Im thinking of trying some nitro v

I know it is supposed to be very tough and very stainless. How does is rank in the edge retention category. I know that it is basically AEB-L with a little nitrogen and vanadium

One source speculated that edge retention should be about the same as AEB-L, another source that tested the steel showed an impressive result showing higher edge retention than many popular steels including s35vn, Cpm 154, d2, 3v ect. That test only tested one knife in nitro v vs many in the other steels

For you guys that have worked with nitro v if heat treated to the same HRC say 60 or 61 and with identical blade and edge geometry how will it preform in edge holding compared to say s35vn or cpm154 or D2? Hold an edge longer, shorter, about the same? These are steels that I'm fairly familiar with.

Thanks
 
I have worked with both AEB-L and Nitro V. I heat treat them both to RC62. I like them both however I haven't found any discernible difference in performance between the two.
I still have both in stock and will use up what I have but I personally can't justify the extra expense of Nitro V at this time.

Cutting edge retention in controlled slice cut testing will be less than S35VN, CPM 154, D2.
Wear resistance may be a little higher than AEB-L.

Toughness and stability will be higher than
S35VN, CPM154, D2.

So in real world, the advantage is going thinner and harder to make up the difference yet will still not be a wear resistant steel
 
Wear resistance can only go so far with hardness alone. Great geometry helps a lot. For higher wear resistance, you need carbides (or nitrides, in some circumstances), and not all carbides are the same hardness. Iron carbides are the softest. Vanadium and tungsten are harder. Higher carbide volume = increased wear resistance. At a certain pint, increasing carbide volume gets too high for certain applications, like fine slicers. Going higher carbide than z-wear/V4e/M4 results in losing fine edge stability. In stainless, s35vn, or vanax seems to be the point of max carbide/nitride for fine slicers.

My last order of blades I had water jetted was Nitro V instead of AEB-L.. While I feel there was perhaps a slight increase in edge retention I basically agree with Robert that the increase in cost over AEB-L isn’t justified and my next run of my Culinary blanks will be AEB-L.. I have them HTed to 60-61 BTW..
