Unknown Material Determination
(OP)
I am trying to determine what ASTM, UNS, or DIN, etc. number a certain metallurgical sample has, based on the following composition:
Al: .036
B: <.0005
C: .21
Cr: 1.3
Cu: .15
Mn: .48
Mo: .66
Nb: <.005
Ni: 1.71
P: .066
S: .013
Si: .26
Ti: <.005
V: .26
I have tried searching on several material sites with no success. Any guidance or tips would be greatly appreciated, thanks.

Grades such as 1.7709 and 1.7710 (and many more) are well outside of alloy compositions that you will find in the US.

So the Aluminum, sulfur and silicon are contaminates from recycling some original iron product, or some mix of consumer products?

Si, even at these levels isn't just left over but very deliberate. It has an impact on phase balance and solidification.
It is an odd steel, so many of the additions look to be fighting against each other.

by using a calibrated XRD analysis device you will very quickly reveal right type of material this is assuming that it is properly grinded down to clean surface where you will perform the measurement (the top surface must be 100% free of foreign matters)
