Aus 8 Steel Review

Read on and we’ll explain why so many people choose knives made from AUS-8 Steel. The unique properties of this steel, in addition to its tensile strength, are why it is so popular.

Therefore, you may shop with full confidence for items made from this steel, most notably the knife.

Is AUS-8 considered a GOOD steel for knives?

Because of its optimal balance of sharpening potential and resistance to corrosion, AUS-8 steel may be found in a wide variety of knives of high quality. This is the primary reason for its widespread usage. Because of this, it is an excellent option for first-time knife purchasers who are interested in learning how to sharpen their own blades, as well as for employees in occupations that need an economical knife of high quality.

What Is AUS-8 Steel?

The Aichi Steel Corporation in Japan produces a variety of specialty steels, including AUS-8 steel, often known as 8A steel. In comparison to standard steels like 440C, D2, or CM-54, its quality is far higher.

In the modern steel industry, success hinges on being able to adjust the percentage of chromium and carbon added during the melting process. In order to create stainless steel, for instance, chromium is often added while carbon is decreased. The finished result, however, will certainly be harder to sharpen and will lose some of its previous sharpening potential.

Because of its unique composition, this steel is used in a variety of applications. It is toughened by heat treatment to the proper degree, often between 58 and 59 HRC (Hot-rolled coil). Thus, 8A steel offers endurance, stainless, enhanced sharpness, and abrasion resistance while having low carbon and chromium constituents.


aus 8 steel


It is very sharp and can slice through anything. It doesn’t need to be sharpened as often because of how long its edge holds. Use frequency is still a factor, however.


It has a high chromium to nickel ratio, which boosts its hardness and mechanical strength.

Edge retention

The optimal carbon content gives this steel its impressive toughness. Therefore, the knife edges are not easily chipped by tough substances.

Corrosion resistance

The likelihood of corrosion in steel exposed to chemicals is reduced because to its stainless characteristics and enough chromium. But it doesn’t imply the knife won’t corrode over time. Use it often in damp environments, and corrosion is still a possibility.

Abrasion resistance

Carbon and molybdenum are the main components of 8A steel. These two materials work well together to provide your knives excellent resistance to wear and tear.


Because it contains both molybdenum and sulfur, it can be easily machined into many shapes. It would be overstating the case to suggest that all of this steel’s qualities are superior. The fundamental properties of this steel, however, are assured and kept constant. AUS-8 steel contains everything you might want in a tool, including an excellent edge and a high degree of toughness.

Steels Other Than AUS-8

This article provides a quick overview of AUS-8 steel and how it compares to some other common steels. You will see why this steel is considered “Mid-Range Steel,” and you will get a good look at it to boot.

AUS-8 vs. VG-10

These two varieties of steel are comparable to one another because they both have high resistance to corrosion. Edge retention and durability are what set them apart. Superior edge retention may be seen in VG 10 steel, as compared to A8. Its strength, however, falls short of that of A8. When compared to AUS-8 steel, VG 10 is more difficult to manufacture.

AUS-8 against S30V

S30V has superior hardness and abrasion resistance over A8 steel. As a result, S30V knives are often longer than AUS-8 blades. However, because S30V is harder to machine than A8, making an S30v knife is a laborious process.

Compare and contrast AUS-8 with 8Cr13MoV

These two types of steel have distinct producers. AUS-8 is a Japanese knife set, whereas 8Cr13MoV originates in China. In spite of their similarities in production, AUS-8 is superior in terms of edge retention and corrosion resistance. Both are really sturdy, so that’s a commonality.

AUS-8 vs. D2

These two steel kinds are comparable in edge retention and corrosion resistance. When compared to AUS-8 in terms of hardness, though, D2 is clearly superior.


What steel is superior AUS 8 or D2?

A. D2 steel is of a higher grade than AUS-8 steel; it is tougher and has greater edge retention than AUS-8 steel, but D2 steel is not as resistant to corrosion as AUS-8 steel. The inverse of this is AUS-8. Therefore, you should go for AUS-8 if you want a knife that is inexpensive and more resistant to water. Choose D2 if you are looking for a high-end knife with less resistance to water.

What is the key difference between the AUS 8 and the AUS 8a version?

AUS-8 Steel is equivalent to 440 steel. Vanadium is used in the alloy to increase the steel’s overall hardness. When compared to high-carbon steel, AUS-8a steel is much easier to sharpen to a razor’s edge; nevertheless, it also loses its edge far more rapidly. The simple act of being exposed to air, according to a number of reviews found online, would render it uninteresting.

Does AUS-8 steel retain an edge?

In the realm of stainless steel, the AUS 8 grade presents an excellent trade-off between price and quality in the year 2023. It is able to withstand a very sharp edge.

What about AUS-8 stainless steel? Is it good for knives.

That’s correct. It’s a good steel for a knife in the middle price range. Features like stainless steel construction, high strength, fine edge retention, resistance to wear, etc. are all possible in a functional knife.

It is one of the best materials for making knives since it can be easily machined. With the right combination of hardness and toughness, it can be easily machined for shaping, reducing the potential for damage during the tooling process.

Because of this, the above question must be answered affirmatively. Thus, many producers consider it an ideal medium-priced knife material.

What’s the difference between AUS-8 and 440C?

In terms of durability and toughness, AUS-8 and 440C steel are often on par with one another. The ability to be manufactured is the only distinction. When compared to the 440C, the AUS-8 requires less effort to sharpen.


Maybe you’re certain that this steel is the best option for your knife. On the basis of the above, I recommend trying out an 8A knife, as you will never be let down by it.

The above AUS-8 Steel review may be helpful in comparing items and making judgments since it provides information about the wonderful steel qualities and their influence on the knives.
