INFI corrosion resistance?

When looking at the composition of INFI
C:0,50
Cr:8,25!
Co:0,95
Mo:1,30
N:0,11 (like H-1)
Ni:0,74
V:0,36

It seems nitrogen is used to make it more corrosion resistant.
But it seems INFI is able to rust. So why did Busse use nitrogen in their INFI if not for corrosion resistance?

helps keep the weight of the larger blades like the FBM and MOAB lower ;)
 
hmm, could be but unlikely.
INFI seems to rust see this post. http://www.bladeforums.com/forums/showthread.php?t=749518&highlight=infi+rust
When nitrogen is added to austenitic steels it can simultaneously improve fatigue life, strength, work hardening rate, wear and localized corrosion resistance.

I did see CPM S35VN as a promising steel and performance could be comparable to INFI ( less the magic heat treat).
I know Spyderco did a test run on a mule series. Did anyone have the opportunity to compare CPN S35VN to INFI?
This thread is NOT to diss INFI or Busse blades
I am fascinated by the INFI performance, based on both the reports of the HOG's and by "indepedent" sources that all say INFI is a fantastic steel.
I am just been haunted by the fact why this steel is not used more by other users. I know it's proprietary made steel, AND great heat treat, but i want to know why nobody else uses a comparable steel.
When looking at CPMS35VN steel this steel could be a good replacement candidate.

I believe its top secret, Really all i know is it holds up well, its resharpens easily mine have'nt rusted yet. And the best warranty i've seen or heard of. :thumbup:

my post was a little tongue-in-cheek, I truely have no clue about the makeup of INFI, but my SAR3 is awesome
 
That link with the rust is in a CF blade(compitition finish) that isn't finished out and still has some infi dimples. Leaving them this way makes then much more prone to rust, but they are less expensive.
He made some of these(and some last year that wasn't even bead blasted) in this version so it could have a low price point.
I'm not a fan of the CF finish for this reason, but he's only made a few with it.

Reg. finished INFI is about the same as stainless ATS34, or D2 in regards to rust.
As you know D2 nor INFI is a stainless, but both are about as close as you can get without being a stainless.

I find that hard to believe. :thumbdn: Many of us have NOT forgotten the negative comments you posted back in mid May concerning Busse, INFI and those of us who like the knives.
Just get to the punchline here already and save everyone some time...

Or feel free to give Jerry Busse a call. I'm sure that he can provide you with some answers if you are actually interested in the facts. Oh, and be sure to tell him how you think that...

I'm sure that attitude of yours will go far with him... :rolleyes:

Trolling, trolling ...

Calm down, post with respect.
Read more and learn, without the attitude.
If you ask the wrong question, you'll get the wrong answer.
If you're looking for a fight ... I won't allow it in the General Knife Discussion.
Wow! Why DON'T those other manufacturers use INFI?
Proprietary -- what does that word mean?
 
Well, I am NOT what you would define as an INFI fanboy, and have been critical of various things the company has done, but I can also say that you can't argue the results of the steel.

INFI has all the toughness of a high carbon steel but few of the drawbacks. Its corrosion resistance is downright amazing, given how tough the steel is. Yes, it can rust, and will definitely stain, but it doesn't rust NEARLY as badly as any other hard use steel I've ever seen.


You asked whether the nitrogen is for corrosion resistance - the answer is "yes". But INFI is not optimized for nothing but corrosion resistance - it balances many things, such as toughness and edge retention.



And I've gotta agree with Jaxx - your posts definitely come across as trollish. I've been accused of trolling when I was upset with something that happened with the Busse clan, and I still wasn't nitpicking a single example of a competition finish blade rusting to try to trash the steel as rust prone. The whole mental disorder tirade was nothing but an idiotic ad hominem attack, and does more to discredit your motives than anything else you've said. Methinks thou doth protest too much.

That's not the case IMHO . I am just suprised and angry someone has the time to keep a database of everyone who said anything bad about busse buyers in the past.
It has nothing to do with Busse as a company.
I am a spyderco collector but i don't buy every spyderco available or attack people because they like benchmade or whatever. I don't keep track who says anything bad about spyderco.
Jaxx was picking a fight with me, because i asked an honest question , and i got an honest reply. The quotes he gives were made in Whine & cheese where i can tell the dumbest things i want because nobody takes them seriously.

no one has to keep a data base. bfc does that for everyone. just pull up your profile and view started threads and it is easy to see you have some sort of agenda.

A database? Please...the last post I quoted was due to having a memory. But, OK... let's give you the benefit of the doubt about you telling the dumbest things you want, that we aren't to take seriously because that thread was in W&C....

What about this post made in the General Knife Discussion forum on 2/09/2010... This very sub-forum?

INFI has: 0.5% carbon, 8.5% Chromium, 0.74% nickel, 0.36% vanadium 1.3% molybdenum 0.95% cobalt and 0.11% nitrogen.

see http://www.ebladestore.com/steel_chart.shtml for other steel.
INFI steel is custom made for Busse. Combined with good heat treatment gives it good performance.

Is it a wonder steel? My guess is that if it was THE most fantastic steel in the world it would be offered for other applications by steel manufacturers.

They don't, so i am convinced that the metallurgist engineers in this world, either don't know their job, or are not convinced that other steels don't have similar performance or they would all start using INFI.

The people who buy Busse are convinced that INFI is the best steel available for knives. That is possible.
But does it warrant the high price? Each it's own.
I am convinced that i could sell 420J steel for 10 times the value to Brittney Spears fans because Brittney spears quenched it with her own urine!

But IMHO some Busse customers have a strong "confirmation bias"
http://en.wikipedia.org/wiki/Confirmation_bias
This bias is supported and enlarged by the other peers who confirm each others bias by gathering in peer groups like the busse forum.
The fact that the resale value is always mentioned could be an indicator that the people who buy Busses have a subcontious feeling that their knives are too expensive BUT that they can always sell it again for a high price.
It seems that the pool of customers of Busse products is rather small and that they support the myth of the INFI wonder steel to convince themselve that they didn't fell for a marketing gimmick.

Seems that you have made a point of bashing Busse under the facade of a serious question before, so this time we are to believe that you are sincere??? :rolleyes:
 
Jim in case ya interested Scott Gossman has just started using CPM S35VN !
