N690 Steel Review
An Independent Guide
When knife enthusiasts discuss premium stainless steels, names such as VG10, 14C28N, MagnaCut, SG2, and M390 often dominate the conversation. However, one steel has quietly earned a reputation as one of the most balanced and practical knife steels available today: N690.
For decades, N690 has been a favorite among custom knife makers, European manufacturers, outdoor enthusiasts, and kitchen knife craftsmen. It offers a combination of corrosion resistance, toughness, edge retention, and ease of maintenance that makes it attractive for both professional and everyday users.
Unlike some modern “super steels” that focus heavily on extreme wear resistance, N690 aims for balance. As a result, many knife makers consider it one of the best all-around stainless steels for real-world use.
But how good is N690?
Can it compete with modern powder metallurgy steels?
Is it suitable for kitchen knives?
And why do so many custom knife makers continue to use it despite the arrival of newer steels?
In this complete guide, we’ll explore everything you need to know about N690 steel.
What Is N690 Steel?
N690 is a premium stainless steel produced by the Austrian steel manufacturer.
It was originally developed for applications requiring:
- Corrosion resistance
- Wear resistance
- Toughness
- Reliable performance
Over time, knife makers discovered that N690 possessed characteristics that made it exceptionally well-suited for blade production.
Today, N690 is commonly used for:
- Chef knives
- Kitchen knives
- Hunting knives
- Outdoor knives
- EDC knives
- Tactical knives
- Handmade custom knives
Its versatility is one of the reasons for its enduring popularity.
N690 Steel Composition
Typical composition:
| Element | Percentage |
|---|---|
| Carbon | 1.07% |
| Chromium | 17.3% |
| Cobalt | 1.5% |
| Molybdenum | 1.1% |
| Vanadium | 0.1% |
| Manganese | 0.4% |
| Silicon | 0.4% |
This alloy composition provides a highly balanced combination of properties.
The relatively high chromium content contributes to excellent corrosion resistance, while carbon and molybdenum improve hardness and wear resistance.
One particularly interesting feature is the addition of cobalt.
The cobalt helps improve heat treatment response and contributes to overall performance.
Is N690 Stainless Steel?
Yes.
N690 is considered a true stainless steel.
With over 17% chromium, it offers excellent protection against:
- Rust
- Staining
- Kitchen acids
- Humidity
- Food moisture
For kitchen knife users, this means significantly less maintenance compared with carbon steels such as:
- 1095
- 52100
- White Steel #2
- Blue Steel #2
Most users only need basic cleaning and drying after use.

Why Knife Makers Love N690
Many custom makers appreciate N690 because it provides a rare balance between performance and practicality.
Advantages include:
- Excellent corrosion resistance
- Good edge retention
- Reliable toughness
- Easy maintenance
- Attractive finish quality
For handmade knives, these characteristics are particularly valuable because they appeal to a wide range of customers.
Hardness of N690
Most N690 knives operate between:
58–61 HRC
Typical hardness ranges:
| Knife Type | HRC |
| Kitchen Knife | 59–61 |
| Hunting Knife | 58–60 |
| EDC Knife | 59–61 |
| Outdoor Knife | 58–60 |
A properly heat-treated N690 kitchen knife is often found around 60 HRC.
This provides an excellent balance between:
- Edge retention
- Toughness
- Sharpen ability

Edge Retention
Edge retention is one of N690’s strongest attributes.
While it may not compete with extreme wear-resistant steels such as:
- M390
- S90V
- S110V
it still offers very respectable edge life.
For most kitchen users, the difference is often less noticeable than expected.
Benefits include:
- Long-lasting working edge
- Reliable performance
- Good wear resistance
Many users find N690 stays sharp long enough while remaining much easier to sharpen than many super steels.

Toughness
Toughness is an area where N690 performs well.
Advantages include:
- Reduced chipping risk
- Better durability
- Reliable edge stability
This makes N690 suitable for a wide variety of knife designs.
Kitchen knives especially benefit because they often encounter lateral stresses during food preparation.
Sharpening Performance
Many knife owners underestimate the importance of sharpening ease.
A steel that takes twice as long to sharpen may not be practical for every user.
N690 offers:
- Relatively easy sharpening
- Predictable burr formation
- Good polishing response
- Excellent edge refinement
Compared with high-carbide powder steels, sharpening N690 is significantly easier.
This is one reason professional sharpeners often appreciate it.
Corrosion Resistance
This is arguably N690’s greatest strength.
Its high chromium content provides outstanding corrosion resistance.
Benefits include:
- Excellent rust resistance
- Resistance to kitchen acids
- Low maintenance requirements
For cooks working with:
- Tomatoes
- Citrus fruits
- Onions
- Vinegar
N690 performs exceptionally well.
Many users never experience corrosion issues at all.

For kitchen knives, the performance gap is often smaller than expected.
N690 vs 440C
Before modern powder steels became popular, 440C was one of the most respected stainless knife steels.
440C Advantages
- Proven history
- Easy availability
N690 Advantages
- Better corrosion resistance
- Better heat treatment response
- Improved edge retention
- Better overall balance
Many knife makers consider N690 a modern evolution of the classic 440C concept.
Heat Treatment: The Secret Behind Great N690 Knives
Many buyers focus entirely on steel type.
Experienced knife makers know that heat treatment often matters even more.
Proper heat treatment determines:
- Final hardness
- Toughness
- Edge stability
- Wear resistance
A well-treated N690 knife can outperform a poorly treated premium steel.
This is why reputable custom makers invest significant time into heat treatment protocols.
