What is 9Cr18MoV steel? A Complete Review:

When looking for a brand new knife, the type of steel its blade is made of is crucial for deciding whether the knife will meet your needs or not. You might have already heard the narrative about good steel and bad steel. But when you think about it, all the steels are good in certain areas, and the good one for you is one that fits your standards.

Today, we'll focus on one of the steels that have been used in the knife industry for a long time—9Cr18MoV Steel. Our guide will focus on the steel composition, properties, and equivalent steel grades available. By the time you're done reading this guide, you'll have decided whether this is a good steel for you or not.

What is 9Cr18MoV steel?

The 9Cr18MoV is a Chinese made stainless steel with high Chromium and carbon content for great hardness and unparalleled corrosion resistance. It's mainly used to make corrosion vulnerable cutting tools like stainless steel knives, surgical blades, etc.

The steel gives you good value for money for the good balance it strikes between quality and pricing.

9Cr18MoV composition

The stainless steel features high amounts of Chromium Carbon and Molybdenum in that order—giving it extreme hardness and corrosion resistance. The 9Cr18MoV steel composition also includes a variety of other elements, as shown in this table.

The 9Cr18MoV shows Chromium as the most abundant element in the steel composition. It qualifies the 9Cr18MoV as stainless steel. But most importantly, it enables the steel to exhibit greater tensile strength and edge retention ability. Additional benefits of having Chromium in the steel include enhanced corrosion and wear resistance.

The high amounts of carbon increase this steel's overall hardness and its ability to resist wear and corrosion.

Nitrogen and phosphorous help increase the steel strength. Nitrogen goes a step further to improve its edge retention.

Silicon improves the 9Cr18MoV strength.

Molybdenum appears in high amounts in this steel to ensure high machinability and increased strength. And the 0.03% Sulfur further increases the machinability of this steel.

Vanadium has a composition of 0.12%, which is great for boosting the 9Cr18MoV hardenability and improving its resistance to wear.

9cr18MoV Steel Properties

Having studied this Chinese stainless steel composition, it's now easier to bring out the key properties it will offer you when used to make a knife blade.

9cr18MoV Steel Properties

Hardness

The 9cr18MoV hardness stands at 58-60 HRC according to the Rockwell Hardness Chart. Without a single doubt, this is a great amount of hardness and is precisely what you find in high-quality knives from popular brands like Spyderco, Buck, Cold Steel, and others,

The high carbon content in the composition of this steel is responsible for the high hardness. The presence of Vanadium in the composition boosts the steel vanadium carbide content, improving its overall hardness and wear resistance.

Edge retention

This high hardness degree gives the stainless steel a handful of amazing benefits, including the ability to hold an edge for pretty long.

The high levels of Carbon (close to 1%) give the steel a solid build and the ability to withstand friction. In conjunction with high hardness (rated 60HRC), it constitutes the perfect recipe for keeping a good cutting edge for a long period of time.

Don't forget that Vanadium plays a role in creating vanadium carbide. This extremely hard substance further enhances the steel edge retention ability.

Toughness

The rule of thumb is that the harder a steel is, the more brittle it becomes. And the more brittle it becomes, the less tough it is. With that said, you don't expect this steel to be the toughest guy around.

However, the manufacturer has included key elements like Nickel and Manganese in its compensation to increases its tensile strength. This enables a 9CR18MoV steel knife to deliver decent toughness.

Corrosion resistance

Firstly, this is stainless steel, which tells you something about it: it's good for corrosion resistance.

9Cr18MoV steel knives

The steel boasts a high amount of Chromium (at 18%), which is more than what's needed to make a steel stainless. Needless to say, this propels the steel corrosion resistance to a whole new level.

What's more, the steel features additional elements like Nickel and Molybdenum, which help fight against corrosion.

Sharpenability

So, we've just mentioned that this is hard steel. While this is good for knife longevity and ability to keep its edge, it does come with a sacrifice, which is sharpening difficulty. Yes, hard steel knives are pretty hard to sharpen, especially for beginners with little or no sharpening experience.

But then again, the 9CR18MoV knives have great edge retention and don't dull easily. It will take long before you can think about re-sharpening. The advanced sharpening systems on the market today will help you give the knife a razor-sharp edge and maintain it at that.

9CR18MoV vs other steels in its class

9cr18mov vs 440c

440c is the most similar grade of steel to the 9cr18mov. They share a very close chemical composition to that of 9cr18mov. Both have great edge retention and corrosion resistance properties and feature the same price range, giving you value for money.

Is 9Cr18MoV steel good for knives?

From the above discussion, we can agree that 9Cr18MoV is a great steel for knives. It boasts high hardness, good edge retention, and extreme corrosion resistance. It also delivers a decent amount of toughness. These characteristics make it good steel for EDC or kitchen knife.

Is 9Cr18MoV steel good for knives

However, the high hardness compromises the steel toughness and might not make a good knife used for camping, hiking, hunting, etc. This is because the less tough blade will not hold up to tough tasks associated with these outdoor tasks.

With such great features, this steel is slowly building a following of the world of knife users. In the next section, we'll review some of the best-rated knives made with this steel.
