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
According to 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% 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 N690 steel allows for 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 deliveries
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.
It is worth remembering that when using a knife for its intended purpose and with careful handling, the knife will serve you for a very, very long time.

Ironwood - iron wood - handmade knives
In nature, ironwood is extremely rare, therefore it occupies an honorable place in the Red Book. However, in terms of its properties, each iron tree is not inferior to the density of cast iron. Its bark can withstand gunfire, but it sinks hopelessly in water. It is worth noting that this is not a separate class of trees, but a whole group assembled from different species. It includes several dozen species of plants with unusually dense wood. They can be found on every continent. Moreover, raw materials are used both in the industrial industry and in medical practice.
What is special about these trees?
With the naked eye, it is quite difficult to recognize the "stone" breed of a perennial plant. Especially if they are on the verge of extinction. However, they are characterized by the following features:
- the age of such long-lived people is not less than 2 hundred years;
- wood fiber is resistant to corrosion processes and does not deteriorate under the influence of strong acids;
- the bark contains many tannins that protect their "hosts" from all kinds of parasites, as well as from the rot fungus;
- the log will definitely go under water, since the density of wood is 1 t / m³, taking into account the humidity of 12%, for this reason, such breeds grow quite slowly;
- the height of each exceeds 25 meters, and the girth of the trunk reaches more than 200 cm.
All these properties are necessary for an iron tree to survive in the harshest climatic conditions. Sharp temperature changes in Russia, African drought or humid European climate will not be able to harm this natural phenomenon. Such varieties of trees perfectly adapt to any adverse environment. For this, they are equipped with a considerable number of devices, starting from the unique structure of the trunk / roots and ending with the chemical composition of the bark. In this regard, they are widely used in production:
- furniture;
- building structures;
- cars;
- cosmetics;
- decorative elements;
- underwater equipment.
High-quality and original steel overlays are a wonderful decoration of exclusive and unique knives of the workshop Studio of handmade knives - VLADA VELYCHKA (Ukraine), which offers to order and buy online store https://knife.net.ua
