can anyone identify this steel chemistry 1

[tm0284]

i was wondering if anyone could help me identify the grade of this steel. spectrometer chemistry is shown below. could this be a2 tool steel?

C - .94
Mn - .62
Si - .23
Cr – 4.97
Mo - .97
V - 0.17
Cu - 0.13
Ni - 0.13
Al - 0.03

trace niobium (0.002)

Chemistry is correct for A2, yes.

Thanks. Do you know if there are there any other common alloys that it might fit as well?

ASTM A681 Standard Specification for Tool Steels Alloy lists the wet chemistry 'absolute range' for most tool steels.

For A2 steel... Carbon is 0.01 below lowest limit... and presence of aluminum is a curious question [in my mind]... other constituents are in-range.
