This specification covers cold-rolled carbon steel strip in cut lengths or coils, furnished to closer tolerances than coldrolled carbon steel sheet, with specific temper, with specific edge or specific finish, and in sizes as follows:

Cold-rolled strip is produced with a maximum specified carbon not exceeding 0.25 percent.

Strip tolerance products may be available in widths wider than 2315⁄16 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.

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.

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.

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.

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.
