This standard specifies hot-rolled steel plates (hereinafter referred to as steel plates) that are used for pressure vessels, high-pressure equipment, and other structures, and have good weldability, a tensile strength of 780 N/mm, and a yield strength of 685 N/mm. stipulate the following. The steel materials specified in Annex 3 and Annex 4 also form part of this standard. However, the contents of Annexes 2 to 4 are complete in themselves and independent of the contents stipulated in the main body, and the stipulated items in the main body cannot be partially applied. Similarly, some of the items specified in Annexes 2 to 4 cannot be applied to the steel specified for the main body.
