Choosing between 8Cr13MoV and D2? You’re not alone. These two steels are everywhere in the knife world—one known for easy care and affordability, the other for better edge retention. If you want a quick, clear comparison to help you pick the right steel for your next knife, you’re in the right place.
What is 8Cr13MoV Steel?
8Cr13MoV is a Chinese-made stainless steel, similar in composition to Japanese AUS-8. It’s widely used in budget-friendly knives due to its excellent balance of cost, corrosion resistance, and ease of sharpening.
Key Features:
- True stainless steel (13% chromium)
- Good corrosion resistance
- Easy to sharpen
- Affordable price point
For sellers, this means you can offer a reliable, low-maintenance knife at a highly competitive price point. Top brands like Spyderco and Kershaw have built entire product lines on its dependable nature.
What is D2 Steel?
D2 is a high-carbon, high-chromium tool steel with a century-long legacy in industrial work and knife making. It’s famous for high hardness and exceptional wear resistance. Often called a “semi-stainless steel,” its 12% chromium content requires some care.
Key Features:
- High hardness and edge retention
- Moderate corrosion resistance (requires maintenance)
- Excellent wear resistance
- Higher price
For sellers, D2 is a keyword that signals quality and toughness to knowledgeable buyers, allowing you to command a higher price.

8Cr13MoV vs D2: Chemical Composition
The table below compares the chemical composition of 8Cr13MoV and D2, highlighting the differences that impact their performance. The content of key elements directly affects hardness, corrosion resistance, and toughness.
| Element | 8Cr13MoV | D2 | Function |
|---|---|---|---|
| Carbon (C) | 0.80% | 1.55% | Increases hardness and wear resistance |
| Chromium (Cr) | 13.00% | 12.00% | Enhances corrosion and wear resistance |
| Molybdenum (Mo) | 0.15% | 0.80% | Improves toughness and hardenability |
| Vanadium (V) | 0.10% | 0.90% | Boosts wear resistance and edge retention |
| Manganese (Mn) | 0.40% | 0.60% | Improves hardenability |
| Nickel (Ni) | 0.20% | 0.30% | Increases toughness |
Summary:
D2’s higher carbon and vanadium content means more hard carbides, resulting in better edge retention and hardness. 8Cr13MoV’s higher chromium and nickel content provide better corrosion resistance and toughness.
Performance Comparison
| Parameter | 8Cr13MoV | D2 Steel |
|---|---|---|
| Corrosion Resistance | Good (true stainless) | Moderate (semi-stainless) |
| Hardness Range | 56–60 HRC (avg. 58–59) | 55–62 HRC (avg. 60–62) |
| Toughness | Higher (6/10) | Lower (3.5/10) |
| Edge Retention | Moderate (3/10) | Excellent (5/10) |
| Ease of Sharpening | Easy | Difficult |
| Price/Value | Very affordable | Higher price, strong value |
| Recommended Uses | EDC, kitchen, outdoor | Heavy-duty, hunting, tactical |
Corrosion Resistance
- 8Cr13MoV: With 13% chromium, it’s a true stainless steel. It performs reliably in humid or saltwater environments without frequent maintenance, making it great for kitchen or outdoor settings.
- D2: At 12% chromium, it offers moderate resistance. It will rust if neglected, especially in moist environments. A blade coating can help prevent rust.
- Seller’s Takeaway: 8Cr13MoV minimizes customer complaints about rust. For D2, consider offering it with a stone-washed finish or a PVD/Cerakote coating as a value-added feature. This not only prevents rust but also enhances visual appeal.
Hardness
- 8Cr13MoV: Typically hardened to 58-59 HRC, offering a good balance of hardness and toughness.
- D2: Can be pushed to 60-62 HRC, resulting in superior wear resistance for demanding tasks.
- Seller’s Takeaway: The HRC rating is a powerful spec to list on your product page. D2’s higher HRC is a quantifiable metric that justifies a higher price to informed buyers.
Toughness
- 8Cr13MoV: More tough and less prone to chipping. According to Knife Steel Nerds, it scores a 6/10 for toughness. This makes it more forgiving when cutting hard materials.
- D2: More brittle due to its large carbide structure, scoring a 3.5/10. It can be prone to micro-chipping under hard use.
- Seller’s Takeaway: Frame this for your audience. For a rugged “survival” knife meant for batoning wood, 8Cr13MoV is a more forgiving choice. For a slicing-focused tactical or utility knife, D2’s risk of chipping is minimal.
Edge Retention
- 8Cr13MoV: Moderate edge retention, rated 3/10. It will need more frequent sharpening.
- D2: Excellent edge retention, rated 5/10. It holds a working edge much longer. However, the edge on a D2 knife can sometimes dull quickly due to micro-chipping, so real-world performance depends heavily on the heat treatment and blade geometry.
- Seller’s Takeaway: D2’s edge retention is its headline feature and a primary reason customers pay a premium. However, this is also where your brand’s reputation is on the line. Partnering with a manufacturer who masters the heat treatment process is non-negotiable.

Sharpenability
- 8Cr13MoV: Very easy to sharpen with basic equipment, making it ideal for beginners.
- D2: Difficult to sharpen due to its hard carbides, often requiring diamond or ceramic stones.
- Seller’s Takeaway: Position this as a benefit either way. For 8Cr13MoV: “Effortless to maintain a razor-sharp edge.” For D2: “It’s tough to sharpen because it’s tough, but you’ll have to do it far less often.”
Price
In the US market, 8Cr13MoV knives usually cost between $20 and $65, averaging around $40, making them affordable and easy to maintain. D2 knives range from $40 to $65, with an average near $50, offering better edge retention and wear resistance.
For sellers: 8Cr13MoV suits budget buyers and large inventory due to low maintenance needs, while D2 commands higher prices and targets enthusiasts willing to invest in blade care. This pricing gap allows clear product positioning to maximize sales.
