If you’re searching for the best knife or doing some research, you will see the many numbers of different knife materials available out there. There is more than 3000 steel grade out there with regards to steel. Also, you will find that one popular kind of steel is the N690. A lot of knifemakers opt for this kind of steel as it makes a dependable blade that is very corrosion resistant.
While this steel has a lot of benefits, this also comes with some flaws. If you wish to know more about N690, well, you are in the perfect place. This blog will talk about N690, its benefits, and the top knives made from this steel.
What is N690 Steel?
N690 is a cobalt stainless steel manufactured in Austria by a firm renowned for creating steel that can be made into surgical tools and sharp knives. This kind of steel is extremely identical to 440C steel and contains 1.07 percent carbon. This has carbon that ranges from .95 to 1.07%. This is also considered a high-end type of stainless steel that comes with an alloy which is common in different types of high quality knives. It’s a tough knife that is rust and wear-resistant and also extremely hard steel.
N690 has the vital martensitic chromium steel that has cobalt, vanadium as well as molybdenum. This can also be hardened to an extremely preferred hardness level. Its surface finish is finely polished and ground.
Composition of N690 Steel
The chemical composition of this steel is a bit close to 440C with a similar amount of molybdenum, carbon as well as Chromium. Aside from the three mentioned elements, this steel also comes with vanadium and cobalt to boost its alloy properties. Below are the different elements found in N690 steel.
- Chromium 17.3%: This helps in improving tensile strength, edge retention as well as wear and rust resistance.
- Cobalt 1.65%: This element enhances the individual impact of other included elements in the steel.
- Carbon 1.07%: This is for better toughness and resistance to rust and wear and tear.
- Molybdenum 1.1%: This is for enhanced strength and manufacturing capability or machinability.
- Manganese 0.4%: Ideal for hardness
- Silicon 0.4%: This is for better strength and toughness
- Vanadium 0.1%: This element adds for better toughness and wear resistance as well.
The Benefits of N690 Steel
This kind of steel offers amazing benefits that take account of the following:
Outstanding Edge Retention
Knives made from this kind of steel are renowned for possessing the ideal balance between performance and edge retention. N690 steel is very fine-grained, making a knife that will retain the sharpness of the edge even if you use it many times and on a hard object. All knife experts will tell anyone that is the steel grain is fine; it has amazing retention.
By including elements like cobalt, a very unusually alloying substance, an additional edge is given. Having this kind of element combined combines into N690 makes a rare uniformity offering a consistent and fine edge, improving edge retention as well as sharpening receptivity. It is safe to say the N690 edge holding ability is the best compared to some stainless formulations.
Capability to Sharpen Easily
This steel was formulated and developed with the input of knife manufacturers and companies and the heat treaters and steelworkers, which would influence the steel. It was particularly made to provide the most excellent compromise possible.
The outcome was wear-resistant which can retain machinability. This results in M390 having a good grindability; thus, it can be honed and sharpened with less tool wear as well as expense.
Amazing Corrosion Resistance
This can keep corrosion and rust at bay, although in a wet condition. You can look forward to resistance to harm from too much exposure to cruel elements like moisture, salt as well as humidity. This was made possible due to the inclusion of various elements such as Chromium, vanadium as well as molybdenum.
Incredible Resistance to Wear: The integration of cobalt, a super hard and heat resistant metal, makes the N690 more resistant to corrosion, rust as well as deterioration compared to other steels out there. Even the best and high-quality steel edges are likely to wear in due course, as you utilize them and resharpen those most often.
On the other hand, an N690 edge could last for a lot of years without rusting and wear. This is one of the many reasons why it is chosen and preferred for creating blades for various kinds of activities.
Amazing Cutting Capability: The level of toughness of the N690 steel is perfect for cutting tougher and stronger things compared to paper ones and plastics. You can cut the rope, wood as well as other things with ease.
This steel is relatively hard because of the nickel and high Chromium. This can survive heavy use and heavy impact without breaking, cracking, or chipping with no trouble.
Get Rid of Stains and Rust
By mixing different alloying elements such as molybdenum, manganese, vanadium, Chromium, and many others, this steel resists corrosion and deterioration like rust due to external elements such as salt, moisture, and humidity.
Another good thing about this steel is that it thrives regardless of the conditions resulting in flawless adaptability- perfect for hunting blades. On the other hand, you should follow proper care to make it last.
