M390 steel: composition, interpretation and application

 

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

Thanks to its high technological characteristics, the material quickly gained recognition 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 crystal lattices with a solid structure. Such a result was obtained on the basis of careful checking of the composition and ratio of components. M390 steel can be hardened, which significantly increases its strength.
  2. Use of vanadium and tungsten. Knives are sharpened using desktop units, because The use of water stone will significantly complicate the process. After such processing, the knife remains sharp for a long time.
  3. The possibility of mirror polishing due to the high hardness of the metal. The smooth polished surface of M390 steel is characterized by the same reflective ability as a mirror.

Decoding and chemical composition

Today, the composition is widely used for the manufacture of cutting objects, including knives. It refers to the materials of the powder method of production, during its processing, raw materials are crushed and baked in molds at a temperature of up to 1500 degrees. This allows the use of a significant part of alloying elements, which improves the characteristics of M390 steel.

Metal development 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 a metal of high hardness, connecting Ferrum (Fe) molecules to increase mechanical qualities. On the other hand, its presence impairs the manufacturability of processing and increases brittleness. However, steel is considered the optimal material in relation to 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 of M390 steel, an extension of the period of trouble-free operation under cyclic loading and abrasive impact is guaranteed.
  • Silicon and manganese are contained in the metal in amounts of 0.7±0.1% and 0.25±0.05%, respectively. They are deoxidizers that prevent chemical elements from the air from entering the alloy during manufacturing. Due to them, chemical treatment is reduced, the strength and quality of the surface is increased.
  • Molybdenum and vanadium are contained in the amount of 1% and 3-4%, respectively. They are characterized by a high melting point, which increases the material's resistance to elevated temperatures, stiffness and improves technical properties.
  • Tungsten steel in the amount of 0.6±0.1%. It increases its strength and has the maximum effect on this indicator compared to other components.

 

Features of the material

The advantages of the alloy include:

  • excellent plasticity with significant hardness;
  • corrosion resistance, inability to oxidize in air and at t = 800 degrees;
  • lack of reaction to the influence of many acidic and alkaline substances;
  • preliminary heat treatment, which includes quenching and high relaxation;
  • strength, which ensures destruction under a significant load, which is 1.4 times higher than the similar indicator of high-speed steels. The difference between yield strength and tensile strength is practically absent;
  • knives with M390 remain sharp for a long time.

Disadvantages can be considered only the cost of the material, the difficulty of sharpening and grinding.

Specifications

M390 steel is characterized by the following main parameters:

melting point 1300-1400 degrees;
firmness 65 of after Rockwell;
strength limit 900 MPa;
the beginning of destruction 850 MPa.

 

Price

The price of M390 blade steel (62 HRC / TCO + cryo-treatment / stonewash / 120 mm) is from UAH 1,900. up to UAH 2947 for 1 piece.

 

Application

The metal is used to make knife blades, surgical instruments, and industrial cutters. Knives are characterized by high hardness and the ability to withstand strong dynamic actions. They remain sharp for six months, subject to compliance with the rules of operation. The negative qualities include only the difficulty of sharpening, for which you will need special equipment - a 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 brands:

  • 40HN  ;
  • 12X18H10T  .


Well, you can buy a knife made of Knife steel CPM-S90V. Composition and properties. on our website knife.net.ua or by contacting us by phone +380961711010

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?

ironwood floor

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.

a huge trunk

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.
