A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers structural quality carbon steel plates furnis
3、hed to chemical composition requirements.1.2 The plates are available in several standard steel grades and non-standard grades.1.3 The plates are usually furnished in the as-rolled (hot-rolled) condition.1.4 Supplementary requirements are provided for additional requirements that may be specified on
4、 the order.1.5 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.1.6 The values stated in either SI units or inch-pound units a
