Steel N690 (Н690) Bohler (Bochler) pros and cons: characteristics, properties
The main production facilities of the famous and long-standing tradition of metallurgical production of the Swedish-Austrian concern Böhler – Uddeholm are located in Germany and Austria, but there are several enterprises on the American continent.

N690 steel is used for the production of various high-strength industrial tools, such as drills and cutters. One of the areas of use is the manufacture of knives.

Chemical composition and features of steel
N690 refers to stainless doped martensitic alloys and has a different composition from other brands:

the percentage of carbon in it is quite high and is 1.08%, which gives the metal increased strength and hardness;
chromium (17.30%) increases wear resistance and improves hardening ability, gives the metal anti-corrosion properties;
molybdenum increases the hardness of steel, practically eliminates brittleness and brittleness;
vanadium adds flexibility and increases the ability to protect against aggressive environments;
manganese in the smelting process additionally increases the hardness of steel;
silicon increases the wear resistance and the reliability of preserving the properties acquired by the metal.
Unlike other alloys, N690 contains 1.5% cobalt, which increases the heat resistance of the steel and directly affects its mechanical properties.

As for the name "martensitic", it is named after the creator Mark Martens, who first described the process of forming an unusual metal structure. In such types of alloys, it is acicular in the form of the thinnest plates, located in two variants: parallel to each other or chaotically. It is characteristic of metals that have undergone the hardening procedure.

In the course of its implementation, a component called martensite is formed. Without delving into special terms, it can be called a solid supersaturated solution of carbon in -iron (low-temperature modification of iron).

Advantages and disadvantages of metal
One of the most important characteristics of N690 steel is a high level of resistance to the appearance and spread of corrosion. Under normal conditions, a product made of this alloy is not subject to destructive processes. At the same time, the hardness of the metal increases significantly due to the quenching process.

N690 is used in the production of knives and is considered one of the best materials for their manufacture. The advantages and obvious advantages of N690 steel include:

• high strength and resistance to physical exertion;
• resistance to bending and breaking;
• resistance to breaks and twisting of metal;
• excellent cutting properties;
• preservation of sharpening sharpness for a long time.

As for the disadvantages of Bohler N690 steel, most experts come to the conclusion that this alloy has practically no disadvantages, has an ideal composition and high technical characteristics and properties.

They allow you to use this alloy for the manufacture of various cutting tools, including tactical knives, as well as hunting knives and cutting knives with fixed blades and handles made of natural wood, which can be purchased in the online store https://knife.net.ua/ .

Many connoisseurs of alloys used in the production of knives compare the properties of N690 and American steel 440C. Although they are not analogs, they have some common technical characteristics, which allows it to be used for a cutting tool. The best qualities are especially evident in handmade knives for the kitchen and everyday life, a large assortment of which is presented on the website of the online store https://knife.net.ua/.

WHAT ARE MICARTA AND G10 AND HOW THESE COMPOSITE MATERIALS DIFFER FROM EACH OTHER
For decades, composite materials Micarta and G10 have been recognized as undisputed leaders in the knife industry, in particular for the production of handles of various complexity. The materials are distinguished by their availability, ease of production and processing, as well as high strength, wear resistance and unpretentiousness in maintenance. Both materials are composite, based on polymer resin, which is supplemented with layers of different types of bonded fabric.

Micarta material is an electrical insulating material consisting of a polymer film (based on cresolaldehyde, phenolaldehyde, xylenealdehyde resin, or resin from a mixture of phenolic raw materials). It is glued with the help of various electro-insulating papers, fabric (mainly linen of natural or artificial origin), or other materials of a similar structure, there are also fiberglass and carbon fiber options. The color of the material depends on the resin and fabric base used for gluing. Micarta is a relatively soft material and requires careful manual processing. Therefore, it is used in the production of handles for more expensive knives.

Mykarta is registered as a trademark of the American company Industrial Laminates / Norplex, Inc. (Norplex-Micarta). Its domestic analogue can be considered a material called "getinax", which is mainly used as a basis for printed circuit boards. The material also has a layered pressed structure, which consists of a paper base with the addition of impregnation from phenolaldehyde or epoxy resin.

Linen-based mikarta has a more attractive optical effect during fiber grinding. After finishing the grinding, the surface can be polished or sandblasted. In the first version, the surface of the material will be smooth, silky, warm and pleasant to the touch. And in the second, the material becomes rough and has a matte shade, in addition, it holds securely in the hand and does not slip.

The main properties of Micarta:

• increased water resistance;
• excellent resistance to temperature changes;
• resistance to mechanical processing;
• dense structure that does not absorb odors;
• the microrelief of the material does not slip in the hand even on a wet surface;
• tight fit to the blade, which does not leave gaps at all and prevents food residues and harmful microorganisms from accumulating.

G10 material is a light, hard and fairly stiff composite material with a textured surface, which is mainly used in the manufacture of handles for both folding pocket knives and knives with a fixed blade. This material is created by placing several layers of fiberglass, thoroughly impregnated with epoxy resin, in a special vacuum press, where, under the influence of compression and heat, the resin finally hardens, preserving the structure of the fiberglass.

G10 material is characterized by good impact resistance, wear resistance, moisture resistance, as well as ease of processing and maintenance. The material can be painted in various colors, including layers. The surface of G10 can also be polished to a glossy state, or have a rough anti-slip structure, under the influence of a grinding machine, or sandblasting.

Key features of G10:

• high stability of basic properties, with temperature fluctuations;
• withstands high impact loads, compressive and tensile loads;
• high general hydrophobicity and resistance to chemicals;
• weighs relatively little in relation to overall strength and density;
• low electrical conductivity;
• can take different forms.

Composite materials G10 and Micarta have a practically similar composition and external similarity. At the same time, the G10 material has a higher fire resistance, although it is not a non-combustible material, it has a higher resistance to compression, bending, impact and tearing, and it is also simpler and more economical to manufacture. At the same time, G10 is inferior in terms of "toughness" in wet conditions, and also, tactilely, it feels less "natural".
