2、ase of revision, the year of last revision. 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 sp

3、ecification covers cold-rolled commercial steel(CS) sheet in coils and cut lengths, in which the maximum ofthe specified carbon range is over 0.15 and not over 0.25 %,and the maximum of the specified manganese range is not over0.90 %. This material is ordered to chemical composition.1.2 This specifi

4、cation is not applicable to the steels coveredin Specifications A109/A109M and A1008/A1008M.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used indepen

5、dently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.2.
