I don't really know. I have a sheet on 52100, which is pretty high in Chromium, as far as forging steels go, and only has 1.3 - 1.6 Chromium, and the one you list has 5%!!
I wonder if what you have is some type of stainless?

Nope - I guess it's not stainless. Stainless - to be called "stainless" - requires more chromium than that. Like maybe 10%.

I think you're pretty close on that A2 choice:

   1.0% C, 1.0% Mn, 5.0% Cr, 0.3% Ni, 1.0% Mo, 0.15–0.50% V

Lot of guys use it.

A-2 Tool Steel
    Heat treat temperature    1700-1900 F
    Quench    Air
    Hardness    Rockwell 59c-62c
    Applications    A2 can be used in the same applications as both O1 and W1, but the heat-treated air-hardening steels have deeper hardenability and there is less movement or distortion during heat treatment.
