CTS-XHP vs m390

Jim, didn't they specifically angle for more toughness than your typical PM stainless with the CTS-XHP? Carpenter says it is like "stainless D2" but I have heard that Mike Stewart describe it as being closer to a "stainless A2' because it appears to have a fair bit more toughness than D2.

Didn't Dozier call it a 440C on steroids or something? Someone said it. Sept. 2010 Tactical knives maybe?

Carpenter states:
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. Possesses corrosion resistance equivalent to Type 440C stainless but can attain a maximum hardness of 64 HRC, approaching that of D2 tool steel. Now available in strip product form.

That really depends on both what one is sharpening with and the Heat Treating and tempering process of the steels in question as that will vary.

The difference in Striders S30V and say Spydercos is noticeable on the knives I have delt with from both companies and then compare both of those to CRK's S30V.

I wasn't talking about being able to feel the difference at all, of course you can feel the difference.


The point of my post was summed up in the last sentence.


Steels with great edge retention don't always equal "hard to sharpen."

I agree with you Jim. I can tell the difference between two spydercos in S30V. One has a black blade, one satin but they definitely feel different on the DMT's. Not what I'd call difficult at all, but they feel different.

Of course I can tell the difference between 1095 at low 50's ( Case CV) and slightly less low 1095 in GEC's :)

D2 ( queen at 57) feels very different than , say, Benchmades D2 at ? ( Supposed to be 60-62)

I suppose I can tell because I'm doing them one after another, not days or weeks later, but I sure can tell.

Joe,

It's crazy how really noticeable the differences can really be I think. :)

CTS-XHP -1.60 C, 0.50 Mn, 0.40 Si, 16.00 Cr, 0.35 Ni, 0.80 Mo, 0.45 V

ELMAX - (C) 1.70 (Cr) 18.00 (Mn) 0.30 (Mo) 1.00 (Si) 0.80 (V) 3.00


Surprised by the result.
I ever thought from this data that ELMAX would have more wear resistance than XHP due to higher C and V.

It's the Cr, Mn, Mo and V are the Carbide former's and then with 1.7% Carbon.
 
Well it would be spydercos m390 and xhp since im shopping for a sprint run para 2. The only s30v I have is a bos ht vantage pro, which is not fun to sharpen at all.
 
The XHP is about $50 or so cheaper than the M390 when it comes to Spydies! If that matters to you.
 
Price really doesnt matter cause which ever i get its just for fun cause my vantage will do anything either of these would. Just want a new toy with some really cool steel

Not anymore. The xhp para 2s have been going for $200+ on the forums. M390 para2s can still be purchased from the supplier for about $185.

Jim, the .35% nickel in the XHP is interesting. Obviously, it is a lot less than the toughness imparting 1.5-2% you see in L6 and 15N20, but it makes you wonder what effect it has? I may be wrong on this, but I got the impression that people think that nickel and high carbon content don't mix well in stainless steel and that is why it is so hard, if not impossible to find a medium to high carbon martensitic stainless steel that has enough nickel to give you your shiny silver layers in stainless damascus.

I think it there for grain refinement and maybe stain resistance.
 
Hands down, M390 is the best steel I have ever used and sharpened. It just works.

Just thought I would ask you..you seem to know your stuff...thx for the link..
 
For you guys that know all the makers - who makes a M390 folder , straight handle , 3.5" blade ?? I can't stand a curved handle so Sebenza and similar is what I need .
 
my hinderer fieldtac is in CTS-XHP and it is a very hard steel and takes more strokes to sharpen. that being said, it holds an edge forever.
