Powder steel S390 MICROCLEAN
Powder steel S390 MICROCLEAN is a powder metallurgical high-speed steel of the third generation, which is made from exceptionally clean finely dispersed powder produced at the modern plant for the production of high-quality powder steels BÖHLER in Kapfenberg, Austria.
This alloy is expensive, belongs to the premium class with high hardness and complex mechanical and heat treatment. As a result, its hardness can reach up to 67-70 units according to Rockwell, which is distinguished by an aggressive cut and high operational characteristics.
Powder steel S390 is widely used for the production of high-performance tools (for example, in the automotive industry - clutches, camshaft flywheels; in metal cutting - drilling, thread cutting, gear cutting tools, broaching and broaching, end mills, saws; in cold metal working - various types of spindles thread knurling tools, etc.), i.e., where the high precision of the components is important, as well as the stability and duration of its use, therefore, the composition contains many alloying elements, the action of which is aimed at preserving the properties of steel in any conditions.
Also, S390 steel has proven itself in knife production, although not so long ago. From S390 steel, you can buy high-quality and reliable working and hunting knives of medium and small size, which will show themselves perfectly in cutting strong materials, for example, tendons and skins when processing game. Similar characteristics will be relevant for professional kitchen knives.
The production process of powder steel S390 MICROCLEAN looks like this:
The chemical composition of S390 MICROCLEAN steel is as follows:
- Carbon (C) is responsible for strength after heat treatment, i.e. provides hardness and strength;
- Chromium (Cr) - increases the hardening ability of steel, has a positive effect on corrosion resistance. In this alloy, the chromium content is small, so the knife blade requires care to protect it from rust. Chromium also increases wear resistance;
- Molybdenum (Mo) - allows you to increase the melting point, therefore, and preserve the quality of the blade at elevated temperatures. At the same time, the sword does not become fragile and fragile, with increased hardness - the steel becomes more elastic, resistance to chemical aggressive substances increases;
- Vanadium (V) – its presence indicates an increase in elasticity, wear resistance, and also provides inertness to chemical influences;
- Tungsten (W) – the high melting point of tungsten increases the stability of steel at high temperatures. It is the main alloying element of high-speed cutters;
- Cobalt (Co) is an expensive alloying additive that has a positive effect on heat resistance, also increases the hardness and wear resistance of the metal, while these parameters are preserved at high temperatures and mechanical loads.
Thus, the advantages became as follows:
- high red resistance, the steel behaves well during tempering, while it works without problems even at low temperatures;
- very high wear resistance;
- excellent compressive strength;
- high viscosity; impact properties;
- knives made of S390 steel have good machinability indicators, for example, grinding;
- good fatigue properties.
There are fewer disadvantages, but they are still there:
- corrosion resistance is not at the highest level, so the knife needs additional care, albeit minimal - wipe with petroleum jelly, which is sold in any pharmacy;
- high price due to the complexity of steel production.
- A knife made of powder steel S390 Microclean is certainly not a cheap pleasure, but it is worth it and will be useful both for professional activities and for active hobbies, whether it is hunting, fishing, tourism or cooking.
*It should be remembered that if the knife is used for its intended purpose and with careful handling, the knife will serve you for a very, very long time.

The crown and crown of an oak tree
Kap and souvel are growths on the trunks of trees in the form of characteristic rounded swellings. Getting such a blank is a dream for everyone who works with wood, and here's why. The fibers in such growths have a special deformed structure: their tortuous and disordered growth creates a unique texture called swill. But this is not the flexibility characteristic of, for example, maple. It is very tangled in growth and has a number of features, thanks to which an incomparable wooden texture is obtained. With its pattern and characteristic ebb, it resembles marble, mother-of-pearl or moire pattern. Such material is a real treasure for everyone who works with wood.
Cap and souvel are similar in nature, but they are not the same. They differ in structure, textured pattern, features of formation and a number of other points that we have collected in this table.
Capt
People call the cap a "witch's broom". It really has something repulsive, but only if you don't know what miracle nature has hidden under a thick layer of bark.
What does Capt
Location on the tree
Unlike the souvel, mouthpieces are rare. They usually appear on the trunks of trees or in the basal part. They are much less often formed on branches. Basal growths (caproot) have a flattened shape, while trunk or bud growths are more like a ball, often asymmetrical in appearance. As a rule, mouthpieces are located on one side of the trunk as a characteristic influx; growths that cover the tree all the way around are less common. There are both single specimens and whole cap colonies covering the trunk of the tree in small groups.
Formation and structure
The fundamental difference between a cap and a souvel is in the structure. If you look at the cap in section, it will be filled with small wooden knots - these are the so-called kidneys. Whereas souvel is simply deformed and chaotically intertwined annual rings. Thus, the cap growth represents a kind of reserve bundle of kidneys that have not opened, created by nature as a reserve. Why? Dendrologists do not agree on this.
Under a thick layer of bark, cap and souvel practically do not differ from each other. The only thing that can give off a cap is small green twigs growing on its surface. This is a part of the same sleeping kidneys that have only been activated for some reason. Without the bark, the difference between cap and souvel becomes obvious. The surface of the cap is covered with cone-shaped convexities, while the souvel is completely smooth.
Dimensions
The sizes of the drops vary greatly: from growths of walnuts to truly gigantic formations. The largest of the documented kapa on the territory of the former USSR was found on the bank of a flat-leaved tree that grew on Sakhalin. Its height was 1.4 m, and the length of the circle was 10.8 m. The size of the tips depend on the location on the trunk and the type of tree. The largest are traditionally considered the basal kapa, but their extraction turns into a difficult task and is impossible without cutting down the tree. Large mouths, weighing 300 kg or more, can often be found on walnut, downy river, Mongolian oak. They grow 3-4 times slower than the souvel and are very rare.
Texture
Kapa wood has a characteristic texture, thanks to which it is quite easy to distinguish it from suvel. On the cut, the dormant buds seem to be wrapped in numerous layers of wood fibers. Such nodules are somewhat similar to the "bird's eye" texture, but they are not so evenly distributed in the cap. Here everything is chaotic: the kidneys merge with each other, penetrate into each other, are absent in some areas, and in others they accumulate very densely. All this creates complex lacy abstractions that somehow resemble a malachite pattern.
Bird's eye (maple sapwood) and cap texture
The more dormant buds, the more complex and rich the pattern of the wood. In large kapa there are fewer kidneys, so their texture is closer to suvels.
Biological role of caps
Both kapa and souvel are often called a disease. Such a position is not completely scientific, but it cannot be called unequivocally wrong either, at least because the biological role of growths is still not understood. There are different hypotheses about this. For example, the cap is considered as a reserve supply of kidneys from which the tree can regenerate, for example, in case of drought or partial loss of the crown. There is also an opinion that the growths increase the mechanical strength of the trunk, protect it from damage or prevent disease-causing agents from getting inside. There are many assumptions, and all of them are convincing to varying degrees. However, most dendrologists agree that the ability of trees to form crowns has no clear function — it is a kind of side effect of evolution that was once more important than it is now.
Suvel
Suvel is growths without dormant buds. Sometimes such formations are called "suvelval" or simply "svil". Unlike the kapa, the structure of the souvel has no wooden knots, and all the beauty of the texture here is created by chaotically intertwined vessels. From such deformed fibers, an influx in the form of a ball or a drop is formed on the barrel. It grows three to four times faster than kapa and is found on trees much more often.
What does the souvel look like?
It is quite easy to distinguish a souvel from a cap. Neither small twigs nor buds break through it. Under a strong layer of bark, the surface is completely smooth, without conical bulges, as in a cap. All the beauty of the texture here is formed by the chaotic release of interwoven fibers. It does not just go in light waves, as in some species of trees, but is lost in dense folds, bundles, bundles. All the beauty of the pattern is enhanced by a special ebb that resembles marble, mother-of-pearl or a moiré pattern. There are no such pronounced overflows in the cap.
Suvel changes its appearance more strongly after decoration. For example, with deep impregnation with colorless oils and careful polishing, wood acquires a special "bone" texture. Because of this, souvel is sometimes even called a wooden bone. In some rocks, after processing, the veins are literally visible through the structure of the material. This effect is highly appreciated by knife makers: most often they make knife handles from birch, walnut, and ash sapwood.
The density of the souvel is lower than that of the cap. In this, it significantly exceeds the hardness of the trunk wood. Processing birch sapwood and other species requires certain skills, because, like sapwood, it is not the most pliable material. But despite all the difficulties, working with him is an incomparable pleasure. Souvel is always a mystery: it is impossible to predict that some amazing beauty of the drawing will be revealed after the next pass of the cutter.
