This specification covers structural quality alloy steel plates. The plates are usually specified to chemical composition requirements, but tensile properties may also be specified. When tensile properties are required, the specific requirements must be compatible with the chemical composition, condition, and plate thickness.When 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.
