[MW:6599] Re: 6484] how can we differenciate between cs and kcs?

I tried to reply to this a few days ago, but I don't believe it went
through.

Handheld XRF instruments like the Thermo Scientific Niton XRF analyzer
can be used to differentiate between killed and regular carbon steel.
You would need an instrument with a silicon drift detector (SDD) that
can directly quantify light elements down to Mg on the periodic table,
which includes Al and Si. So if you are looking for Si or Al killed
steel, you need to determine the presence of these elements, or lack
thereof.

I know of one PMI application in the petrochemical industry where they
are differentiating between A53 (1030 cs) vs A106 (Si-killed A53).
A106 will have a minimum of 0.10% Si, which a Niton GOLDD analyzer can
see. If it doesn't see the Si, it is regular carbon steel. This is
done in a matter of a few seconds and non-destructively.
