Scaling 20CV VS S90V Stainless Steel – Which One is Better?

Last Updated: June 10th, 2022

You have needed a stainless steel blade to get a motion in your daily life. That will provide you with the best support to continue your regular cutting experience. If you are confused about the 20CV VS S90V stainless steel blade, you will clear it here.

The main differences between 20CV and S90V stainless are that the 20CV’s toughness is better than S90V, but edge retention, wear, and corrosion resistance are less than the S90V. The 20CV is introduced with the most extensive chromium and vanadium carbide range. However, the S90V is also furnished with carbon and vanadium for wear resistance.

The producing formula is about the same, but they are different in their chemical components. To learn the key differences between 20CV and S90V, continue scrolling.

Comparison Table: 20CV VS S90V

Category 20CV S90V
Making Process Crucible Particle Metallurgy Same
Ingredients Vanadium Carbide & Chromium Vanadium & carbon
Toughness More Less
Edge Retention Better Best
Corrosion Resistance Lower Higher
Wear Resistance Good Better

What Is 20CV?

The 20CV stainless steel is introduced with Crucible Particle Metallurgy. Here is used the most considerable amount of chromium is to increase its toughness. This stainless steel is also presented with vanadium carbide, which is essential for improving edge retention and sharpness. 

This stainless steel becomes more wear and corrosion resistant to its high volume of vanadium and other chemical components, perfect mixing.

In 20CV, you get some exclusive features that will make this stainless steel better than the others. It even provides long-time performance with good sharpness. Let’s check some exclusive features of 20CV.

Exclusive Features

  • High-making process
  • Perform in all weather conditions
  • Rust wouldn’t attack
  • Keep sharpening a long time
  • Free use shape & structure

What Is S90V?

The S90V stainless steel is also made with Crucible Particle Metallurgy standard. So, there is one option to damage the steel strength. The S90V is introduced with high vanadium and a mix of carbon that increases the steel’s durability for a long time.

The carbon makes the steel sharper, and the vanadium is responsible for expanding the edge stability. It even protects against wear and corrosion to keep the brightness in steel alloy.

In S90V, you get some unique features that make stainless steel more popular in the market. This steel knife provides the best support for rough use and regular movement. Let’s check the S90V’s unique features.

Special Features

  • Making Process Is Standard
  • Durable Structure
  • Good toughness
  • Better wear & Corrosion resistance
  • Usable for rough use
  • Bright Knife blade

Key Differences & Similarities Between 20CV & S90V

After seeing the comparison table and the summary of 20CV & S90V, you get an overview of these two stainless sheets of steel. To learn in detail, let’s briefly check the main differences & similarities.

Making Process

Both CPM 20Cv and S90V are made with Crucible Particle Metallurgy with the standard powder metallurgy formulation. To increase the strength and durability of these two stainless sheets of steel, the Crucible industries play an influential role.

This making process makes these premium steel higher than the other knife blades. It even influences performance against rust or other harmful elements and keeps the structure in the correct format for easy use.


In 20CV, a vast amount of vanadium carbide was added and chromium to increase the hardened flexibility. Here has a perfect mixing of chemical components for high resistance.

On the other hand, the CPM S90V is introduced with a high amount of vanadium and carbon-like CPM S110V steel, which is also responsible for increasing the sharpness of the knife blade HQ and keeping it for long.


The 20CV’s toughness is better than the other super steel. It offers higher toughness to perform in all conditions like CPM M4 and is never displaced from its position.

Wherever the S90V is not tougher than the 20CV stainless steel, here used carbon, which would make it more flexible, not hardened, or tougher. So here, the toughness is a little bit lower.

Edge Retention

The 20CV’s edge retention is better than CPM S30V for its perfect mixing of vanadium and chromium. But its hardness is not more than the other blade steel. For regular use, the edge retention is good enough to continue.

On the other hand, the CPM S90V steel has the most edge retention. It can perform well for rough uses and all conditions for its edge retention length. According to the edge retention scale, it will keep high edge retention even in a folding knife like M390 steel.

Corrosion Resistance

The CPM-20CV offers you a high corrosion resistance feature to make a protection shield against corrosion and rust like cold steel. Pollution can damage your knife blade quickly, but corrosion has no chance of attacking this Damascus steel.

However, the S90V knifemaker offers you the best corrosion resistance than 20CV stainless steel. Its corrosion resistance is good enough to keep your S90V knife blade fit and performing for a long time.

Wear Resistance

The 20CV is responsible for protecting wear and harmful elements or oxidization. When using the knife blade in water or other fluid, there arises a chance to wear damage, but this blade provides resistance support.

On the other hand, the S90V is also more responsive to high wear resistance and retains its best protection. So if you choose this stainless steel knife blade, you get sound performance in water and soap uses.

What Will Be The Best For You?

According to the extensive discussion, we can say both CPM 20CV and S90V perform well. If you need a tougher blade, 20CV will be the best option.

On the other hand, if you are fond of extreme edge retention, better toughness, wear, and corrosion resistance, then S90V will be the best option. The choice is entirely dependent on your demand.

But we will recommend using the S90V stainless steel knife blade for durability and flexibility. You even get more edge retention with the best wear and corrosion resistance features here.

People Often Ask

Is It Easy To Sharpe 20CV?

Yes, it’s easy to sharpen quickly. If you use Spyderco stone to make 20CV points, then it will be too easy. Starting with medium grit, you can switch well and finish coherently. You even make it sharp with any stone or cement surfaces.

Which Is Better Between S90V & S30V?

According to edge retention and short duration, S90V is better than S30V. Though the S30V is easy to sharpen, the durability is temporary. On the other hand, it’s a little tough to point at the S90V but durable for a long time.

Is S90V The Best Knife Steel Ever?

According to the CATRA test, we get high vanadium and 14% chromium carbide in S90V and S125V. The wear resistance and edge resistance are better than the other steel. So, in that case, we can say S90V and S125V are the best stainless steel.

Is 20CV Comparable To Others?

Yes, the 20CV is comparable with Carpenter’s CTS-204P or Bohler’s M390 stainless steel. Here you get a mirror finished blade with better sharpness.

So if you want to compare with more relevant stainless steel with 20CV, CTS-204P and Bohler’s M390 stainless steel can be the best option.


Hopefully, you get a clear concept of the 20CV VS S90V with their specific criteria. Now it’s easy to choose the best one. Both play the same role in each position, and their purpose is the same. According to your needs, you can choose any one from them without hesitation and enjoy the best service for a long time.

20CV is more rigid stainless steel than the S90V blade. So, if you want a tougher blade, 20CV can be the best option. On the other hand, for wear and better corrosion resistance, and better edge retention, you can choose S90V.

If you still have any confusion, reread the content with full attention. You even take help from an expert closely related to the stainless steel knife industry to reach the final decision.
