Material ASTM A333-Gr.8 has been added to the low-temperature seamless pipes listed in Table A-1 of GB20801.2; however, there is no corresponding ASTM-standard forged product for low-temperature forgings. Therefore, what material should be chosen for the flange forgings of such pipes?

Refer to the appendix of GB/T 13401-2017
