Is Your Steel Actually Steel? The Lowdown On XRF Testing
What to use?
Use an XRF (X-ray fluorescence) machine - which is a non-destructive analytical technique used to determine the elemental composition of materials.
XRF analyzers determine the chemistry of a sample by measuring the fluorescent X-ray emitted from a sample when it is excited by a primary X-ray source.
How it works
The x-ray beam interacts with the atoms in the sample by displacing electrons from the shells of the atom. This displacement occurs as a result of the difference in energy between the primary x-ray beam emitted from the analyzer and the binding energy that holds electrons in their proper orbits.
The spacing between the orbital shells of an atom is unique to the atoms of each element, so an atom of potassium (K) has different spacing between its electron shells than an atom of gold (Au), or silver (Ag).
When electrons are knocked out of their orbit, they leave behind vacancies, making the atom unstable. The atom must immediately correct the instability by filling the vacancies that the displaced electrons left behind.
The energy lost can be used to identify the element from which it emanates, because the amount of energy lost in the fluorescence process is unique to each element.
How long does it take?
A measurement using this process and a modern handheld XRF gun can be made in a matter of seconds.
The actual time required for a measurement will depend on the nature of the sample and the levels of interest.
High percentage levels will take a few seconds while part-per-million levels will take a few minutes.
We use XRF for everything we get!
So you can be sure that your 316 is just that - 316.
