1、Designation: A36/A36M 12A36/A36M 14Standard Specification forCarbon Structural Steel1This standard is issued under the fixed designation A36/A36M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A number
2、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 specification2 covers carbon steel shapes, plates,
3、 and bars of structural quality for use in riveted, bolted, or weldedconstruction of bridges and buildings, and for general structural purposes.1.2 Supplementary requirements are provided for use where additional testing or additional restrictions are required by thepurchaser. Such requirements appl
4、y 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 beutilized. See Appendix X3 of Specification A6/A6M for information on weldability.1.4 The values stated in either inch-pound units or
5、 SI units are to be regarded separately as standard. Within the text, the SI unitsare shown in brackets. The values stated in each system are not exact equivalents; therefore, each system is to be usedindependently of the other, without combining values in any way.1.5 The text of this specification
6、contains notes or footnotes, or both, that provide explanatory material. Such notes andfootnotes, excluding those in tables and figures, do not contain any mandatory requirements.1.6 For structural products produced from coil and furnished without heat treatment or with stress relieving only, the ad
7、ditionalrequirements, including additional testing requirements and the reporting of additional test results, of A6/A6M apply.2.

18、ified with this ASTM designation but the product form is not listed in thescope of this specification, the material shall conform to one of the standards listed in Table 1 unless otherwise specified by thepurchaser.4. General Requirements for Delivery4.1 Structural products furnished under this spec
19、ification shall conform to the requirements of the current edition ofSpecification A6/A6M, for the specific structural product ordered, unless a conflict exists in which case this specification shallprevail.4.2 Coils are excluded from qualification to this specification until they are processed into
20、 a finished structural product.Structural products produced from coil means structural products that have been cut to individual lengths from a coil. Theprocessor directly controls, or is responsible for, the operations involved in the processing of a coil into a finished structuralproduct. Such ope
21、rations include decoiling, leveling or straightening, hot-forming or cold-forming (if applicable), cutting to length,testing, inspection, conditioning, heat treatment (if applicable), packaging, marking, loading for shipment, and certification.NOTE 1For structural products produced from coil and fur
22、nished without heat treatment or with stress relieving only, two test results are to be reportedfor each qualifying coil. Additional requirements regarding structural products produced from coil are described in Specification A6/A6M.5. Bearing Plates5.1 Unless otherwise specified, plates used as bea
23、ring plates for bridges shall be subjected to mechanical tests and shall conformto the tensile requirements of Section 8.5.2 Unless otherwise specified, mechanical tests shall not be required for plates over 112 in. 40 mm in thickness used asbearing plates in structures other than bridges, subject t
