AISI 304 vs AISI 304L - identifying which is which in a production environment
AISI 304 vs AISI 304L - identifying which is which in a production environment
(OP)
Hello!
I searched about it a lot, but still have no clue - is it possible to distinguish which is which "on the run"? I mean, I have two pieces of metal and I would like to know if it's 304 or 304L, without using any specific equipment (like using a lab to check carbon content etc.).
Is it possible in a production environment to easily tell the difference between them?

OES or LIBS are the only portable methods that will detect Carbon.
And that is what would be needed.
What does it matter?
If you can't keep traceability in your process, you have much bigger problems (a broken quality systetm).

I really appreciate your help.
It was purely a hypothetical question, mostly dictated by my curiousity.
I will read more about portable carbon detecting devices.
Stay safe!

The optical emission spectrometer is the thing that is used to do the "spark test", but such testing is best avoided.

304L is an ultra-low carbon stainless steel, the carbon content is reduced to below 0.03%, which can avoid intergranular corrosion, and in theory, the effect of stress corrosion resistance is stronger than that of 304, but the effect is not obvious in practical application.
The hardness, tensile strength and yield strength of 304 and 304L are different. The view that 304L can be used instead of 304 is wrong.
