Steel M390: composition, interpretation and application


Damascus steel has long been a leader in strength, reliability and durability. Modern technologies have made it possible to obtain a new type of material that has the best performance - M390 steel. It was first introduced in Austria by Bohler-Uddeholm AG in the early 1990s.

Due to its high technological characteristics, the material was quickly recognized and began to be used for the manufacture of knives. Its main properties include:

  1. Hardness (60-62 HRC) due to the unique structure of the crystal lattice with a solid structure. This result was obtained on the basis of careful adjustment of the composition and ratio of components. M390 steel is hardened, which significantly increases its strength.
  2. The use of vanadium and tungsten. Sharpening of knives is carried out by means of desktop sharpening units, because. the use of water stone will lead to a significant complication of the process. After this treatment, the knife remains sharp for a long time.
  3. The possibility of mirror polishing due to the high hardness of the alloy. The smooth polished surface of M390 steel is characterized by the same reflectivity as a mirror.

Decoding and chemical composition
To date, the composition is widely used for the manufacture of cutting objects, including knives. It belongs to the materials of the powder production method; during its processing, raw materials are crushed and baked in molds when heated to 1500 degrees. This allows the use of a significant part of the alloying elements, which improves the characteristics of M390 steel.

The development of the metal was carried out on the basis of EU standards, according to which the chemical composition of M390 steel, in addition to iron, includes:

  • Carbon in the amount of 1.85±0.05%. It is necessarily present in high hardness metal, binding Ferrum (Fe) molecules to improve mechanical properties. On the other hand, its presence impairs workability and increases brittleness. However, steel is considered the optimal material in terms of brittleness to strength.
  • Chromium is contained in steel in the amount of 20±1%. It is designed to improve mechanical performance and corrosion resistance as a result of heat treatment. With an increase in the concentration of this chemical element in M390 steel, an extension of the period of no-failure operation under cyclic loading and abrasive action is guaranteed.
  • Silicon and manganese are contained in the metal in the amount of 0.7±0.1% and 0.25±0.05%, respectively. They are deoxidizers that prevent airborne chemicals from entering the alloy during manufacture. Due to them, chemical segregation is reduced, strength and surface quality are increased.
  • Molybdenum and vanadium are contained in amounts of 1% and 3-4%, respectively. They are characterized by a high melting point, which increases the resistance of the material to elevated temperatures, stiffness and improves technical properties.
  • Tungsten in steel in the amount of 0.6±0.1%. It increases its strength and has a maximum impact on this indicator compared to other components.

Material Features

 

Alloy benefits include:

  • excellent plasticity with significant hardness;
  • corrosion resistance, inability to oxidize in air and at t = 800 degrees;
  • lack of response to exposure to many acidic and alkaline substances;
  • preliminary heat treatment, which includes hardening and high tempering;
  • strength, providing destruction at a significant load, 1.4 times higher than that of high-speed steels. There is virtually no difference between yield strength and tensile strength;
  • knives from M390 remain sharp for a long time.
  • The only drawbacks can be considered only the cost of the material, the complexity of sharpening and grinding.

Knife from M390

Specifications
Steel M390 is characterized by the following main parameters:

  • melting point 1300-1400 degrees;
  • hardness 65 units. according to Rockwell;
  • ultimate strength 900 MPa;
  • the beginning of the destruction of 850 MPa.


Application
The alloy is used for the manufacture of blades for knives, instruments used in surgery, industrial cutters. Knives are characterized by high hardness and the ability to withstand strong dynamic impacts. They remain sharp for six months, subject to the rules of operation. The only negative qualities include the difficulty of sharpening, which will require special equipment - a grinding machine. It is also important to have skills in this process.

Analogues

Only the American product Duratech 20CV can be considered an analogue of M390 steel, which is due to the recent appearance of the metal on the market.

I also recommend looking at the following steel grades:

40HN;
12X18H10T.

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?

підлога з залізного дерева

It is quite difficult to recognize the "stone" breed of a perennial plant with the naked eye. 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.

величезний стовбур

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.
