Are the days of the S30V Military Numbered

The Military is made in Golden, CO. I doubt we'll see a VG-10 version.
We had better not. :mad:

I would really not like a VG-10 version.

My picks for a replacement steel would be 154CM or 52100. Let's try some carbon stuff. :D

I hope whomever buys Crucible keeps the specialty steels around. This is distressing news. :(

Spyderco does use N690Co which is more or less the same as VG-10.
 
I think Spyderco should buy Crucible's recipe for S30V (and S90V, I'm more distressed to see that one go), and then have another foundry produce it.
 
I thought the CM in 154CM stood for chrome moly. If my memory is correct, I thought I read an article where Delevan said Crucible was going to produce 154CM in powder metal technology...CPM154.

Maybe so, but somewhere it was said it was for Crucible Metals(Materials? wish I could remember where I saw this) IIRC, it was developed in the 50's as a modified 440C, dropping some chromium and replacing it with molybdenum, for increased hot hardness since it is a jet turbine material.

They do produce a CPM154 version of 154CM, though I don't know if 154CM was a creation of Crucible's or not.
 
154CM, D2, and a lot of other steels were around before Crucible started making these steels with their powder metal technology. Same recipe...different and better way of making these steels.

D2 is WW2 era steel, even though a similar composition has been used even before then.
 
I am not very knowledgeable about steels, do other foundries make steels using powder metal technology? or was this a Crucible exclusive method?

It's a shame what happened there. I'm sure everyone there was sad to lose a co-worker and on top of that some hard-working Americans are going to be looking for jobs.

I know Hitachi uses a similar process to make ZDP-189. I'm not sure it's "exclusive", but they do have it down to a science.
 
Here's an answer from another thread. This sounds about right to me.

154CM was named when it was developed by Climax, so it is unlikely CM standards for Crucible. It more likely stands for Climax Metallurgical or Chromium Molybdenum, since it's not much of a stretch to think the original composition may have had 15% chromium.

Several foundries do, they also have steels of pretty much the same alloy content to boot. Actually, Bohler-Uddeholm is in like the third generation of powdered metal technology.

Ah, Climax, not Crucible, my bad. Knew it was something about the company name, just forgot which one. About the only thing you can count on is if it isn't an AISI designation or equivalent, someone own/ed the name, and someone else probably makes the same thing under a different one.
 
I'm not worried about S30V, never cared for it much anyway.

What I am worried about is S110V, CPM M-4, and any other alloys that were in development.
Over the past ten years we've seen some of the most insane alloy types introduced that only recently did the will (patience to grind) and popularity exist to put it in knives.
Now one of, if not the pioneer of that trend is getting chopped up!

I was just starting to look forward to a mass produced NiTiNOL...

Hopefully someone else will pick up the slack, but I'm not holding my breath.
 
don't worry to much about PM-M4, Carpenter has micro-melt M4, Latrobe has DuraTech M4, and Bohler has S693.
 
I wish WISH that Spyderco would make a H1 Millie or Para.

Yellow handles please;)
