Composition and Hardness
In order to understand the performance and characteristics of S35VN and M390 steels, it is important to delve into their composition and hardness. The steel composition determines various properties, while hardness plays a significant role in edge retention and wear resistance.
S35VN steel is known for its exceptional composition, consisting of 1.4% carbon, 14% chromium, 3% vanadium, 2% molybdenum, and other elements such as 0.5% niobium. The addition of niobium contributes to the steel’s strength and toughness, enhancing its overall performance. This composition results in a steel that is highly resistant to wear and chipping, making it ideal for demanding applications.
On the other hand, M390 steel boasts a composition that includes 1.9% carbon, 20% chromium, 1% molybdenum, 4% vanadium, and small amounts of other elements. The higher percentage of chromium in M390 contributes to its excellent corrosion resistance. Additionally, the presence of vanadium and molybdenum further enhances M390’s wear resistance and toughness.
Now, let’s discuss the hardness of these steels. S35VN typically has a hardness ranging from 59-61 HRC (Rockwell Hardness Scale), which provides excellent edge retention and resistance to deformation under pressure. M390, on the other hand, exhibits a slightly higher hardness, ranging from 60-62 HRC. This increased hardness contributes to M390’s ability to maintain a sharp edge for prolonged periods of time.
The composition and hardness of both S35VN and M390 steel play crucial roles in determining their performance and suitability for various applications. In the next sections, we will explore other important aspects such as toughness, corrosion resistance, edge retention, and sharpening ease to further understand the differences between these two exceptional steels.
Toughness and Corrosion Resistance
When it comes to selecting the right steel for your knife, two essential factors to consider are toughness and corrosion resistance. In this section, we will dive deep into the properties of S35VN and M390 to determine how they perform in these areas.
Toughness
Toughness refers to a steel’s ability to withstand heavy usage without chipping, cracking, or breaking. It is a critical characteristic for knives that undergo rigorous tasks and high-impact applications.
S35VN, developed by Crucible Industries, is known for its exceptional toughness. With a fine-grained structure and added niobium, it offers excellent resistance to chips and fractures, making it highly durable in demanding conditions.
M390, on the other hand, is a powder metallurgy stainless steel manufactured by Bohler-Uddeholm. It boasts outstanding toughness due to its high vanadium and chromium content. This steel can endure heavy use and offers excellent resistance to chipping and breaking.
Both S35VN and M390 exhibit exceptional toughness, providing users with confidence in the durability and reliability of their knives during challenging tasks.
Corrosion Resistance
Corrosion resistance is crucial for knives, especially when exposed to moisture, humidity, or corrosive elements. A highly corrosion-resistant steel ensures the longevity and performance of a knife in various environments.
S35VN offers good corrosion resistance with its balanced composition of chromium and vanadium. This steel forms a passive layer on its surface, protecting it from oxidation and corrosion.
M390, with its high chromium content, provides excellent corrosion resistance. It also contains high amounts of vanadium and molybdenum, which further enhance its ability to resist corrosion in wet or humid conditions.
Overall, both S35VN and M390 exhibit commendable levels of corrosion resistance, ensuring that your knives can stand up to the elements and maintain their performance over time.
In the next section, we will evaluate the edge retention and sharpening ease of S35VN and M390, helping you choose the optimal steel for your specific needs.
Edge Retention and Sharpening Ease
When it comes to choosing a high-performance knife steel, two popular options often come up for comparison: S35VN and M390. In this section, we will delve into the crucial aspects of edge retention and sharpening ease to determine which steel stands out in these areas.
Edge Retention
The ability of a knife to retain its sharpness over time, also known as edge retention, is a critical factor for many knife enthusiasts. S35VN and M390 are both known for their exceptional edge retention capabilities, but they differ slightly in their performance.
S35VN, developed by Crucible Industries, offers an impressive balance between hardness and toughness, resulting in excellent edge retention. With a high volume of vanadium and niobium carbides, S35VN forms a robust and wear-resistant edge that can withstand prolonged use without frequent re-sharpening.
On the other hand, M390, a stainless steel from Bohler-Uddeholm, boasts even better edge retention compared to S35VN. Its high carbon content and a blend of other elements such as chromium and vanadium contribute to its exceptional hardness and wear resistance, making it an excellent choice for those who prioritize edge retention.
Sharpening Ease
While edge retention is crucial, the ease of sharpening the steel is also an essential consideration for knife users. After all, even the best edge retention steel will eventually require sharpening.
When it comes to sharpening ease, S35VN holds the advantage. This steel can be sharpened with relative ease, thanks to its balanced composition and good grindability. It allows for efficient and precise re-sharpening, making it accessible even for those who are new to knife maintenance.
M390, on the other hand, can be slightly more challenging to sharpen due to its exceptional hardness. While it can still be sharpened effectively with appropriate tools and techniques, it may require some experience or professional assistance to achieve the best results.
In conclusion, both S35VN and M390 offer incredible edge retention, but M390 surpasses S35VN in this aspect. However, S35VN takes the lead in terms of sharpening ease, making it a more user-friendly choice. Consider your priorities and skill level when deciding which steel is the better fit for your needs.
Conclusion
After carefully analyzing the properties and performance of S35VN and M390, it is clear that both steels offer exceptional qualities for knife making. However, when it comes to the ultimate verdict in the S35VN vs M390 steel comparison, one steel stands out as the superior choice.
Both S35VN and M390 demonstrate remarkable durability, excellent edge retention, and strong corrosion resistance. However, M390 surpasses S35VN in terms of its overall performance and versatility. With its higher carbon content and additional elements like vanadium and tungsten, M390 exhibits an impressive combination of hardness, toughness, and wear resistance.
Another aspect where M390 excels is sharpening ease. While both steels can be sharpened to a razor-sharp edge, M390 tends to retain its sharpness for a longer duration, reducing the need for frequent sharpening. This makes it an ideal choice for those seeking a low-maintenance, high-performance knife.
In conclusion, based on the comprehensive comparison of S35VN vs M390, the final verdict tilts in favor of M390. Its superior performance, including exceptional durability, outstanding edge retention, corrosion resistance, and ease of sharpening, make it the top choice for knife enthusiasts and professionals alike.
