Hello group,

How do you rate Carpenter CTS 204P Alloy versus the other stainless steels, i.e. CPM-S35V etc?

CTS 204P Specs

Thanks

In terms of what?

Looks like another fancy-shmancy powder steel.

I don't think we have any basis for comparing them directly to Crucible products. We'd need the numbers from Charpy tests at two different hardnesses.

Or maybe we could compare if, like, an actual knife were made of this stuff yet.

It will probably not be in any knife I wind up buying. So to me, it's exactly the same as most of the supersteels.

I have not used it but from it's elemental make up it would hold and edge longer than S35VN and not be as tough.

Seems like it would be good for smaller knives that would not be used hard or for kitchen knives that would also not be side stressed.

It is an exact Copy of Crucible 20CV.

It's edge holding should equal that of M-4 but it is also less tough than M-4.

It would have limited application in Sporting knives and no application in fighting or military knives and no real application in Bushcraft knives due to it's lack of toughness.


It also seems to make little sense for Carpenter to copy a steel that was designed and engineered by another American Company (Crucible)

Just my humble opinion.

It tastes better than all the other stainless steels, but AUS8 is a better dancer, and VG10 makes a better apple crisp.

There's M390 from Bohler-Uddeholm, Duratech 20CV from Latrobe and CTS 204P form Carpenter, which is also Micromelt 20-4p. Pretty much the same composition. Makes quite good performer for light cutters.

Mike, do you have source form crucible indicating they make 20CV? I can't find that and if they do make 20CV I'd like to update steel chart to reflect that properly. For now I only have Latrobe and Carpenter from US companies making that steel.

Latrobe is a Crucible distributor and they have it listed with their Crucible stuff.

Thanks Antonio I'm glad it's useful, and upcoming steel chart 3.0 should make search and other things a lot easier, or so I believe.
At least this time I've had consulted possessional UI designers to get some hints.

Mike, thanks, I guess that clears it up.
