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).

 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.
