Stazi,
The easiest (relatively speaking ) way to tell is to cut him a small piece off one of the lips on the pipes, say just a few mm square, away from one of the welds. Probably at the end of one of the header down-pipes. Then if you have the facilities you can use an SEM or FESEM to determine the composition by percent through x-ray detection. Even cheap SEMs have a way to read the x-rays. Your technician should be able to get a few SEM shots of the grains and grain boundaries too so that you can get a good idea of the metal by comparison.
Oh, there is EDS and EELS too but those are much more time consuming (read: costly).
