1、Designation: A573/A573M 05 (Reapproved 2009)Standard Specification forStructural Carbon Steel Plates of Improved Toughness1This standard is issued under the fixed designation A573/A573M; the number immediately following the designation indicates the yearof original adoption or, in the case of revisi

2、on, 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.1. Scope1.1 This specification covers structural quality carbon-manganese-silicon steel plates in three tensile st

3、rength rangesintended 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

4、grade of steel and intendeduse or service will be utilized. See Appendix X3 of Specifica-tion A6/A6M 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 st

5、ated in eachsystem are not exact equivalents; therefore, each system is tobe used independently of the other without combining values inany way.2.
