S30v Vs 154cm: Which Knife Is Best?

Choosing the right steel for a knife is really a tricky task because each material comes with some pros and cons. Not any steel is perfect in every parameter.

Today we are going to discuss two very popular steel types namely S30V and 154CM.

Let’s understand what we are going to cover in this article about these two steel types:

  • Brief history and origin of the steel.
  • What they are?
  • Chemical composition.
  • Hardness
  • Edge retention property.
  • Uses

So without further ado…

Let’s walk you through this detailed guide about 154cm and S30v.

Does S30v Stainless Steel Good For Knife?

S30v steel also known as CPM S30v is high-end steel. This is a powder-made martensitic (harden) steel developed with the collaboration of the two most famous knife makers Dick Barber and Chris Reeve.

S30v is made of Martensitic steel which is highly worn and corrosion-resistant. It has a high percentage of carbon, and a defined ratio of Molybdenum, and Vanadium. Steel is used to manufacture pockets knives and is also a very popular material to manufacture kitchen cutlery.

This is a very popular and reputed steel type for making the blade of steel knives even though it covers most of the steel-based tools market in America.

CPM S30v Or S30v Chemical Composition

S30v is made of a combination of different components, one of them is Corbon. Carbon is known to improve the hardness of steel and it also makes steel wear and corrosion resistance. But it will reduce the strength of the steel if added in excess quantity. The carbon percentage in CPM S30v steel is 1.45%.

Nobody wants that the knife he is using loses its edge retention again and again and needs frequent sharpening. A chemical substance namely Chromium improves the strength and edge retention property of the steel and is also known for improving wear and tear resistivity of the knife. The Chromium percentage in S30v is 14%.

The Main Chemical Components In S30v

CarbonChromiumVanadiumMolybdenum
1.45%14%4%2%

Other chemical substances which are used to improve the strength of the steel and are used in S30v: Nitrogen 0.2%, Silicon 0.5%, and Phosphorus 0.3%.

To improve the machinability of the steel some other chemicals are used. Here I’ve mentioned the percentage of these chemical components in S30v which are Molybdenum 2%, and Sulfer 0.3%.

To improve the hardness and bitterness Manganese 0.5%, Vanadium 4%, and Tungsten 0.4% are mixed in the S30v.

Advantages Of Using A Knife Based On S30v

  • Highly corrosion and wear resistance.
  • The knives made with S30v are equal to or sometimes tougher than the 440C and D2.
  • Doesn’t need frequent sharpening.
  • The S30v knives come with excellent edge retention property.

Does 154CM Good For Knife?

154cm has been high-end steel for a long ago. 154cm steel is one of the best materials for knife manufacturing which is manufactured in the USA by Crucible Industry. 154cm is a modified form of 440c which is Martensitic stainless steel.

The formation of 154cm is started with the addition of Molybdenum in 440c. The steel was developed in 1970 and used to make Jet engine turbine components at that time.

The steel is known for its hardness, and wear resistivity and enhances the corrosion resistivity as well. Unlike S30v, this is not a kind of steel made with powder steel. Now steel is very popular to manufacture cutlery and knife blades.

154cm Chemical Composition

154cm is made of a combination of different components, one of them is Carbon. Carbon is known to improve the hardness of steel and it also makes steel wear and corrosion resistance. But it will reduce the strength of the steel if added in excess quantity. The carbon percentage in 154cm steel is 1.05%.

Nobody wants that the knife which he is using loses its edge retention again and again and needs frequent sharpening. A chemical substance namely Chromium improves the strength and edge retention property of the steel and is also known for improving the wear and tear resistivity of the knife. The Chromium percentage in 154cm is 14%.

Other chemical substances which are used to improve the strength of the steel and are used in 154cm: Silicon 0.30%, and phosphorus 0.03%.

To improve the machinability of the steel some other chemicals are used. Here I’ve mentioned the percentage of these chemical components in 154cm which is Molybdenum 4%, and Sulfer 0.03%.

To improve the hardness and bitterness Manganese 0.5%, Vanadium 4%, Tungsten 0.4% are mixed in the 154cm.

Advantages Of Using 154cm Based Knife

  • Its HRC value is between 58 and 61 which makes it harder steel than other stainless steel varieties.
  • It can retain its sharpness for a longer time.
  • It is less expensive than the other most popular steel types.
  • This is a type of steel used in survival knives.

154cm Vs. S30v: Specification

Type Of Steel

S30v is a byproduct of metallurgy powder. The powder consists the melted alloy particles. On the other hand, 154cm is not a powder steel (its other variant CPM154 would be a powder variant), but it is a commonly used steed that is common in some higher-grade knives.

Chemical composition of S30v and 154cm

Hardness Comparison

The hardness level of s30v according to Rockwell Hardness is between 58 and 61 HRC and 154cm hardness relay between 60 and 61 HRC.

Some tests have proved that S30v is a harder steel type as compared to the 154cm. The hardness of S30v depends on the combination of Tungsten, Vanadium, Manganese, and carbon.

On the other hand, 154cm has a combination of Chromium, Carbon, and Manganese which provide it with excellent hardness.

Edge Retention Comparison

The edge retention depends on the hardness of the steel as we have seen the hardness of S30v and 154cm is very close, which means both the steels come with excellent Edge Retention.

Wear Resistance Comparison

Although 154cm is very hard steel and has decent wear resistance properties, S30v has a high amount of Vanadium and Chromium which make it slightly better than 154cm in terms of wear resistivity.

Sharpness

S30v is hard steel as compared to 154cm which makes it a bit difficult to sharpen but it doesn’t require frequent sharpening.

On the other hand, 154cm is easier to sharpen but it requires frequent sharpening.

Toughness

S30v is hard steel which impacts its toughness. It has better hardness and corrosion resistivity but its toughness is not the same.

On the other hand, 154cm has decent toughness than the S30v. It has a proper balance between hardness and corrosion resistivity.

The above result is only for comparison purposes, it doesn’t mean S30v is bad steel in terms of toughness. Its toughness is excellent.

Does s30v and 154cm Steels Rust?

Every stainless steel will rust if it is not taken care of properly. S30v and 154cm both have 14% of chromium which provides great corrosion resistivity to them.

Note: If you want to use your knife for a longer time without rusting then after using it just wipe with a dry cloth will extend its life and prevent any rusting.

Which One Is Best Between S30v And 154cm?

Having a sharp, durable, and long-lasting knife could be a life savior for some tough situations. If you are still in confusion about which steel type is highly durable, sharp, and tough between s30v and 154cm then let’s understand them in a nutshell.

154cm has a fine edge and has more fine-grain. Its edge remains fine for a longer period of time than the S30v. S30v has a coarser grain toothy edge rather and its edge is also remain sharp for a longer period of time but not as much as you will get in 154cm.

S30v has excellent wear resistivity but 154cm has excellent toughness. 154cm takes very less time in sharpening than the s30v, but you have to sharpen it frequently.

S30v is tough steel and takes more time in sharpening than the 154cm. S30v steel knife is more suitable for the humid environment and a little bit more expensive than the 154cm.

I personally recommend going with S30v because it is made using new technology. 154cm is older than s30v this is also a great steel type but new and advanced technology offers more advantages than the older one.
