Features of steel N690
Martensitic alloy steel N690 is produced by the Vohleg-Uddeholm Gmbh&C corporation, which has its enterprises in Austria, Germany, South and North America. Another name for the alloy is Austrian cobalt stainless steel. Due to its high quality and operational characteristics and advantages, it is successfully implemented in many countries of the world for the manufacture of knives and other purposes.
Steel is produced by electroslag smelting technology. It has a uniformly distributed carbide structure of the crystal lattice in the absence of harmful impurities. As a result of heat treatment and forging, the impact toughness of the material increases without loss of hardness. The presence of alloying additives in the chemical composition of steel ensures resistance to corrosion.
Field of application
Steel is recognized as a good material for serial production of long-range and tactical knives, the technical characteristics of which allow operation in difficult and extreme conditions. Blades made of N690 steel are able to withstand not only longitudinal, but also strong lateral loads when acting on bends and twists.
Due to its resistance to corrosion and aggressive environments, steel is used in the manufacture of diving knives, harpoons for spearfishing and other sports equipment.
This steel is used in the manufacture of knives by such well-known European brands as Vokeg, Spyderco, Vepshmade and Echthema Ratio. Manufactured blades have excellent cutting properties, are strong, durable, sharpen well and hold an edge. The presence of alloying elements in the composition ensured high corrosion resistance while maintaining plasticity. If necessary, there is a possibility of thermal hardening up to 60 NKR.
The technical and physical characteristics of the alloy allow it to be used in mechanical engineering for the manufacture of tools, milling cutters, drills, parts of bearings and relevant components operating under high mechanical loads. The steel is highly wear resistant and can be heat treated.
Resistance to the effects of moisture and chemicals allows the use of steel in the food and pharmaceutical industry for the manufacture of cutting tools and grinders. At the same time, the ecological purity of the material and the complete absence of impurities are taken into account.
ANALOGUES
In terms of its composition, steel N690 is a close analogue of Russian steel 95X18, German X102SgMo17, Japanese / (3-10 and A115-10, French 2100СО17, American 440 С. In Sweden, an analogue of Sandvic 12С27 is produced).
Storage
Steel N690 contains:
■ 1.08% of carbon (C), which gives the material hardness and increases strength;
■ 17.3% chromium (Cg) to obtain anti-corrosion properties, increase wear resistance and change hardening conditions;
■ 1.1% molybdenum (Mo) to reduce brittleness, increase plasticity and resistance to high temperatures;
■ 0.1% vanadium (V) to increase metal elasticity and inertness to aggressive media;
■ 1.5% cobalt (C) increases heat resistance and improves mechanical properties;
■ 0.4% manganese (Mp) increases hardness;
■ 0.4% silicon (5|) to improve alloy stability and increase wear resistance.
The presence of cobalt in the chemical composition of the metal makes the crystal structure of N690 more uniform and resistant to mechanical loads.
PROS AND CONS OF N690 STEEL FOR KNIVES
The use of Austrian steel N690 allows the production of high-quality stainless knives for various purposes. Due to its physical and technical properties, the material is well processed, capable of heat treatment, is not prone to corrosion and is sold at an affordable price.
5*ee1 N690 is one of the best alloys for making beautiful wear-resistant blades. Simple sharpening and long-term preservation of the sharpness of the edge make use simple and convenient. You will never regret buying or making a knife from this steel.
Types of supplies
The high quality of Wohler N690 steel is ensured by the use of a unique rolling technology developed by the manufacturer. Metal sheets are subjected to repeated hot processing with rolling in the longitudinal and transverse directions. After that, the material is cold cut into strips.
N690 steel is supplied to the rolled metal market in the form of steel strips 3-5 mm thick, 20-50 mm wide and 250 to 1000 mm long, especially for the manufacture of knives. The cross-section of the strips is rectangular or with a prepared longitudinal bevel, which eliminates the need for blacksmithing when making the blade. The steel may or may not have previous heat treatment.
All of this is very convenient, as it does not require operations to cut large sheets, which allows you to accurately determine the amount of necessary material and reduces the amount of waste.
Strips are sold individually. The price depends on the geometric dimensions of the product, thicknesses and types of preliminary factory processing. For the products of the metalworking industry, we supply a sheet 2-8 mm thick, the size stated in the contract. If necessary, you can order any analogue of steels of type N690. Sheet metal is sold by weight.

WHAT ARE MICARTA AND G10 AND HOW THESE COMPOSITE MATERIALS DIFFER FROM EACH OTHER
For decades, Micarta and G10 composite materials have been 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 captive fabric.
Micarta-G10-Composite-materials-photo-2
Micarta material is an electrical insulating material consisting of a polymer film (based on cresolaldehyde, phenolaldehyde, xylenolaldehyde resin, or resin from a mixture of phenolic raw materials). It is glued with the help of various electrically insulating papers, fabric (mainly linen of natural or artificial origin), or other materials of a similar structure, there are also options made of fiberglass and carbon fiber. 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.
Micart 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 sheet pressed structure, which consists of a paper base with the addition of phenolaldehyde or epoxy resin impregnation.
Linen-based micarta has a more attractive optical effect when sanding the fibers. After grinding, the surface can be polished or sandblasted. In the first option, 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, besides, it is securely held in the hand and does not slip.
Main characteristics of Micarta:
increased water resistance;
excellent resistance to temperature changes;
strength to mechanical processing;
dense structure that does not absorb odors;
the micro-relief of the material does not slip in the hand even when the surface is wet;
tight fit to the blade, which leaves no 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 of 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.
The 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 different colors, including in 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 the G10:
high stability of basic properties during temperature fluctuations;
withstands high shock loads, compressive and tensile loads;
high overall hydrophobicity and resistance to chemicals;
weighs relatively little, in relation to the overall strength and density;
low electrical conductivity;
can take different forms.
Composite materials G10 and Micarta have almost the same composition and external similarity. At the same time, the G10 material has higher fire resistance, although it is not a non-flammable material, it has higher compressive, bending, impact and tear strength, and it is also simpler and more economical to manufacture. At the same time, G10 is inferior in terms of "stickiness" in wet conditions, and also, tactilely, it feels less "natural".
Wood species for knife handles
Stabilized hornbeam imitates the texture of ebony wood.
Ebony is one of the most valuable species of wood growing in Africa. The high price is due to the rarity of the breed, the fact that the wood has a large amount of sapwood (the layer of wood between the bark and the core), which allows you to use only about 30% of the trunk for products. In addition, ebony is prone to cracking, which is unacceptable for a knife handle. Black hornbeam, thanks to impregnation with resins, repeats the texture of ebony and is not prone to cracking, in addition, hornbeam handles are extremely strong due to the high density of wood, which makes it an ideal material for making knife handles in black color.
In the photo (left-right): ironwood, resin-stabilized hornbeam bar, stabilized hornbeam handles.
Wenge is a tropical type of wood that is often used to make knife handles, not only because of its beautiful structure, but also because of its physical properties. It is characterized by an extremely coarse texture with straight veins. It has extremely high impact resistance, which will allow the handle to last as long as the knife blade. Resistant to decay. The color scheme can vary greatly from golden brown to dark brown with black veins, for the manufacture of knife handles blanks from the core of the trunk are used.
Bubinga or otherwise African rosewood has a beautiful and extremely rich structure with beautiful veins of pink and red. The sapwood of a tree is suitable for the handles, in this case, the only difference will be the color, the sapwood is a few shades lighter. Extremely dense (from 800 to 960 kg/m3) and heavy type of wood, but Bubing handles look thorough and solid. Not prone to cracking, good resistance to moisture and fungus.
Paduk is an extremely common tree in the southern hemisphere. One of the most water-resistant types of wood (when in contact with the soil, it can last an average of 25 years), it is well suited for knives for fishing, hunting in rainy and humid weather, because it does not slip in the hand, even when wet.
In the photo (left-right) handles made of: bubingu, wenge, paduka.
One of the oldest materials for making knife handles is bone and animal horns . Like wood, the material is natural, moose horn is most often used for knife handles. A very difficult material for processing compared to wood, but sheepskin is worth the effort, the handles are exclusive and not similar to each other, if a huge number of handles can be made from a tree trunk, then a very limited number can be made from the horn of one moose.
When ordering a knife with a handle made of elk horn, you should understand that it may differ slightly from the one you see in the photo, here, just like with human fingerprints, no two are exactly the same.
The only disadvantage of this material can probably be considered only the inconvenience of using it for hunting in winter, in the cold the horn handle gets very cold and it will be very uncomfortable to hold it with a bare hand.
Birch is practical and convenient as a material for the handle, its main advantage will be that the handle does not slip in the hand, even if a large amount of water has fallen on it. Well, of course, birch is native to us, not wood from Africa and the tropics. Birch typically contains a large amount of tar, which gives it disinfectant properties and protects it from rotting, no parasites and fungi will take root on birch. Extremely good material, for fishing knives, a small knife with a birch handle, can stay afloat after entering the water.
Sapale is another type of wood originally from Africa. Extremely beautiful palette structure from light pink to reddish-brown color. It is not prone to cracking and has a high hardness, from 4.1 to 4.5 Brinell units. All types of wood presented on the site are great for making knife handles and mostly the choice of a knife with a specific handle has an aesthetic value, depending on your personal preferences.
In the photo (left-right) handles made of: elk horn, birch, sappel.
Handles can also be made of several types of wood, with "senvdych" inserts next to the guard of the knife, or in the middle of the handle. All types of wood presented on the site are great for making knife handles and mostly the choice of a knife with a specific handle has an aesthetic value, depending on your personal preferences.
High-quality and original steel inserts are a wonderful decoration of exclusive and unique knives of the Studio of exclusive handmade knives Fomenko Knifes (Ukraine), which offers to order and buy online store https://knife.net.ua
