INFI question ?

Oh, this should be fun...:eek: I don't think so, but I am no expert...:( I'd need more INFI for that...:D
 
Truth: INFI is not A2

Could-be-true: INFI was forged in the center of Earth billions of years ago, and Jerry has the only known method for extracting it.

That sounds kinda funky.
 
No, the composition has been revealed, it was determined at an independent lab. It was not A2.

INFI is a great steel,but it is kinda a secret,but it has to be a steel we have all heard of with a different heat treat.In all the steel listings in the world there is no infi (I dont think)so therefore it must be a normal kind of steel with different properties.

I believe this has to be Cliff's shortest post ever!!!;) :D :cool:
 
Perhaps Jerry could chime in here and give us a little insight. I've read past quotes of his concerning INFI, but it certainly is not crystal clear.

Let me quote myself from one of my old posts:


I think the answer to this riddle is that Jerry Busse designed INFI himself. Here are a couple of quotes among many I've seen which have lead me to this conclusion:

Ron Hood:

"Busse Combat Knives has just introduced a new steel called INFI. Historically, developing new steel has been extremely expensive due in part to the large quantities that had to be run. There are, however new processes in steel manufacturing which allow for small quantifies to be made. Couple this with state-of-the-art computer programs that can test an analysis before actual production begins and the costs become much more manageable.

With these new systems in place Busse Combat set out to develop a steel specifically for combat and survival knife applications that features enormous wear resistance, toughness levels never before dreamed of, ease of maintenance and easy field re-sharpening.

After signing a confidential disclosure form with Busse Combat I was allowed to examine the analysis of INFI. These guys are really keeping a tight lid on this steel until they have patent protection. It seems to defy many rules of knife making metallurgy. It also introduces a new steel manufacturing process to the cutlery industry that is sure to have long lasting ramifications.

I searched through every book that I have on modern steels and I was unable to find anything similar. I questioned a number of metallurgists about one of the key elements and they were unaware of its use in any tool steel. I was able to examine the patent applications filed by Busse Combat and the initial searches done by their attorneys look very promising."

And Jerry Busse, himself:

"Are we excited about INFI? Oh yeah! In fact it is difficult to contain ourselves. We have invested a lot of time and money in this project. We were prepared to invest more until we got it right. Luckily, more than ten years and countless bucks later we hit the jackpot!"

From what I've 'heard' infi does have other industrial uses (like A2) no, I wasn't told what they are. Jerrys heat treat takes a superior steel to new neuclear heights. Perhaps M-infi is the industrial steel and infi is a tweaked version with that special heat treat? Only the shadow knows. BRAAAHAAAHAAAA!!!!:p :p

Turns out Nitrogen is the "secret" ingredient that differentiates INFI from the others.

And, it turns out Crucible also uses Nitrogen in S30V to help facilitate it's incremental improvements over BG-42.
 
I harvested some old posts on this subject...sorry, I can't give full credit on the 1st one (I didn't save the posters name in my file), but Jerry Busse posted the 2nd note:

Originally posted by ET from Panama City FL:

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% 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

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.

Congratulations to the first 4 posters to name the rather unique ingredient, NITROGEN, in a single guess! The winners are Rob Simonich, Bagman, Bob Irons, and Ugly Jim! Great work boys! We’ll be contacting you by e-mail within the next week.

We at Busse Combat have had a great time with this and want to thank all of the forum members who participated. Sorry I wasn’t able to post immediately at 11:00 p.m. but I had lots of answers to wade through.

A little bit more about INFI.

Carbon makes up approximately .50 with Nitrogen hitting the .11 mark. The nitrogen combines with some of the other elements and enables INFI to deliver enormous levels of toughness and excellent wear resistance at high hardness. The relative ease of re-sharpening has, likewise, become one of its hallmarks.

Thanks again,
Jerry Busse
