Both steels perform exceptionally well, but their priorities differ.
VG10 focuses on versatility and ease of maintenance, while M390 emphasizes maximum cutting performance.
Chemical Composition Comparison
Although exact compositions vary slightly depending on production tolerances and heat treatment, the major alloying elements remain consistent.
| Element | VG10 | M390 |
|---|---|---|
| Carbon | High | Very High |
| Chromium | High | Very High |
| Vanadium | Moderate | High |
| Molybdenum | Moderate | High |
| Tungsten | Small Amount | — |
| Cobalt | Present | — |
| Silicon | Present | Present |
| Manganese | Present | Present |
Rather than memorizing percentages, understanding the function of each alloying element provides greater insight into knife performance.
Carbon – The Foundation of Hardness
Carbon is the most important alloying element in knife steel.
Its primary roles include:
- Increasing hardness
- Improving edge retention
- Forming hard carbides
- Enhancing wear resistance
Both VG10 and M390 contain enough carbon to achieve high hardness suitable for premium knives.
However, M390 contains more carbon overall, allowing it to produce a greater volume of wear-resistant carbides.
This contributes to its exceptional edge retention.
Chromium – Stainless Performance
Chromium gives both steels their stainless properties.
It helps form a protective oxide layer that resists:
- Rust
- Food acids
- Moisture
- Humidity
- Staining
Both steels offer outstanding corrosion resistance.
However, M390 generally provides even greater protection because of its optimized alloy balance and carbide distribution.
Vanadium – Wear Resistance and Fine Grain Structure
Vanadium contributes to several critical properties.
These include:
- Grain refinement
- Edge stability
- Wear resistance
- Fine carbide formation
VG10 contains enough vanadium to improve cutting performance while maintaining relatively easy sharpening.
M390 contains substantially more vanadium, creating an extremely wear-resistant edge that stays sharp much longer.
Molybdenum – Strength and Durability
Molybdenum enhances:
- Wear resistance
- Strength
- Hardenability
- Corrosion resistance
Both steels benefit from molybdenum additions, although M390 contains significantly more.
This contributes to its outstanding durability during extended cutting.
Tungsten in VG10
One unique feature of VG10 is the addition of a small amount of tungsten.
Tungsten helps:
- Increase hardness
- Improve wear resistance
- Support edge stability
Although present in relatively modest amounts, it contributes to the balanced cutting performance for which VG10 is known.
Cobalt in VG10
VG10 also contains cobalt.
Cobalt helps the steel respond more effectively to heat treatment, allowing it to achieve higher hardness while maintaining good stability.
Rather than directly increasing edge retention, cobalt supports the development of the steel’s overall mechanical properties.
Powder Metallurgy vs Conventional Steel
Perhaps the biggest difference between these steels lies in how they are manufactured.
VG10 Manufacturing
VG10 is produced using a conventional steelmaking process.
Molten steel is cast into ingots before being forged, rolled, and heat treated.
This traditional method has been used successfully for decades and produces a reliable, durable knife steel.
M390 Manufacturing
M390 uses powder metallurgy.
Instead of casting large ingots, molten steel is atomized into microscopic powder particles.
These particles are then consolidated under high temperature and pressure.
The result is:
- Extremely fine carbide distribution
- Greater uniformity
- Improved wear resistance
- Better edge stability
- Enhanced overall performance
This advanced process explains why M390 consistently outperforms many conventional stainless steels in wear resistance and edge retention.
