Norma Astm A36

Designation: A 36/A 36M – 00a

Standard Specification for

Carbon Structural Steel1
This standard is issued under the fixed designation A 36/A 36M; 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 (e) indicates aneditorial 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 specification2 covers carbon steel shapes, plates, and bars of structural quality for use in riveted, bolted, or welded construction of bridges and buildings, and for general structural purposes. 1.2 Supplementary requirements are provided foruse where additional testing or additional restrictions are required by the purchaser. Such requirements apply only when specified in the purchase order. 1.3 When the steel is to be welded, a welding procedure suitable for the grade of steel and intended use or service is to be utilized. See Appendix X3 of Specification A 6/A 6M for information on weldability. 1.4 For Group 4 and 5 wide flangeshapes for use in tension, it is recommended that the purchaser consider specifying supplementary requirements, such as fine austenitic grain size and Charpy V-notch impact testing. 1.5 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents;therefore, each system is to be used independently of the other, without combining values in any way. 1.6 The text of this specification contains notes or footnotes, or both, that provide explanatory material. Such notes and footnotes, excluding those in tables and figures, do not contain any mandatory requirements. 1.7 For plates cut from coiled product, the additional requirements, including additionaltesting requirements and the reporting of additional test results, of A 6/A 6M apply. 2.
