What is S30V Steel?

Table of Contents

When looking at superior knives made in the US, you will see that S30V steel is one of the most common steels for knives blades. S30V steel is made with chrome and carbon content, and from different tests, S30V offers edge retention as well as corrosion resistance. 

What is S30V Steel?

S30V steel is a kind of steep is made by Crucible Industries. Today, there have been developments to come up with the best mixture of wear resistance, hardest as well as corrosion-resistant steel and the S30V powder steel is a result of which effort. 

If you’re in the market for the best folding knife, pocket knife made from the best and high-grade stainless steel, think of S30V steel varieties. Knife blades made from S30V steel have proven to be very effective and corrosion-resistant. 

Not like conventional rotated steels, this S30V is created following powder metallurgy- a procedure that lessens molten alloys to powder. Then the grains are firmly pressed mutually to make superior powdered steel with superb stability and toughness. 

Chemical Composition of S30V Steel 

  • 1.45% Carbon C: Improves the hardness, tensile strength, and edge retention. It also boosts steel resistance to abrasion, wears as well as corrosion. 
  • 14.00% Chromium Cr: Over 11 percent of Chromium is what makes stainless steel. Chromium carbide formation increases the knife blade’s tensile strength, toughness, and hardness. 
  • 2.00% Molybdenum: This property enhances hardness and machinability. 
  • 4.00% Vanadium V: Improve toughness and wear resistance and increase rust resistance. The high content of vanadium allows VR formation, providing the steel an advantage over other types that depend on Chromium in wear and tear resistance.
  • 0.20% Nitrogen N: This adds durability to the knife blade, works the same way as carbon in the alloy. 
  • 0.40% Tungsten W: Boosts hardness and wear resistance, largely included to tool steel.
  • 0.50% Manganese Mn: Improves brittleness and hardness. 
  • 1.00% Silicon Si: Increases heat resistance and strength 
  • 0.03% Sulfur: Enhances machinability
  • Phosphorus: Improves hardness and machinability. 

What are the Benefits of S30V?

S30V steel offers many benefits such as:


Hardness in the blade is the ability or strength to resist malformation when utilized in hard applications. This kind of steel has 58-61 HRC Rockwell Hardness. But, with additional heat treatment, high carbon steel is able to reach up to 64 HRC. The high hardness is what makes this the best and top stainless steel available today. 

Edge retention

Because of its amazing hardness, knife blades made from this steel provide superb edge retention. The fact that it is made from highly uniform molecules of Tungsten Carbon, Manganese, and Vanadium, this steel makes a knife that can retain sharpness for many years of use. To get rid of the aggravation of sharpening a knife after some cuts, get yourself a product made from S30V steel. 

Corrosion Resistance

Buying a knife that is corrosion resistant provides you remarkable protection against rust, particularly when exposed to acids, moisture, and salt. S30V steel has a high amount of Chromium, providing superb corrosion resistance. On the other hand, just like a knife made from other forms of steel, and S30V steel knife shouldn’t be taken for granted, or else it will rust.

Wear resistance

Because of the high amount of Chromium and Vanadium in the composition, this steel is included in the list of the best steels with high wear resistance. Knives made from S30V have proven resistant to damage from abrasive as well as adhesive wear. Knives made of this steel will not be distorted or bent irrespective of the material or solid you utilize it on.

Amazing Sharpness

Sharpening a knife made of S30V steel isn’t as simple as sharpening AUS 8 steel due to its hardness. When the steel is hard, you will find it hard to sharpen the knife. Obtaining a well-defined edge will take some energy and sweat as it has strong wear resistance. So, if you want to obtain a sharp edge with knives made from this material, you will require diamond tools to hone it.

On the other hand, pay for the difficulty in sharpening; it keeps its sharpness for many uses, so you’ll not need to go under the pressure of honing it from time to time.

Utmost Stiffness

For steel to provide superb stiffness, you may need to give up hardness. And the fact that S30V steel provides superb hardness and corrosion resistance, its stiffness isn’t the most excellent. 

Not to say that it’s terrible; however, there are stiff steels available than the S30V. On the other hand, it will take a lot of tough uses with knives made from this steel prior to starting to crack, chip, and break. 

Top Knives with S30V Steel 

Spyderco Paramilitary 2

S30V is the best kind of steel. It boasts amazing features of high quality knife steel with solid corrosion resistance, amazing edge retention, and toughness. 

We will begin the list with the star. The state-of-the-art Spyderco Paramilitary 2 is extensively termed as one of the most excellent all-around knives available and what makes it apart from the rest is the S30v material. At this point, the PM2 knives are also available in S110V.

Does Knife Made S30V steel Material Prone to Rust?

Knives made of S30V steel are not prone to rust as the material has 14 percent chromium that provides good corrosion resistance. On the other hand, this steel is also prone to corrosion if exposed to corrosion agents. So, if you buy a knife made of this material, make sure to clean it every after use. Doing so will keep it rust-free, and you can use it for a long time. 

Is S30V Reliable Knife Steel?

When you look at its properties and benefits, it is safe to say that it is reliable and ideal for knives. The superb wear resistance, hardness, decent toughness, and corrosion resistance make it a perfect option for manufacturers. 

To Sum Up

S30V steel is made to provide balanced stainless steel that can provide toughness, good grindability, edge retention, and corrosion resistance knives. So, if you’ve been searching for a confirmation to purchase a knife made with S30V steel, this article should provide you with good information.
