Which teacher knows: What domestic material grade is the Japanese material grade SS590 equivalent to? Thanks!

There is the "World Steel Number Comparison Manual" I posted in the forum recycle bin. You can download it for free and search it. I will give you a rough look. There are SS330, SS400, SS490, and SS330 corresponds to GB/T700. The 1988 standard Q195, Q215A(B), SS400 corresponds to Q255A(B), SS490 corresponds to Q275, SS590 seems to have not been found yet, but you can also make an analogy, they all belong to the ordinary carbon structural steel category, if SS590 exists.

Some people here say that SS590 corresponds to domestic 45# steel, right?

No, this 590 is a low-temperature steel. There is no specific comparison grade with China yet.
