NitroV...Any Updates???

Doesn't Nitro V have a composition closer to AEB-L/13C26 but with nitrogen and a pinch of vanadium added? It looks like it has a bit more carbon (.68% vs .62% and slightly less chromium (12.9% vs 14%) than 14C28N.
 
I plan on using Nitro V for a "mini kukri with a 5 inch blade and for 6 to 8, 3-4 inch bladed knives . I want a balance of toughness and edge holding for them.
I send all my knives to Peters, just need a hardness or hardness range.
What should i have them hardened too.
??
I was thinking 60-61HRC but not sure if thats too soft.

Not too soft. I usually do my nitro-v and aeb-l field blades in the 59-60 range.
 
I don’t know how I missed this thread... I’ve been trying to decide if I should try nitro v over aebl but couldn’t find any good reviews of nitro v over the last few weeks. It’s sounding like nitro v will have a little better edge retention? I typically make small edc and hunters so that would be my main benefit.

While Nitro-V is an improvement in corrosion resistance over AEB-L, it is unlikely to have superior edge retention.
 
I’ve been using AEB-L for a couple of years and having PAUL Bos Ht with an RC of 60 , they have held an excellent edge for my Culinary Knives .————-. just had by first batch of blades in Nitro V From PAUL Bos arrive today RC 60... Thanks for everyone’s comments on the Steel

Why?

I'm working on a Nitro V batch.

I know your the aebl expert so I'm curious.

But how? It's got more alloy

Nitro-V is basically AEB-L with a Nitrogen and Vanadium addition. From the thermodynamic calculations it appears that the increased nitrogen leads to less chromium carbide for a slightly reduced volume of carbide. However, even if those calculations are inaccurate the carbide volume would then be unchanged for no improvement in wear resistance. The claim given for an improvement in wear resistance seems to be because of the vanadium addition; however, that amount of vanadium is so small that it is unlikely that any vanadium carbides or nitrides are present after heat treatment.

Thanks brother, I appreciate that.
 
Lattin,
I'm planning a run of kitchen knives made of nitro V. They will be .10 at the spine, hollow grind to .005 at the edge, and sharpened at 10 dps. Would Rc 63 be too hard for them?

I have used AEB-L for a while now. I just started using Nitro-V to try it out. The only difference I am noticing is a slight increase in corrosion resistance.

I don't like to give specific advice for individual applications and knives. I don't know how the knife will be used and I don't have enough data on how that specific geometry behaves. Even if we limited it only to the steel behavior I've never done a set of experiments on NitroV and how its toughness changes with different hardness and heat treating variables. Test it out and let us know!
 
I was under the impression that the higher *achievable RC hardness of RC 63-64 allowed for better "wear resistance" with he Nitro-V. In addition, even at that hardness it was still as stable as the AEBL at RC 62.
...I have yet to test that theory in full. So far the only nitro V I have tried at RC64 was more chippy than AEBL but the blades were bent a bit and it was a new heat treat guy "for me". I do have some Rc 64 nitro V back now from a different heat treater (the same that does my aebl)....so I can test those blades soon.

If advertising was consistent or accurate maybe we could better critique their claims.
