1、Designation: A 573/A 573M 05Standard Specification forStructural Carbon Steel Plates of Improved Toughness1This standard is issued under the fixed designation A 573/A 573M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year o
2、f last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers structural quality carbon-manganese-silicon steel plates in three tensile strength range
3、sintended primarily for service at atmospheric temperatureswhere improved notch toughness is important.1.2 Plates covered by this specification are limited to amaximum thickness of 1.5 in. 40 mm.1.3 If the steel is to be welded, it is presupposed that awelding procedure suitable for the grade of ste
4、el and intendeduse or service will be utilized. See Appendix X 3 of Specifi-cation A 6/A 6M for information on weldability.1.4 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard. Within the text, theSI units are shown in brackets. The values stated in e
