INFI, is tough steel?

Was the FBM LE done at a higher hardness by any chance? Mine is the toughest INFI I have out of my users. I beat her so hard I got sheetmetal to fuse to both sides of the blade yet no edge damage.

No, the earliest models where much harder, but the FBM's may have been close. I know I beat my CG FBM hard and it suffered no damage in any way.
 
Will there is good info in it. I know that depending on how sensitive your measuring equipment is, there are minimum levels of elements that cannot be detected. I would bet that in every instance Nitrogen is in there and it is not showing up on the test. The original INFI test showed it. What I do remember was the original modified INFI in the basic line lacked Cobalt for sure. So it could be that the later INFI used by busse is a spinoff of the Modified INFI.

As for testing the original INFI, I found the post by another member:

In another post, Mr. Busse agreed that my analysis was correct, with the addition of .11% nitrogen and .5% carbon, which the radioactive isotope spectral analysis can't detect. So, the complete formula is:

V .36%
Cr 8.25%
Fe 87.79%
Co .95%
Ni .74%
Mo 1.3%
C .5%
N .11%

These numbers should not be assumed to be exactly right, the cobalt at .95% is probably supposed to be 1.0%, but they should be close.

Which indicates that spectral analysis does not detect N or Carbon.

Why does no one make knife from A8 if INFI and CPM3V are so good?

Cuz look just how long it took us just to get a B8 outta Wauseon and now we need a B13 before we move back to the A's! :p Well, unless the A8 folds... :eek: :D

Serious guess: Heat treat issues?

It's not just about the steel. It is also the heat treat, and just maybe, the heat treat of more complex metals is complex and takes longer, which increases processing time. This adds cost, and it is not cost effective for many companies. Having said that cpm3V has become fairly common these days. But why A8 isn't, or more correctly modified A8 isn't used is beyond me. If I was a knife maker and had the ability to do proper heat treat I would certainly try modified A8. But I am not, and Jerry is using something better, so I have no need to go elsewhere.
 
This.^
And Jerry is a truly master heat treater. He has a brilliant mind too.
 
Jerry is an Idol!
Infi steel is him and stop. Other bla bla blabla. I know King Jerry is Untouchble .
INFI for EveR
