ASTM A794/A794M-18

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
of the standard as published by ASTM is to be considered the official document.
Designation: A794/A794M − 12 (Reapproved 2017) A794/A794M − 18
Standard Specification for
Commercial Steel (CS), Sheet, Carbon (0.16 % Maximum to
0.25 % Maximum), Cold-Rolled
This standard is issued under the fixed designation A794/A794M; the number immediately following the designation indicates the year
of original adoption or, in the case 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 U.S. Department of Defense.
1. 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.

3.1.7 Dimensions (thickness, width, and whether cut lengths or coils),
NOTE 1—Not all producers are capable of meeting all the limitations of the thickness tolerance tables in Specification A568/A568M. The purchaser
should contact the producer regarding possible limitations prior to placing an order.
3.1.8 Coil size (must include inside diameter, outside diameter, and maximum mass),
3.1.9 Quantity,
3.1.10 Application (show part identification and description),
3.1.11 Cast or heat analysis report (request, if required), and
3.1.12 Special requirements (if any).
3.1.12.1 When the purchaser requires thickness tolerances for ⁄8 in. [10 mm] minimum edge distance (see Supplementary
Requirement in Specification A568/A568M), this requirement shall be specified in the purchase order or contract.
NOTE 2—A typical ordering description is as follows: ASTM A794-XX, Cold-Rolled Commercial Steel (CS), Grade 1018, Exposed, Matte Finish,
