2、ption 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 Department of Defense.1.
3、 Scope*1.1 This specification covers carbon steel plates, forging quality, intended for forging, quenching-and-tempering, and similarapplications in which uniformity of composition and freedom from injurious imperfections are important.1.2 The plates are available in six grades, or chemical composit
4、ions.1.3 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended useor service will be utilized. See Appendix X3 of Specification A6/A6M for information on weldability.1.4 The values stated in either inch-pound SI units or SIinch-pound
5、units are to be regarded separately as standard. Within thetext, the SI units are shown in brackets. The values stated in each system aremay not be exact equivalents; therefore, each systemmustshall be used independently of the other. Combining values from the two systems may result in non-conforman
