Standard Specification for Commercial Steel (CS), Sheet, Carbon (0.16 % Maximum to 0.25 % Maximum), Cold-Rolled
ABSTRACT
This specification covers standard requirements for cold-rolled commercial steel sheet coils and cut lengths. The cast or heat analysis of the steel shall conform to the chemical requirements for carbon, manganese, phosphorus, and sulfur. Unspecified elements may be present. Limits on additional elements such as copper, nickel, chromium, molybdenum, vanadium, and columbium shall be stated. The material shall also conform to the required bending properties.
SCOPE
1.1 This specification covers cold-rolled commercial steel (CS) sheet in coils and cut lengths, in which the maximum of the specified carbon range is over 0.15 and not over 0.25 %, and the maximum of the specified manganese range is not over 0.90 %. This material is ordered to chemical composition.
1.2 This specification is not applicable to the steels covered in Specifications A109/A109M and A1008/A1008M.
1.3 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.
1.4 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
