What is Buss's infi steel most similar to?

Some people used to say it was like A8, but I think that has been debunked.
The nitrogen makes it different than most. Where is Cobalt when we need him?
 
It is most similar to a big, gruff guy walking out of a huge explosion with a few minor scratches on his grizzly face.
Also, the explosion was caused by the guy's own blinking.
 
I'm pretty sure it's close to steel.

I've heard its very close in use to cmp3v. But property wise I have no idea.
 
I think Jerry replied to a question like this once, his answer was SR101.

I have also heard people say its similar to 52100.

What it does have over both those steels is much more corrosion resistance.
 
From my experience INFI has significant poorer edge retention than 52100, anyway INFI are much better at corrosion resistance though..

poorer edge retention???!! first time i've heard that said bout INFI
 
Indestruct-onium.....its off the Periodic chart well above 103...Pu (plutonium is like 94 for example)!!!:eek::D

I'm not sure it was significantly poorer, But I believe Jerry did say the edge retension was less, on INFI, but that eliminated chipping. So INFI rolls, and SR101 can chip. I like the SR101 edge holding capability compared to INFI, and I'll take the chips over the rolls.

+1 That's what I remember.....
 
To begin this post let me say that I am huge fan of Busse knives and infi. I have thousands of dollars invested in them, and bought 2 this month alone. Having said that just like no tool perfect for every job, no knife steel can be the best match for all applications; what Infi does is find one of the very best compromises of performance characteristics for knives with a slight bias toward larger hard use applications where durability is the priority. While crucible provides charts comparing the performance qualities of its various steels, Busse prefers to keep a bit of the magic and mystery behind the curtain, which is fine, but means that we must piece together “Jerry said” quotes and temper those with our observations. As a broad generalization steels (even at a given hardness) will have a trade off between wear resistance (which generally coordinates with edge retention, although it depends somewhat on the application and cutting media) and toughness (which generally correlates with the ability to take abuse). Steels like s7 excel at toughness but have poor wear resistance; s90 has exceptional wear resistance but poor toughness. Infi is between the two, as is its competitor cpm3. Infi I believe has nearly the toughness of s7 but much better wear resistance (though wear resistance is no where near something like s90v). Comparing infi to to cpm3v, based on my experience, Infi likely is tougher, corrosion resistance is definitely superior, but guys the edge retention is simply not as high for most applications. If you have ever tried to grind or re-profile an edge on infi and cpm3v or even s30v back to back, it is much easier to remove the steel molecules on the infi blade. This can be an advantage since Infi is much easier to resharpen and takes a wicked sharp edge, but it also means infi gives up a little on the wear resistance. It is also worth noting that in Infi’s favor, there are plenty of microscope videos floating around that show that cpm3v dulls with “microchip” formation while infi tends to roll (rolling is a superior characteristic). That’s my 2 cents; I am sure others may disagree, I am happy to learn from others who have more experience working with steel.

Also INFI sharpens itself:cool::thumbup:

But SR101 seems to never need to be sharpened:eek::thumbup:

So it's a Win for Busse!!:D

Isn't SR101 just 52100 with the famous Busse heat treat?
