Materials
A so-called "Basic 8" analyzes for C, Mn, Si, P, S, Cr, Ni, Mo. (This typically costs an bout $100)
Some alloys should be checked for Cu, Ti or Cb, the last 2 for stabilized grades like 321 and 347.

lker Scientific has a chemical spot test for stainless steel, here is the link
In the [red]Carpenter Stainless Steels Working Data[/red] book, they publish identification tests

The question was how to differentiate between different grades of stainless using chemical analysis. Thanks for the inputs. I also found 3 ASTM test methods that detail chemical tests to quantify alloying constituents to determine which steel you have.
see ASTM E350 for wet chemical analysis and E281 and E 282 for spectrochemical methods.
Be cautious when using commercial labs for analysis because they seldom have adequate standards for all the elements found in stainless and can be pretty far off.
If the stainless is a mill product of known source, ask the supplier to do a gratis analysis for you.
