Anybody here use CPM 1V?

I saw in Blade that Dan Farr is using it some, so I looked it up on Crucibles website, and thought it looked interesting. So I just bought a chunk from Crucible. The toughness is about the same as CPM 3V. But it only has .55 % carbon, so it seems like it might be a little on the "weak" side.

i was wandering the same thing when i read that
cpm3v does a good job of being strong im not sure what i would would need 1v for
maybe the 1v is better to forge i dont do that (yet)
i may try to forge some of my 3v just to see how it works
hey dek you ready to show me the ropes

It's tougher than 3V, and it has wear resistance around that of A2.

It's a steel for people who either find 3V too hard to grind, too hard to forge, too hard to sharpen, or not tough enough (though the last is unlikely).

grinding it soft is easy(3v) but then again i can only base that on Vs SS 440c ats34 and cpm154 im working with some 10V now thats some fun grinding there more so with my 1x42
i ll let you know how i feel about forging it
and as far as toughness i know you can beat the hell out of 3v

It's pretty expensive. I bought round stock, which is probably the cheapest way to get it, and it was $11.47 per pound.

I remember Jerry Hossom made a blade from 1V, and found that it suffered from plastic deformation at high hardnesses when subjected to edge impacts. Perhaps he'll see this thread and chime in, or drop him an email for details.

That's what I would expect with the low carbon content. Seems to me after the vanadium sucks up carbon you'd end up with a lot of pro-eutectoid ferrite and not much martensite.

It reaches 60 Rc, there better be some martensite in there.

There's definitely some. It doesn't take that much carbon to make steel hard.
1045 will get close to 60 RC.
I think 60 is the as quenched hardness of 1V. If that's true, then the resistance to deformation of 1V might be similar to 1045. I hope I'm wrong. We'll see.
