About a year ago we sat down with a few of the metallurgists at Buderus Mills in Germany to discuss a Nitrogen formula for our AEB-L. What we came up with is a steel that shows marked improvements in both toughness, stain resistance and. harden-ability. We also added just a touch of Vanadium to help deter grain growth.


We will be calling our new formula "NITRO-V. It will be available in 3/32, 1/8, 5/32 and 3/16 and will be a very competitive, cost effective nitrogen stainless. The 1/8" and 5/32" just got here this morning and we hope to have it up on the website within a few days. If you are considering any volume please give us a call at the office to discuss your needs.

We are really excited about this steel and others that will soon be added to our menu of fine knife and cutlery steels. Give it a shot! You won't be disappointed!

Thank you,

That sounds like great stuff.

Whatever happened with the O-2? And do you have more W-2 in the pipeline?
 
So this stuff will never have been coiled like the AEB-L we are used to, and will have less associated warp issues?
 
Salem, steels get rolled!! they also get straightened. it's the straightening and how it's done that makes the difference. When we first started processing our own bar the stuff was straightened on a stretcher. It didn't do so well. We have since added a skin pass. It is a cold roll process that seems to have helped a lot with that issue. We typically plate quench when we heat treat in my shop and don't have many problems. Most of our knives go out to Peter's. There stuff ready to grind .

Devin! Good to hear from you. We added .05 Vanadium and 1200PPM Nitrogen to the standing formula of .65c and 13.5Ch

We are still working out the details for 1.2519 which, if you look is very close to Blue#2 with added Chrome, but that's for another day.

The Nitrogen steel sounds great. Do you have any idea of a price point compared to say, AEB-L? are we looking at twice the price? 3 times the price?

We are still waiting on that Blue Baron/ Aldo Blueno steel!
 
So do you lose any of the fine/stable edge properties of AEB-L with this new mix? i have no personal experience in this regard, but I had read/heard that this was slight issue with 19C28N. As for the Blue stuff, the Germans make several steels that type from what I see. I referred to 1.2442/115W8 as "Blue #1.5" because it had a carbon content about like Blue #2 but a tungsten content closer to Blue #1. I made a sujihiki out of that stuff and it got so sharp that if you thought about it for more than 5 seconds, you would bleed.;)
 
Very cool, I already love AEB-L so if this is an upgrade then all the better. Plus it's got a cool name :thumbup:
 
Here are JMatPro simulations of the carbide content and composition of the matrix at two different austenitizing temperatures (these simulations assume infinitely long hold time). No VC carbides were predicted, which is why they are not included in the table.

So these simulations indicate that Nitro-V would have similar corrosion resistance (matrix Cr%) and wear resistance (M7C3%) to 12C27 but with greater peak hardness (matrix C%). Or it would have superior toughness and corrosion resistance to 13C26/AEB-L but poorer wear resistance.

Thats for the info, Larrin. Either way, would the main benefit in a kitchen knife application be increased corrosion resistance at the expense of some abrasion resistance? Would their be any difference in the ability to take super fine, stable edge?

Sweet! I'm ready to test a free sample. ;)

But more seriously, have you tested out tempering temps vs. hardness & some sort of toughness measure yet?
 
Don't know that I'll ever use it, but I just want to comment how great it is to have a steel supplier working directly with the mills to provide an alloy to specifically meet knifemakers' needs. :cool: :thumbup:

Hope you're doing well, Aldo. Allie and I missed seeing you at the Blade Show.
 
Aldo, I loved dealing with you. Is it a glitch that your web site restricts sales to Canada, or is that on purpose?
 
I can confirm that I've had ZERO issues with warp, using Aldo's AEB-L. I'm talking about .070 thick, moderately long fillet knives. No issues with the thicker stuff I've used either.
Now, it was all heat treated at Peters', so I'm not sure what, if any work they had to do, but I'm assuming none, if very little. No issues before or after HT either.
 
Aldo

have you had any samples HT by Peters thus far, or is it too new for that?
