut lengths or coils, furnished to closer tolerances than cold-rolled carbon steel sheet. The steel shall be made by the open-hearth, basic-oxygen, or electric-furnace process. Cold-rolled carbon strip specified to temper numbers shall conform to the Rockwell hardness requirements. Bend tests shall be conducted in accordance with requirements specified.
SCOPE
1.1 This specification covers cold-rolled carbon steel strip in cut lengths or coils, furnished to closer tolerances than cold-rolled carbon steel sheet, with specific temper, with specific edge or specific finish, and in sizes as follows:
Width, in.
Thickness, in.
Over 1/2 to 23 15/16
0.300 and under
Over 12.5 to 600 mm
7.6 mm and under
1.2 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 23 15/16 in. [600 mm] by agreement between purchaser and supplier. However, such products are technically classified as cold rolled sheet. The tolerances, finishes, tempers, edges, and available widths and thicknesses differentiate cold rolled strip from the product known as cold rolled sheet which is defined by Specification A568/A568M and from cold rolled high carbon strip which is defined by Specification A682/A682M.
1.4 For the purpose of determining conformance with this specification, values shall be rounded to the nearest unit in the right hand 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 variations 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 or rationalized values. Conformance to SI tolerances is mandatory when the “M” specification is used.
Note 1: The term weight 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 each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two 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 furnished to inch-pound units.
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version

1.3 Strip tolerance products may be available in widths wider than 2323 ⁄16 in. [600 mm] by agreement between purchaser and
supplier. However, such products are technically classified as cold rolled sheet. The tolerances, finishes, tempers, edges, and
available widths and thicknesses differentiate cold rolled strip from the product known as cold rolled sheet which is defined by
Specification A568/A568M and from cold rolled high carbon strip which is defined by Specification A682/A682M.

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 used.
