Steel is one of the essential components for any blade, and which type you should use can make all the difference in quality.
The choice between AUS-8 and D2 is often tricky, as they each have advantages.
So, which one is better for high-quality knife making?
The answer is:
If you’re looking for cheaper knives that are water-resistant, then go with the AUS 8 steel, whereas if your goal is to have increased edge retention or greater ease when sharpening (or both), choosing D2 steel would be ideal. But D2 does not have as much corrosion resistance.
In this article, we will dive deep into the analysis between D2 vs AUS8 so that you can make an educated decision!
What is D2 Steel – What are its properties?
D2 steel is a high-carbon, high-chromium tool steel that is heat-treated to a hardness of 60-62 Rockwell C. As a result, it has excellent wear resistance and toughness. D2 steel is often used in applications with high wear resistance and toughness, such as cutting tools, dies, punches, and shear blades.
The total composition of D2 is:
- carbon- 1.55%
- chromium- 12.00%
- manganese- 0.60%
- silicon- 0.60%
- vanadium- 0.70%
- nickel- 0.30%
- molybdenum- 0.60%
Physical properties of D2 Steel:
- Thermal conductivity- 60 BTU/hr-ft-°F
- Specific heat capacity- 0.11 BTU/lb-°F
- Electrical resistivity- 474 ohm-cm
- Modulus of elasticity- 30 x 106 psi
What is AUS 8 Steel – is it suitable for Knifemaking?
AUS 8 steel is a high-carbon, high-chromium stainless steel that is heat-treated to a hardness of 58-60 Rockwell C. As a result, it has excellent corrosion resistance and toughness.
As a result, AUS 8 steel is often used in applications where corrosion, water resistance, and toughness are required, such as knives and scissors.
The total composition of AUS 8 Steel is:
- carbon- 0.75%
- chromium- 14.00%
- manganese- 0.50%
- silicon- 1.00%
- vanadium- 0.10%
- nickel- 0.50%
Physical properties of AUS 8 Steel:
- Density- 0.284 lbs/in3
- Thermal conductivity- 44 BTU/hr-ft-°F
- Specific heat capacity- 0.12 BTU/lb-°F
- Electrical resistivity- 474 ohm-cm
- Modulus of elasticity- 29 x 106 psi
D2 VS AUS 8 Steel which is better for knife making?
Regarding knife making, both D2 and AUS 8 steel are good choices. They both have high durability and toughness, making them ideal for cutting tools.
Although D2 steel has superior toughness, it does have a few drawbacks.
D2 steel is slightly more brittle than AUS 8 steel, which can break more easily. It is also a bit more difficult to sharpen than other steels.
AUS 8 steel also has some benefits. It is corrosion-resistant and will not rust as quickly as other steels. It is also easy to sharpen, making it a good choice for those not experienced in knife sharpening.
The main downside to AUS-8 steel is that it is not as tough as D2 steel. This means it can break faster, especially if subjected to much stress.
No matter your choice, you can’t go wrong with either D2 or AUS 8 steel.
D2 steel Pros:
- High wear resistance and toughness
- Ideal for cutting tools
D2 steel Cons:
- Brittle; can break more easily
- More difficult to sharpen than other steels
AUS 8 steel Pros:
- Corrosion-resistant
- Easy to sharpen
AUS 8 steel Cons:
- Not as tough as some other steel
- Can break more easily if stressed too much
So, what is the bottom line?
There is no simple answer to this question. Both sheets of steel have pros and cons, depending on what you are looking for in a knife.
For example, if you want a tough knife that can take a beating, then D2 steel is the way to go. On the other hand, if you want a knife that is easier to sharpen and maintain, then AUS 8 steel is the better choice. Ultimately, it comes down to personal preference.
Frequently asked questions about D2 VS AUS 8 Steel.
Is D2 better than VG10?
In a word: yes. D2 is a high-carbon, high-chromium steel that offers excellent wear resistance and edge retention.
It is also easy to sharpen, making it an excellent choice for heavy-duty knives. VG10, on the other hand, is slightly less sturdy steel, but it is still very tough and can take a sharp edge.
Why is D2 steel so popular?
D2 steel is a popular choice for knives because it is tough and durable steel. It is also easy to sharpen, making it an excellent choice for heavy-duty knives. D2 steel is a high-carbon, high-chromium steel that offers excellent edge retention.
Is D2 better than Damascus?
Damascus steel is very hardy and durable, but it is not as easy to sharpen as D2 steel.
However, Damascus steel offers a unique and beautiful pattern not found in any other type of steel. Ultimately, deciding which steel is better depends on the individual’s preferences.
Does AUS 8 steel hold an edge?
AUS 8 steel is challenging and durable steel that can hold an edge. However, it is not as hard as D2 steel, so it may not hold an edge as long.
AUS 8 steel is a good choice for knives that see moderate use. It is also easy to sharpen, making it an excellent choice for those not as experienced with sharpening knives.
Is AUS 8 better than 440C?
AUS 8 is tough and durable steel. However, it is not as hard as 440C, so it may not hold an edge as long. 440C is a good choice for knives that see heavy use.
It is also easy to sharpen, making it an excellent choice for those not as experienced with sharpening knives. 440C is more sturdy steel, but it is more difficult to sharpen. It is a good choice for knives that see heavy use.
Both AUS 8 and VG 10 are tough and durable steels. However, AUS 8 is not as hard as VG 10, so it may not hold an edge as long. On the other hand, VG 10 is more sturdy steel but more challenging to sharpen.
