VG10 vs AUS-8 Steel Chemical Composition Comparison
Although both steels are stainless, their alloy compositions reveal why they perform differently.
| Element | VG10 | AUS-8 | Purpose |
|---|---|---|---|
| Carbon | ~1.0% | ~0.75% | Hardness and edge retention |
| Chromium | ~15% | ~14% | Corrosion resistance |
| Molybdenum | ~1.0% | ~0.3% | Strength and corrosion resistance |
| Vanadium | ~0.25% | ~0.25% | Grain refinement and wear resistance |
| Cobalt | ~1.5% | — | Improves hardness during heat treatment |
| Nickel | — | ~0.5% | Toughness and corrosion resistance |
| Manganese | ~0.5% | ~0.5% | Hardenability |
| Silicon | ~0.6% | ~1.0% | Strength and manufacturing |
At first glance, the compositions appear similar, but several important differences significantly affect real-world performance.
Why Higher Carbon Matters
One of the biggest distinctions is carbon content.
VG10 contains approximately 1.0% carbon, while AUS-8 typically contains around 0.75%.
Higher carbon enables:
- Higher hardness
- Better edge retention
- Improved wear resistance
- Finer cutting edges
However, increasing carbon also makes steel less forgiving if heat treatment is not properly controlled.
This is one reason premium manufacturers invest significant effort into optimizing VG10 heat treatment.
The Importance of Chromium
Both steels contain enough chromium to qualify as stainless steels.
VG10’s approximately 15% chromium provides excellent protection against:
- Kitchen acids
- Fruit juices
- Humidity
- Food preparation
- Everyday washing
AUS-8 contains about 14% chromium, which is also excellent.
For normal users, both steels resist rust extremely well when cleaned and dried after use.
In practical terms, corrosion resistance is one area where both steels perform exceptionally well.
Why Cobalt Gives VG10 an Advantage
One of VG10’s defining characteristics is its cobalt content.
Cobalt helps steel achieve:
- Higher hardness
- Better temper stability
- More consistent heat treatment
- Improved edge stability
This allows many manufacturers to harden VG10 into the 60–62 HRC range while maintaining excellent cutting performance.
AUS-8 does not contain cobalt, limiting its achievable hardness without sacrificing toughness.
Vanadium and Carbide Formation
Both steels contain vanadium, but its role differs depending on the overall alloy.
Vanadium forms extremely hard carbides that improve:
- Wear resistance
- Edge stability
- Grain refinement
- Sharpening consistency
In VG10, vanadium works alongside higher carbon and cobalt to create a harder, longer-lasting cutting edge.
In AUS-8, vanadium still improves grain structure but contributes less to overall wear resistance because of the steel’s lower hardness and carbon content.
Microstructure Differences
Perhaps the most important difference between these steels lies in their microstructure.
A properly heat-treated VG10 blade develops a fine martensitic structure with evenly distributed chromium and vanadium carbides. This fine carbide distribution allows the blade to achieve excellent sharpness while maintaining good wear resistance and corrosion protection.
AUS-8 also develops a fine-grained martensitic structure, but with fewer hard carbides due to its lower carbon and alloy content. As a result, it sacrifices some edge retention in exchange for increased toughness and easier sharpening.
This difference in carbide volume explains why VG10 typically stays sharp longer, while AUS-8 is quicker to restore once it becomes dull.
VG10 vs AUS-8 Steel Hardness Comparison
Hardness is one of the most influential characteristics of any knife steel because it directly affects edge retention, cutting performance, and durability. It is commonly measured using the Rockwell Hardness Scale (HRC).
Although VG10 and AUS-8 are both Japanese stainless steels, they are typically heat-treated to different hardness levels, giving each steel its own strengths.
| Steel | Typical Hardness |
|---|---|
| VG10 | 60–62 HRC |
| AUS-8 | 57–59 HRC |
At first glance, a difference of two or three HRC points may seem minor. In reality, it has a significant impact on how the knife performs.
VG10’s higher hardness allows it to maintain a finer edge for much longer before dulling. This is especially valuable in precision cutting tasks where consistent sharpness is essential.
AUS-8, with its slightly lower hardness, sacrifices some edge retention in exchange for greater toughness and resilience. Rather than chipping under stress, the edge is more likely to roll slightly, which is generally easier to correct with sharpening.
Why Heat Treatment Matters More Than Steel Alone
Steel composition is only part of the equation. Heat treatment has an enormous influence on final performance.
A premium VG10 knife from a reputable Japanese maker often outperforms a poorly heat-treated VG10 blade by a wide margin. Likewise, a well-treated AUS-8 knife can outperform many cheaper stainless steels despite its modest alloy composition.
Manufacturers adjust heat treatment based on the intended use:
- Kitchen knives: Higher hardness for better slicing.
- Outdoor knives: Slightly lower hardness for increased toughness.
- Folding knives: Balanced hardness for everyday use.
For this reason, always consider the manufacturer’s reputation in addition to the steel type.

Edge Retention
One of the most common questions buyers ask is:
Which steel stays sharp longer?
In this category, VG10 is the clear winner.
The combination of higher carbon content, increased hardness, cobalt, molybdenum, and vanadium allows VG10 to resist wear far better than AUS-8.
Typical Edge Retention
| Steel | Edge Retention |
|---|---|
| VG10 | Excellent |
| AUS-8 | Good |
Why VG10 Holds an Edge Longer
VG10 benefits from:
- Higher carbon content
- Higher hardness
- More wear-resistant carbides
- Better edge stability
- Improved resistance to abrasive wear
As a result, VG10 can continue making clean cuts long after AUS-8 begins to lose its shaving sharpness.
Professional chefs appreciate this because they can prepare large amounts of food before needing to hone or sharpen the knife.
AUS-8 in Daily Use
AUS-8 dulls faster, but not dramatically faster for average users.
For people who:
- Cook a few meals per week
- Carry an everyday pocket knife
- Go camping occasionally
the difference may not be immediately noticeable.
Many users actually prefer sharpening a knife more often if sharpening is quick and simple.
Wear Resistance
Wear resistance measures how well steel resists gradual abrasion during cutting.
This characteristic becomes important when repeatedly cutting abrasive materials such as:
- Cardboard
- Rope
- Dense vegetables
- Fibrous meat
- Hard cheeses
- Plastic packaging
Wear Resistance Comparison
| Steel | Wear Resistance |
|---|---|
| VG10 | High |
| AUS-8 | Moderate |
VG10’s harder carbides significantly slow edge wear.
This makes it ideal for users who expect long intervals between sharpening sessions.
AUS-8 experiences faster edge wear but compensates with easier maintenance.
Toughness
Toughness refers to a blade’s ability to absorb impacts and resist chipping or breaking.
Contrary to popular belief, the hardest steel is not always the strongest.
Higher hardness often reduces toughness.
Toughness Comparison
| Steel | Toughness |
|---|---|
| VG10 | Good |
| AUS-8 | Very Good |
AUS-8 performs exceptionally well in this category.
Its lower hardness allows the blade to flex slightly under stress rather than chip.
This makes AUS-8 particularly suitable for:
- Hunting knives
- Survival knives
- Camp knives
- Utility knives
- Everyday carry folders
VG10 is still reasonably tough, but it is designed primarily as a high-performance cutting steel rather than a heavy-duty impact steel.
Edge Stability
Edge stability describes how well a very thin edge survives real-world use.
VG10 performs remarkably well thanks to:
- Fine grain structure
- Stable carbides
- Excellent heat treatment response
This allows manufacturers to grind the blade extremely thin without sacrificing cutting performance.
Japanese chef knives made from VG10 often feature exceptionally thin geometries that glide effortlessly through food.
AUS-8 also takes a fine edge, but manufacturers usually grind it slightly thicker because it is intended for more versatile applications.
Corrosion Resistance
Both steels are considered excellent stainless steels.
For normal kitchen use, either steel offers more than enough rust resistance when properly maintained.
Corrosion Resistance Comparison
| Steel | Corrosion Resistance |
|---|---|
| VG10 | Excellent |
| AUS-8 | Excellent |
Both steels resist:
- Moisture
- Kitchen acids
- Fruit juices
- Vegetables
- Humidity
VG10’s slightly higher chromium and molybdenum content provides a small advantage, especially in demanding environments.
However, in everyday use, most owners will notice very little practical difference.
VG10 vs AUS-8 Steel Food Acids and Kitchen Performance
Kitchen knives encounter many acidic ingredients:
- Tomatoes
- Citrus fruits
- Onions
- Vinegar
- Apples
- Wine-based sauces
Fortunately, both VG10 and AUS-8 handle these environments extremely well.
Neither steel requires the constant drying and oiling associated with high-carbon non-stainless steels.
For home cooks, maintenance is straightforward:
- Wash after use
- Dry thoroughly
- Avoid prolonged soaking
- Store in a dry location
Following these simple steps will keep either steel in excellent condition for many years.
