Steel DI103-MP (P12M3K5F2-MP). Composition and properties.
Steel brand DI103-MP (Р12М3К5Ф2-MP) is high-speed powder steel from the Ukrainian company Dniprospetsstal (Zaporizhia). If we decipher the name itself, then D is a manufacturing plant, I is an experimental plant, and MP is powder metallurgy. The main purpose of Art. DI103-MP: shaped cutters, drills, countersinks, reamers, milling cutters, etc. for processing high-strength, heat-resistant steels and alloys. The hardness of DI103-MP steel is 64-66 HRC or slightly higher. The microstructure is uniform. It is considered a very good steel for the production of designer knives and blades. It has good wear resistance and satisfactory impact strength. Holds sharpening very decently, gives an interesting aggressive cut. Due to its low corrosion resistance, the DI103-MP knife blade requires attention and care.
I don't know where the myth came from that DI103-MP has not been produced since the time of the USSR - this respected steel is made in Ukraine, from where it was successfully sold and is sold in many countries of the world.

PROPERTIES OF STEEL ELEMENTS:
Carbon (C, Carbon): improves edge retention and increases viscosity; increases hardness and wear resistance; reduces plasticity; in high values, it reduces corrosion resistance.
Chromium (Cr, Chromium): increases hardness, tensile strength and density; increase corrosion resistance (>11% makes the alloy stainless).
Manganese (Mn, Manganese) : increases flammability, wear resistance and viscosity; used as a deoxidizer and degasser to remove oxygen during metal melting; in large % increases hardness and brittleness.
Molybdenum (Mo, Molybdenum) : increases hardness, strength, calcination and density; improves machinability and corrosion resistance.
Nickel (Ni, Nickel): adds impact toughness; improves corrosion resistance; reduces hardness.
Phosphorus (P, Phosphorus): is considered a harmful impurity. It dissolves in ferrite, due to this, the strength increases, but the plasticity and impact strength decrease with an increase in the susceptibility of steel to brittleness. In low-alloy steels with about 0.1% carbon, phosphorus increases strength and resistance to atmospheric corrosion. It is considered a harmful impurity.
Silicon (Si, Silicon) : increases strength; used as a deoxidizer and degasser to remove oxygen during metal melting.
Sulfur (S, Sulfur): is usually considered a harmful impurity that affects plasticity, impact toughness, weldability, corrosion properties, surface quality of steel, etc. The harmful effect of sulfur reduces the presence of manganese in steel. The sulfur content in quality steels does not exceed 0.02-0.03%.
Vanadium (V, Vanadium): increases strength, wear resistance, increases density and viscosity; increases corrosion resistance by increasing the oxide film; vanadium carbide inclusions are very hard.
Tungsten (W, Tungsten): adds strength, viscosity and improves firing; retains hardness at high temperatures.
Cobalt (Co, Cobalt): increases strength and hardness, allows hardening at higher temperatures; enhances the effects of other elements in complex steels.
Niobium (Nb, Niobium) : limits the growth of carbides; limits workability; creates the hardest carbides.
Nitrogen (N, Nitrogen) : used instead of carbon in the steel matrix (nitrogen atoms function similarly to carbon atoms, but have advantages in corrosion resistance).

Features of steel N690
Martensitic alloy steel N690 is produced by the corporation Vohleg-Uddeholm Gmbh & Co. , which has its enterprises in Austria, Germany, South and North America. The second name of 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 the serial production of long 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. The 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, bearing parts and critical 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.
COMPOSITION
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 the action of aggressive environments;
■ 1.5% cobalt (Co) 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 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 direction. After that, the material is cold cut into strips.
N690 steel is supplied to the rolled metal market in the form of steel strips with a thickness of 3-5 mm, a width of 20-50 mm and a length of 250 to 1000 mm, 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, allows you to accurately determine the amount of required material and reduces the amount of waste.
Strips are sold individually. The price depends on the geometric dimensions of the product, thickness and types of preliminary factory processing. For the products of the metalworking industry, the supply of a sheet with a thickness of 2-8 mm of the size declared in the contract is carried out. If necessary, you can order any analogue of steels of type N690. Sheet metal is sold by weight.

Stabilized whale vertebra
Whales have the so-called spongy skeleton. The spine of cetaceans consists of four sections: short cervical (its length is 15 cm and consists of 7 vertebrae), thoracic, lumbar and caudal. Intervertebral discs give the spine flexibility and great mobility. The pectoral fin rests exclusively on the short humerus.
Ironwood - iron wood - handmade knives
Ironwood - Iron tree
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.
