Is INFI made from A-2 steel?

I was curious if INFI is a slightly modified version of A2 steel? I have heard other people mention it, and was curious if INFI is just a slightly modified version of A2? I know the heat treatment is also a main part of the overall performance and durability of the knife. Any takers or is this just a rumor. I know they slightly modify other steels like Modified INFI and Swamprat modified I think S7 anyway I was wondering. I also heard that they somehow get nitrogen into the steel, so I don't know who to believe. Any people out there in Busse land that can let the cat out of the bag I would appreciate it.
 
hope this helps

INFI

0.5% Carbon
8.25% Chromium
1.3% Molybdenum
0.36% Vanadium
0.74% Nickel
0.11% Nitrogen
0.95% Cobalt

nope. the cat stays RIGHT HERE!
 
WHAT?? I thought INFI was pure Gold!! I've been pulling my money out of stocks and real estate to buy INFI... DOH!!
 
Uncle Jarvis!!?? Infi is---ummm---Wood-chipper steel with no letters or numbers!! No heat treat is required.
 
busse has previously used a lot of a2, before the introduction of their infi. a2 has 1% carbon, wich automatically tells you that they are not the same.

There was a thread where someone was claiming that infi was identical to a8, but after many many posts telling him that when you have additional elements added to a steel mix, and you have different percentages of the ingredients and microconstituent's - you have a different steel, the poster changed it to "from the same steel family".

a8
0.5 - 0.6 %Carbon, C
5.13 %Chromium, Cr
90.0 %Iron, Fe
<= 0.5 %Manganese, Mn
1.40 %Molybdenum, Mo
<= 0.03 %Phosphorous, P
0.93 %Silicon, Si
<= 0.03 %Sulfur, S
1.25 %Tungsten, W

INFI

0.5% Carbon
8.25% Chromium
1.3% Molybdenum
0.36% Vanadium
0.74% Nickel
0.11% Nitrogen
0.95% Cobalt
 
I could care less what it is as long as it does what it does and still comes in AK and Ruck form.

I believe infi starts as A2 and is modified, to make INFI!!

no. maybe he started off likeing a2 and wanted something similar, but chemically they are to far off to be like 52100 with "a bit more chromium and vanadium" or s7 with "more chromium".

they are completely different steels, not a modification.

a2
1.00 % Carbon
5.00 % Chromium
91.7 % Iron
0.750 %Manganese
1.00 % Molybdenum
0.300 % Silicon
0.250 % Vanadium

INFI

0.5% Carbon
8.25% Chromium
1.3% Molybdenum
0.36% Vanadium
0.74% Nickel
0.11% Nitrogen
0.95% Cobalt
 
INFI has at least one other ingredient lacking in A2 - 20% Kool Aid. :thumbup:

Yeah, but if you half the carbon, leave out the Silicon and manganese, add some nickel, nitrogen and cobalt and bump the chromium, then they're similar.

Don't you see ? :rolleyes:

if it were for the silicon, tungsten, nickel and nitrogen differences, a8 would be kinda similar. and the 3% additional chromium... and the addition of vanadium...
