Distinguish between 15CrMoG and 20G, etc

At the construction site, some pipes have the same specifications; the anti-corrosion paint has been applied but no markings are present, or the markings are incorrect. How can one distinguish them at the site?
Handheld spectrometer or portable spectrometer. There are both domestic and imported options, with prices ranging from a few thousand to several hundred thousand yuan, depending on your needs.
I work in a design firm; I can only say that I’ve seen them. Since I’m not from the construction or procurement side, I can’t provide any recommendations
Just take a spectrum; it’s easy to distinguish

I got a preliminary consultation – the cheapest domestic options cost over 100,000, but analyzing C would require 500,000. So it’s still not cheap
