personally have a 20CV XM-18 and came across another forum (http://www.jerzeedevil.com/forums/showthread.php?t=71822
) where another one is made of CTS-XHP.

Just found these on the internet:

like to hear what do all you steel experts think of these two based on toughness, wear resistance, corrosion, holding edge, sharpening, etc.
Basically just say whatever you guys know about these two steels and it'll be best if someone have handle both types of steel.
 
In my limited use of 20CV it seems to perform very similar to S30V while being a little easier to sharpen. CTS-XHP is supposed to be a more stain resistant, powdered version of D2. If you have any experience with D2 or S30V that should give you somewhat of an idea of how these steels will perform.

so whats the reason switching to CTS-XHP for those few blades?
 
Looking at the chemistry 20CV should be more wear resistant (therefore harder to sharpen), CTS-XHP might be slightly tougher.
Other that that not much difference.
As usual heat treat can make steel swing either way in any category. For every up, there is a down.
 
I have no current experience with the CTS-XHP but I am on pre-order for two FG Manix 2's in CTS-XHP. HEre is the CTS-XHP data sheet. "Possesses corrosion resistance equivalent to Type 440C stainless but can attain a maximum hardness of 64 HRC, approaching that of D2 tool steel."

Yes I'm saw that on the web as well and am aware of that. But how do you think they will perform in real life? like D2 is reported by some that their corrosion ability is not as satisfactory as S30V, does that mean CTS-XHP most likely be less corrosion proof than S30V?

Because he wants to give his customer options? Maybe you should ask Rick himself.

:pof course I did, & just got reply:)


The last batch of XM-18’s that I did were CTS-XHP. Very similar qualities, the XHP is a little easier to sharpen due to the lack of vanadium.

Got a CTS-XHP XM-18 in the mail the other day..... I'll let you know how it works out.... eventually. I have about a dozen knives waiting to jump into the rotation in front of it ;)
 
CTS-XHP may just turn out to be something I've wanted for some time: a replacement for CPM-D2. I was really sad to see that steel go the way of the dodo.

In any case, I'm very interested in a steel that can come out of left field and capture the attention of people like Hinderer and Dozier.
 
From Mike Stewart of BRK&T:

On Friday I shipped 30 of the XHP Woodlands that we made to see how this steel works with our Heat Treat and Geometry.

I'm pretty sure that you will be able to get one - if you act quickly - from either Dale or Derrick.

Let me tell you about what we learned.

Three of us tested the crap out of mine on Thursday and Friday.

I cut a bunch of wood and leather.

Skittles did the same for about an hour.

jimmy then also did the same and then batoned down two small trees out back for good measure.

Re-read above.

Note that no place did we say we re-touched the edge.

We didn't - I still have not and it still aggressively shaves hair and cleanly slices paper - just like it did when it was first finished.

I'm not sure what is going on with this stuff but I have never seen a more aggressive cutting stainless steel.

Here is what Carpenter Says:

Carpenter Technology Corporation has developed an alloy known as CTS-XHP, an air hardening, high carbon, high chromium, corrosion resistant alloy which can be described as either a high hardness Type 440C stainless steel or a corrosion resistant D2 tool steel. This steel is made using powder metallurgy and possesses corrosion resistance equivalent to Type 440C stainless but can attain a maximum hardness of 64 HRC which is approaching that of D2 tool steel. This alloy offers superior edge retention and surface finish, an ability to be machined to a fine edge, and consistent heat-treatability from lot to lot making it ideal material for knife blades.


I don't agree with them.

This Stuff is nothing like 440C and nothing like D-2.

It grinds easily and polished easily.

It appears tougher than D-2.

440C goes dead flat dull in cutting a fraction of the wood and leather we did so this is more like A-2.

If somebody asked me to put a tag on this stuff - it would be Stainless A-2.

I have more steel than cash on hand so it will be a while before I try the XHP. But it sure looks good on paper!
