It most certainly gives you a better edge retention than normal cutlery or stainless steels. Don’t confuse CPM 154 with 154 CM steel, CPM154 is a developed version of the 154CM Steel, benefiting from the CPM process of @Crucible, many costume knife maker finds their ease in using the CPM 154 Steel thanks to it balance properties, which attracted my intention. Proven carbon and tool steels, including 1095, A2, O1, and D2 are in the mix, joined by the newer CPM-M4. The blade is gray-coated CPM-M4 that is extremely sharp and durable. CPM-154 Heat Treatments. Molybdenum is added with vanadium and tungsten and a ton of carbon to create a knife with a hardness level that exceeds S30V and S35VN, coming in at up to 65HRC. ... CPM-M4 and S90V the difference is simply brutal. CPM M4. It has a Reverse Tanto shape for a good piercing tip and is 3.98″ (10.11cm) in length. It is treated to a very hard 62-64 HRC, however, so sharpening is going to be more time-consuming. Therefore I decide to make a CPM 154 Steel Review. Further parsing of the data. Many custom knifemakers still preach by 440C simply because it's a pretty easy steel to work with, and it takes the BEST finish among all stainless steels hands down. ... CPM-M4. Blade materials are those used to make the blade of a knife or other simple edged hand tool or weapon, such as a hatchet or sword.. American made stainless steel with well-rounded characteristics including good edge retention, overall toughness, and corrosion resistance. CPM M4 will even out wear M42 in applications where red hardness is not the controlling property. Now CPM 154cm and other engineered steel s30v, bg 42, and others are a different story. Crucible: CPM-M4, CPM-3V, CPM-4V Generic: A2, O1, D2, 1095. In applications where it has been traditionally necessary to use a high cobalt material for red hardness, e.g. CPM M4 is a little different. 154CM is a very high carbon stainless steel with the addition of Molybdenum. In the CPM-154/154CM CATRA article we compared cryo vs non-cryo and no difference was found, but that was with high temperature tempering (~1000°F) which some claim does not result in an improvement from cryo. Advantages: Relative toughness, wear resistance. The thickness of the blade is .156″ (3.96mm). M42, upgrading can be accomplished by progressing from M42 to CPM Rex 20, CPM Rex 45, CPM Rex 54, CPM T15, CPM Rex 76 or CPM Rex 121. 154CM. I recently did a range of experiments heat treating CPM-154 to learn more about its optimal heat treatment. Certainly nothing to the extent of 3x or 6.5x improvements in wear resistance. The blade of a knife can be made from a variety of materials, the most common being carbon steel, stainless steel, tool steel and alloy steel.Other less-common materials used in knife blades include: cobalt and titanium alloys, ceramics, … What it is: CPM M4 is a "Crucible Particle Metallurgy" carbon tool steel, widely regarded as a "super steel" for its properties and performance. CPM-154 is known for its ease in finishing combined with good all-around properties including good potential hardness, edge retention, and toughness. Disadvantages: Relatively more difficult to sharpen than CPM 3V and predecessor tool steels like A2, not as tough as CPM 3V or CPM 4V. ... VG-10, N690, CPM-154 and 154CM are finding their way into a lot of moderate priced knives, and even some budget items. American powdered steel is the toughest available.
