So is all 154CM made by Crucible ? I know that all S30V is made by Crucible so I was wondering if the same goes for 154CM (?)
 
I'm no expert. .but since I thought the cm part stood for crucible materials...it would be odd for another steel producer to make a similar steel and not change the name. Hence 154cm i would think would be crucible only. I Could be very wrong though.

I thought the same thing. But since I am far from being an expert myself , I figured I'd ask here and hope that a steel expert would chime in and educate me a bit.
 
There are other steels that are the same, but have different designations for the other companies. If I remember correctly, ATS-34 is one designation for another company's branding of the same steel.

What I'm trying to say is that you can get the same steel from other companies, they just won't call it 154CM.

154 CM®/CPM® 154
154 CM is a high molybdenum modification of 440C offering improved wear resistance (edge retention) and better corrosion resistance. It is also available in a CPM version for improved toughness and polishability.

Believe the CM stands for chrome molybdenum

Do you have a source? I couldn't find anything about it on Crucible's website. I'm just curious because chrome moly steels usually have much lower levels of chromium than 154CM has, and they normally aren't stainless.

Just a guess. It's how a lot of their other steels are named. Like the ' is S30v being for vanadium.
 
I believe it was Latrobe that was making 14/4 ChMo which is 14% chrome and 4% moly. It's the same as 154cm. Now Carpenter owns both Latrobe and Crucible I doubt they will have more than one version competing with themselves.
 
Mastiff and RamZar , thanks for the info.

This is why I like this forum so much. Every time I log in I learn so much about the hobby which I love. I had no idea that Carpenter owned Crucible. I thought that they were bitter rivals. I can see I still have much to learn. And that steel chart is great. Thanks.

And just to avoid any confusion on my side , all 154CM is definitely made by Crucible , right ? I'm just double checking because it does not say "CPM 154CM" on my Spyderco Manix2. It just says "154CM".
 
Yep, If it says 154cm it is Crucible.

The originam CM stood for Climax Molybendum, the company that originally developed the steel before Crucible made it. They were/are a Moly mining company that developed uses for moly, such as: http://www.climaxmolybdenum.com/aboutus/companyinformation/history.htm
The metal immediately found use
as a replacement for tungsten in some metallurgical applications. The primary use was in Allied efforts at producing armor plating and large gun barrels during World War I. With the end of the war, the uses for molybdenum momentarily disappeared and the company shut down. After restarting in 1920, Climax developed markets for molybdenum in both metallurgical and chemical applications.

So, there it is. CM isn't crucible molybendum or similar as thought. It is Climax Molybendum who was promoting uses for it's Moly. Crucible itself has a large history and was very active in making Armor plate in WW2, as well as many other things. It was, as we know, active in the development and production of some of our more familiar powder steels.

Do you have a link to this? All I could find was Carpenter buying up small pieces of Crucible.

ATS-34 is made by Hitachi and is the same steel.

Thank you very much for this little nugget of info, I was driving myself crazy wondering about the CM :rolleyes:

I knew it was the same steel, didn't know it was Hitachi's. Thanks for the info :)

There is no steel labeled CPM-154CM. There is CPM-154, which has the same composition as 154CM but is made using Crucible's power steel technology, and there is 154CM, which is an ingot steel. :)
