Non-Destructive Identification of Stainless Alloys
Non-Destructive Identification of Stainless Alloys
(OP)
For the most part our reactors and tanks are 316L stainless. Most of the piping we have on site is 316 with some amount of 304 mixed in. We are wanting to work back through and identify what is 304 and what is 316.
Is there any easy means for testing where the piping and fittings are not clearly marked?
I have found a table of acid test on Engineering Tool Box http://www.engineeringtoolbox.com/identification-s...
I additionally spoke to our local recycling center and they said they had a hand held alloy identifying analyzer made by Nycom?? I have not be able to find any information on such a tool.

Thank you for the quick reply!!
It looks like I had the spelling wrong for the hand held unit, it is Niton by ThermoScientific. Let me chase down the PMI!! Thank you again.

One note, these devices will tell you the difference between 304 and 316. It will not tell you the difference between 304 and 304L.

There are differences in style, software, and interface, but all of them work acceptably.
type "handheld xray analyzer" into google and start reading.
Bruker, ThermoFisher, Spectro, Olympus, Oxford and few others.
Personally I don't like ones with removable electronics, but I do like removable batteries (allows you to carry extras into the field for a full day of work).

Good you brought out the spot tests, which are simple and economical.
