Kizer Original Folding EDC Knife, 154CM Steel Blade, Grey Aluminum Handle, 3 Inch Pocket Knife for Everyday Carry, V3605E3

Product Information

There are also bonus points if the steel can be sharpened with cheap abrasives. As budget-minded buyers probably also look for budget sharpening stones. In many ways, the chemical composition of 154CM steel is similar to 440C steel. The main difference between these types of steel is the addition of molybdenum in the 154CM variety. What Are 154CM Steel Properties?

Powder metallurgy is a technology designed to maintain a small carbide size. Read more about how it works here. It is most useful for steels with large amounts of carbide but also helps to be able to add certain carbide types. Vanadium carbides are very large with conventional production of steels but are very small with powder metallurgy. With conventional steels this limited vanadium additions to about 4-5%, and this was greatly expanded when powder metallurgy was developed. The biggest change that is seen with powder metallurgy in measured properties is in regards to toughness. Below shows a comparison of carbide structure between D2 and CPM-D2, and then toughness measurements between the conventional and PM versions of CruWear, D2, and 154CM. steel was developed in the United States by Crucible Industries in 1959. The company is renowned for producing high-end steel for aerospace, automotive, and industrial applications.

Manganese Mn 0.50%: improves the strength and hardness of steel. When the steel is heat treated, hardenability is improved with increased manganese. is a PM steel and is much more fine-grained than S30V. This results in its ability to hold a fine edge longer than S30V which, due to its high carbide volume, is coarser grain steel. However, the coarseness of S30V means that it has an excellent “toothy” edge and will maintain useful sharpness as a utility knife for longer.

Vanax and LC200N are unique in reaching 59-60 Rc while being very stain resistant. H1 and 420 also have excellent corrosion resistance but are limited to lower hardness and edge retention. The “S” stands for the powder steel-making process used. The addition of vanadium and niobium along with higher carbon and chromium elevated S30V’s hardness, strength, and wear resistance above 154CM.Here is a big table of steels so that you can see the compositions of many of the steels that will be discussed in this article. This chart has both too many and too few steels in it as I’m sure other steels will be brought up but I also have several steels listed that I will not be seriously considering. Some of these steels are available as either a PM or ingot version and I am of course only considering the less expensive ingot version. So CruWear is conventional CruWear not CPM CruWear.

To simplify this, we will undertake a comprehensive comparison between two prevalent knife steel types: 154CM and Crucible Particle Metallurgy’s S35VN (CPM S35VN).
