I'd take it to an analytical chemist who's got an X-ray spectrophotometer. He'll zap a sample with X-rays, and the nuclei will re-emit a spectrum of X-rays which identify the elements in the sample. It should cost less than US$100.

Add some acid on the sample. If you want the stainless steel(doesn't matter if is lower or higher in Cr) well a drop of vinegar for instance would do the trick. Let it dry naturally and if there's some traces of rust, that material is NOT stainless at all.

I agree with the previous answers but add a "quick and dirty" check which may be useful. The lowest grades of stainless steel, ie those with say 11-13% Cr only are magnetic. The next "level" up, with Ni added are non magnetic. Thus using a magnet may help to suggest whether say a 316 SS indeed is so, rather than an inferior 410 SS. But be careful, because the next "level" up, duplex stainless steels are weakly magnetic.

Ask for a material certificate from the supplier and save yourself a lot of time!

use quantometer, with radiation of light over sample, quatometer determine percent of material content.

do the positive material identification test
