1.1This specification covers structural quality carbon steel plates furnished to chemical composition requirements.

1.2The plates are available in several standard steel grades and non-standard grades.

1.3The plates are usually furnished in the as-rolled (hot-rolled) condition.

1.4Supplementary requirements are provided for additional requirements that may be specified on the order.

1.5When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. See Appendix X3 of Specification A6/A6M for information on weldability.

1.6The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
