8Cr13mov VS 440C

Carpenter makes a powder version of 440C in their CTS line. They call it CTS-40CP. One of the knife mags did an article about CTS steels ( XHP) already and Carpenter says another article is coming out about their steels with input from Sal. G., Gayle Bradley, and Bob Dozier. It's the April 2012 edition but it's not available online according to Carpenter. http://www.cartech.com/whatsnew.aspx?id=3684

I didn't know carpenter was doing a powdered 440C, thanks for the info.

Now the question: is 40CP available and is it cost effective.

If 40CP is priced too close to CPM-154, i think that would kinda kill it's place in the knife world.

S60V wasn't created as powdered version of 440C, but as a steel to replace 440C in applications where more wear resistance was need over 440C. They started with 440C as base then modified it to make S60V.

The Chinese have a lot of big industry, I'm sure they have the ability to make higher end steels, but you're not going to see them used in cheaper knives because of time and cost restraints. These lower end steels that you see being used, are being used because they are easier to work with and heat treat.

I know, I can read too. There was a question about "CPM 440c", historically Crucible took 440c and made CPM 440V based off of it, which i guess was their only reason for calling it 440V to begin with and I'm glad that they changed it to S60V given the substantial differences between the steels beyond manufacture-techniques. I assume this was the same rationale behind CPM S90V which was previously called 420V - using 420 as a base? again, glad that they changed the name.

Regarding "high end" Chinese steels, they certainly can/do produce very low-priced competitors to American/Japanese/European/etc. non-powder steels, the next logical step seemed to be attempting to corner the market on this new technology, esp. given the other areas of industry where it is extremely profitable... but they have not? Does anyone know of a Chinese manufacturer that does produce powder-steel for any application and what that steel is called or where to read about it? Americans have Crucible et al., Europeans have Bohler, Japanese have Takefu...

CPM actually is a process as claimed by Crucible. It just so happens to be that they gave a fancy name to a now well known technology.

There is an (R) after "CPM" *shrug* That has since made me wonder if simply their process-name (CPM) is trademarked or if they have a patent on powder-steel technology in the USA especially since the process is so "well known" now...

presz, :thumbup: thank you for compiling that, I was trying to do so in an earlier post but that program always stalls-out the browser on my computer.

Well, there IS quite a variety of closely-performing and closely priced knife-steels, or rather closely-priced knives in a variety of comparably priced steels, so...

I was thinking fixed. I agree about Spyderco native...I gave one to my son.

What about Spyderco Mules?
 
You see the trademark symbol because Crucible trademarks their steel names. Take S90V for example, that name is owned by crucible. Other foundries can make the steel, but they can't legally call it S90V.

i can read Chinese, according to some people in a chinese knife forum "http://tieba.baidu.com/f?kz=840718708", some China factories product "FWT15,FW72,HIP,PHD,GFT1,GFM2, FW10Mo5Cr4V2Co8, S590 l" these powder-steel high speed steel. i m not a pro of knife nor steel, so i m not sure if these steels are the steels that u r asking for. for example s590 is a Chinese version of Bohler, and this company will sell them "http://www.tiedao-mold.com/products/detail/343.html"
 
I have a steel problem... I want to get a hold of that tiedao now to do some testing

do I need to contact a doctor?

(sorry I know this is also extreme thread necro)

I certainly agree. I saw this thread up on the GKD list and started reading before I realized how stale it was. I even liked a couple responses to a rather rude poster who's made a whopping 41 entries over the last 10 years. Quite a waste of time, although a quick scan of a few of Mr Rude's other posts let me know that his response here was not out of character. Now I know there's someone else I can skip over. :D
