Carpenter began producing CTS-204P, and all three versions have been steadily building in popularity with knives ever since. CTS-204P(Carpenter) - Carpenter's equivalent of Bohler-Uddeholm M390 steel and Latrobe Duratech 20CV steel.Slightly more Tungsten(W) 0.65% instead of 0.60% in other two. here. Thickness 10-15% over nominal .150" Thick +.010/.015. CTS-204P is indistinguishable from it in use and 20CV in my use pulls ahead of both. Carpenter CTS-204P is a powder metallurgy stainless steel. 20CV and M390 are shown in the table above for comparison purposes. Carpenter CTS-204P and equivalent steel knives reviews. As an deeper analysis of our Guide to the Best Knife Steel, we’ve compiled the reference table below showing the most popular types of knife steel and their composition of the various chemical elements and compositions.You can click on the column to sort the data according to its feature. Austenitize: Heat rapidly to 2050°-2150°F. Carpenter® CTS® 204P alloy is a highly wear and corrosion resistant, air hardening martensitic cold-work stainless die steel produced using Carpenter’s Micro Melt® powder metallurgy (P/M) process. Composition-wise it's almost a stainless steel. In a carbon-rich alloy like CPM 20CV, the process of austenitization heats the steel until its crystalline structure changes to become austenite instead of ferrite.

It won’t chip, it won’t dull, and unlike ZDP-189, M390 takes an amazing, gleaming high polish and holds it. Pretty much every steel manufacturer makes it and it's quite popular with knifemakers, custom and factory alike. Carpenter CTS-204P is a powder metallurgy stainless steel. As a Powder Metallurgy (PM) tool steel, you get a combination of impressive wear resistance and edge retention plus the added benefit of being highly corrosion resistant due to high levels of chromium. Composition between the two is almost the same. Along with CTS XHP, these include CTS 204P, CTS B70P, CTS B75P, CTS BD1, CTS BD30P, CTS 204P, CTS 20CP, and CTS 40CP. I've used both M390 and CTS-204P, and both perform very very well. Information Pages: As for the manufacturing process, Carpenter's gen 2 process should produce as fine powder as Bohler-Uddeholm's Gen 3 PM does. From here you should be able to crack the code on CTS 20CP and its origin Micro Melt 420-CW. CTS 204p Vs M390 CTS 204p. About the Epoch’s CTS® 204P Steel. This model features a stonewash CTS-204P stainless steel drop point blade and a green aluminum handle with grip inserts, pocket clip, lanyard hole, and glass breaker. Cool to -100 °F, removed from cryo and allow blade to warm to room temperature in cool air. Soak for 30 minutes. Bohler M390 = CTS-204p = CPM-20CV; They're all the same alloy, just from different companies. CPM-20CV is Crucible’s version of Bohler’s popular M390 steel which also influenced Carpenter to copycat with CTS-204P. Condition: New. SBSM Knife Steel Properties Comparison . CTS-204P. CTS 204P and M390 are essentially the same (minor differences, I believe), but one batch could be heat treated differently from another which would account for the greatest difference between them.

Since it is such a high-quality material, many well-known knife makers… Read More » CTS 204p Steel For Knives Review – What Is It? Help & support for the Knife Steel Chart for Android. First, let’s take a look at the more common elements used to manufacture steel. Copyright © 1999-2015 Alpha Knife Supply LLC™ - AKS™. Temper for 2 hours. It is highly wear resistant so it will hold an edge for a long time. I am always glad when people are on the same page as me when it comes to edge geometry over steel composition! There is an email response from a Carpenter employee on the Spyderco forum [5] that provides some information on their powder metallurgy process. Higher austenitizing temperatures maximize edge holding. Bohler M390, CTS-204P, and CPM-20CV are all essentially the same steel and sport a near identical composition. You can click on the column to sort the data accordingly. Simply press the push button, and you're good to go. From my experience with CPM-20cv, it's not even close to as brittle as S90V, easier to sharpen, and hold an edge just about as long. The steel with the highest slicing edge retention has the maximum amount of vanadium carbide and it is heat treated to a high hardness. Not really.
