Is CPM 154 a good knife steel

How Good is CPM 154 Steel?

It is not easy to tell how good blade steel is just by looking at it. And CPM 154 steel blade is no exception. To understand how good steel the CPM 154 is, you'll first need to know its origin, chemical composition, properties, and its comparison to other steels. This information is key to uncovering whether the steel is a good candidate for your knife. Discover more about this steel and its performance in the following in-depth CPM 154 review.

What is CPM 154 Steel?

CMP 154 refers to martensitic stainless steel made by US-based Crucible Industries. Introduced back in 2006, this steel is made using Crucible Particle Metallurgy (CPM) process.

This method results in steel material with a finer grain structure. This process also helps in easy grindability and polishability while improving the steel's corrosion resistance, wear resistance, higher toughness, and better hot-hardness.

What is CPM 154 Steel

CPM 154 shouldn't be confused with 154CM. While both steel grades come from the same manufacturer, Crucible, the 154 exist as the CPM version of the 154CM. In other words, CPM 154 is made using Crucible's CPM process while 154CM falls in the 400 steel series.

CPM  154 steel composition

CPM153 steel composition features high Carbon, chromium, and molybdenum content. This steel combination is the secret to increased corrosion and wear resistance.

The following is the complete list of elements and their corresponding quantities that Crucible Industries uses to create their CPM 154 steel alloy.


Composition (%)



















CPM 154 Steel

1.05% Carbon improves the hardness and corrosion/wear resistance.

14% Chromium enhances edge retention and tensile strength. It also enhances the steel wear resistance and corrosion resistance.

4% Molybdenum increases the steel strength and machinability.

4% Tungsten improves wear resistance and hardness.

0.8% Silicon improves the steel strength.

0.03% Phosphorous adds strength to the steel.

0.03% Sulfur increases machinability.

0.5% Manganese increases the hardness and brittleness of this metal.

CPM 154 steel properties

CPM 154 steel properties

CPM 154 hardness

The CMP 154 hardness is 58-59 HRC, as shown in this datasheet from Crucible. This is a good degree of sharpness and is the same level you're likely to find in quality knives from some top-rated knife brands.

Edge retention

One of the key areas where this steel excels is offering you excellent edge retention. This is expected of the steel grade, given the high chromium levels and Carbon in its composition, which give it high hardness.

Wear resistance

With up to 1% carbon volume, you can rest assured that this steel will offer you great wear resistance.

Corrosion resistance

Chromium is present in CPM 154 in up to 14%, making this steel stainless and corrosion-resistant. While it might not offer you the best anti-corrosion properties than the high-end steels, this Crucible steel will still put a good fight against corrosion.


Sharpening CPM 154 steel is a really hard task owning to its high hardness degree. But the good thing is that it retains a sharp cutting edge for a long period of time, so you only need to do the sharpening task once in a long while.

CPM 154 Steel


This grade of steel offers decent toughness. It has a good hardness that isn't too high, enabling it to balance hardness and toughness.

CPM  154 vs other steels

We came across some questions about this steel, such as "Is 154CM steel better than S30V?" "Is 154cpm better than m390?" and so on. In this section, we'll discuss how steel compares to other popular steels.

CPM  154 steel vs s30v

S30V is equivalent to CPM-154 in hardness, wear resistance, corrosion resistance, and toughness. But s30v offers better edge retention and corrosion resistance than CPM 154.

CPM  154 steel vs 154cm

154cm is another equivalent of CPM 154. It will also offer you relative edge retention, toughness to what you get with CPM 154. However, it has lower corrosion resistance compares to 154CM steel.

CPM  154 steel vs 154cm

CPM  154 steel vs m390      

M390 outperforms CPM 154 with higher edge retention, corrosion resistance, and better toughness. Both grades of steel offer the same level of sharpenability, though.

CPM  154 vs s35vn

S35VN is better than CPM-154 in edge retention, ease of sharpness, corrosion resistance, and toughness.

CPM  154 vs vg10

The Japanese VG10, too, offers you better edge retention, toughness, and corrosion resistance than 154CM steel.

CPM 154 Steel

Is CPM 154 a good knife steel?

The perfect balance of excellent strength, corrosion resistance, and good toughness make CPM 154 a good steel for making knife blades. These key attributes prove that the steel ticks all the boxes for a reliable, high-performance blade. CPM 154 EDC, kitchen, hunting, skinning, and bushcraft knives are great performers.

Is CPM 154 a good knife steel

Don't forget that the knives made from this steel take a fine (crazy sharp!) edge and hold it for really long.

Above all, the knives in CPM 154 come with reasonable pricing. This is probably the reason they've gained more favor among knife users and knife makers alike.
