This is the chemical make-up of IFNI steel as confirmed by Jerry Busse.

V .36% Vanadium
Cr 8.25% Chrome
Fe 87.79% Iron
Co .95% Cobalt
Ni .74% Nickel
Mo 1.3% Molybdenum
C .5% carbon
N .11% Nitrogen

As you can see, there is .11% Nitrogen in the steel. Radioactive isotope spectral analysis can not detect Nitrogen and this may be the reason that it did not show up in this test. The problem is that this type of testing can not detect carbon either, so maybe a different type of testing was used.

.5% carbon is enough to make a very good knife steel. Combining it with the other elements in INFI is probably what makes this such a great steel. Then of course, you have the proprietary heat treat. It is the combination of all these factors that make INFI the excellent knife steel it is.

and this one is cool.

This is an interesting tidbit:

Crucible is putting .2 Nitrogen in their powdered process of CPM-S30V.

This is the first time I have heard this claim.
