Ferrous and non ferrous materials

What is the difference between SA-213 800 and SB-407 800?!! UNS 08800

They seem to be the same material

Although the ASME secII is designated to the ferrous material we can find incoloy in it so is it normal or is it a different material

In ASME Section II 2019, both the same UNS designation UNS N08800.
But in ASME Section IX, ASME SA-213 UNS N08800 is unassigned material.
I do not have any advice here.
