SS Alloy identification

[Spocky]

I'm trying to ID the weld overlay material used on the interior of a pressure vessel.
Mo .24
Ni 6.72
Fe 64.52
Mn 3.38
Cr 23.75
Can anyone assist?
Thanks,
Cam

I presume that this is over plain steel.
How thick? How many passes?
How did you do the analysis? Did you have good sample preperation?

CS shell .375"
Single pass
Niton Xlp 800

I am thinking of things like ER312 (S31380), 19-9 (S30880), ER209 (S20980),
The Cr seems high for the Ni and Mn.

That is reasonably close to the analysis of 2304, duplex stainless alloy.
