Cor-Ten A equivalent to ASTM?

What is the equivalent of Cor-Ten A to ASTM?

I think there are two different specs that are called Cor-Ten. ASTM A588 is one, I believe, but don't recall the second. It may have been a plate/ sheet difference.

There should be some useful info on this previous post of mine:

Took some googling around, but it seems A588 Gr. A is the Cor-Ten B, which is a plate spec. Cor-Ten A is a sheet spec, and is A242 Type 1. I also find a reference to A606 Type 4 as Cor Ten A.
