What Is M390 Steel?
M390 is a premium stainless powder metallurgy steel developed specifically for applications requiring exceptional wear resistance, corrosion resistance, and long edge life.
Its combination of high carbon content and large amounts of chromium, vanadium, and molybdenum allows it to produce an extremely hard matrix filled with fine carbides.
These carbides are responsible for the steel’s impressive cutting longevity.
Unlike many traditional stainless steels, powder metallurgy allows these carbides to remain extremely fine and evenly distributed throughout the blade.
This manufacturing process improves:
- Edge stability
- Uniform hardness
- Corrosion resistance
- Wear resistance
- Overall consistency
Because of these characteristics, M390 has become one of the most respected premium stainless steels for high-end knives.
Typical hardness ranges from 60β62 HRC, although some makers heat treat it slightly higher.

Understanding Powder Metallurgy
Both steels are produced using powder metallurgy, a manufacturing method that differs significantly from conventional steel production.
Instead of pouring molten steel directly into ingots, the molten alloy is atomized into microscopic powder particles.
These powders are:
- Uniform in chemistry
- Extremely fine
- Nearly identical in size
The powder is then compressed under enormous pressure before being sintered into solid steel.
The result is:
- Smaller carbides
- Better carbide distribution
- Improved toughness
- Better machinability
- More consistent heat treatment
Without powder metallurgy, steels containing very high levels of chromium and vanadium would develop massive carbides that reduce toughness and make sharpening much more difficult.
This advanced process is one reason both steels command premium prices.
Chemical Composition Comparison
Although both steels are stainless and made through powder metallurgy, their alloy recipes differ enough to influence performance.
| Element | M390 | S35VN |
|---|---|---|
| Carbon | High | High |
| Chromium | Very High | High |
| Vanadium | High | Moderate |
| Molybdenum | Moderate | Moderate |
| Niobium | None | Present |
| Stainless | Yes | Yes |
The exact percentages matter less than understanding what each element contributes.
Carbon
Carbon is one of the most important ingredients in knife steel.
It enables:
- Higher hardness
- Better edge retention
- Greater wear resistance
Both steels contain enough carbon to achieve premium hardness levels suitable for demanding cutting applications.
Chromium
Chromium provides corrosion resistance while also contributing to carbide formation.
Both steels comfortably exceed the minimum chromium required to qualify as stainless steel.
M390 contains slightly more chromium, giving it a small advantage in corrosion resistance under harsh conditions.
Vanadium
Vanadium creates extremely hard carbides that significantly improve wear resistance.
These carbides help blades maintain sharpness over extended cutting sessions.
M390 contains noticeably more vanadium than S35VN.
This contributes to:
- Longer edge life
- Higher abrasion resistance
- Better slicing longevity
The trade-off is increased sharpening difficulty.
Molybdenum
Molybdenum improves:
- Corrosion resistance
- High-temperature stability
- Overall strength
Both steels use molybdenum to enhance stainless performance while supporting hardness during heat treatment.
Niobium
One major difference between these steels is the presence of niobium.
S35VN includes niobium carbides.
These carbides are smaller than many vanadium carbides and help improve:
- Toughness
- Edge stability
- Resistance to micro-chipping
This is one reason many users consider S35VN a better all-around steel for heavy everyday use.
Carbide Structure
Carbides determine much of a knife’s cutting performance.
Think of carbides as microscopic hard particles embedded throughout the steel.
These particles resist abrasion while supporting the cutting edge.
M390 contains:
- More total carbides
- Harder carbides
- Higher wear resistance
S35VN contains:
- Slightly fewer carbides
- Better carbide balance
- Greater toughness
This distinction becomes important when comparing edge retention and durability, which we’ll cover in the next section.
Initial Performance Summary
Even before discussing cutting performance, the differences become clear.
M390 Prioritizes

Hardness, Edge Retention, Toughness & Corrosion Resistance
In Part 1, we explored the composition and manufacturing process behind M390 and S35VN. While their alloy chemistry explains why these steels perform differently, real-world users are usually more interested in practical questions:
- Which steel stays sharp longer?
- Which is less likely to chip?
- Which performs better outdoors?
- Which is easier to maintain?
- Which offers the best balance of performance?
Let’s examine each category in detail.
Hardness Comparison
Hardness is commonly measured using the Rockwell C (HRC) scale. A harder blade generally resists wear better and can support a finer cutting edge, but excessive hardness may reduce toughness.
Typical Hardness
| Steel | Typical Hardness |
|---|---|
| M390 | 60β62 HRC |
| S35VN | 59β61 HRC |
Although the numerical difference seems small, even one Rockwell point can noticeably affect edge retention and sharpening.
M390
M390 is often heat treated near the upper end of its hardness range, allowing it to maintain an extremely fine cutting edge for long periods.
Benefits include:
- Better slicing performance
- Reduced edge rolling

Edge Retention
Edge retention refers to how long a knife remains sharp during normal cutting.
This is one of the biggest reasons people choose premium steels.
Several factors affect edge retention:
- Hardness
- Carbide volume
- Carbide type
- Heat treatment
- Edge geometry
Among these, carbide volume is particularly important.
Why M390 Excels
M390 contains a higher amount of extremely hard chromium and vanadium carbides.
