Scope*1.1 This specification covers structural quality carbon steelplates furnished to chemica
3、l composition requirements.1.2 The plates are available in several standard steel gradesand non-standard grades.1.3 The plates are usually furnished in the as-rolled (hot-rolled) condition.1.4 Supplementary requirements are provided for additionalrequirements that may be specified on the order.1.5 W
4、hen the steel is to be welded, it is presupposed that awelding procedure suitable for the grade of steel and intendeduse or service will be utilized. See Appendix X3 of Specifica-tion A6/A6M for information on weldability.1.6 The values stated in either SI units or inch-pound unitsare to be regarded
5、 separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.2. Referenced Documents2.1 ASTM Standards:2A6/A6M Specification f
