Thread Content
This one is relatively comprehensive; what’s needed can be learned*
Well explained, great, thanks for sharing!
Borrowing the OP’s words, the standards there are from the 1990s. After downloading it, I edited the content again; the updated standards are HG/T 20553-2011, SH3405-2017, and ASME B36.10M-2022
The table cannot be downloaded. Could you share it again? Thank you very much
