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.

Ironwood - iron wood - handmade knives

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?

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.

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.

WHAT ARE MICARTA AND G10 AND HOW THESE COMPOSITE MATERIALS DIFFER FROM EACH OTHER

For decades, Micarta and G10 composite materials have been undisputed leaders in the knife industry, in particular for the production of handles of various complexity. The materials are distinguished by their availability, ease of production and processing, as well as high strength, wear resistance and unpretentiousness in maintenance. Both materials are composite, based on polymer resin, which is supplemented with layers of different types of captive fabric.

Micarta-G10-Composite-materials-photo-2

Micarta material is an electrical insulating material consisting of a polymer film (based on cresolaldehyde, phenolaldehyde, xylenolaldehyde resin, or resin from a mixture of phenolic raw materials). It is glued with the help of various electrically insulating papers, fabric (mainly linen of natural or artificial origin), or other materials of a similar structure, there are also options made of fiberglass and carbon fiber. The color of the material depends on the resin and fabric base used for gluing. Micarta is a relatively soft material and requires careful manual processing. Therefore, it is used in the production of handles for more expensive knives.

Micart is registered as a trademark of the American company Industrial Laminates / Norplex, Inc. (Norplex-Micarta). Its domestic analogue can be considered a material called "Getinax", which is mainly used as a basis for printed circuit boards. The material also has a sheet pressed structure, which consists of a paper base with the addition of phenolaldehyde or epoxy resin impregnation.

Linen-based micarta has a more attractive optical effect when sanding the fibers. After grinding, the surface can be polished or sandblasted. In the first option, the surface of the material will be smooth, silky, warm and pleasant to the touch. And in the second, the material becomes rough and has a matte shade, besides, it is securely held in the hand and does not slip.

Main characteristics of Micarta:

increased water resistance;
excellent resistance to temperature changes;
strength to mechanical processing;
dense structure that does not absorb odors;
the micro-relief of the material does not slip in the hand even when the surface is wet;
tight fit to the blade, which leaves no gaps at all and prevents food residues and harmful microorganisms from accumulating.
G10 material is a light, hard and fairly stiff composite material with a textured surface, which is mainly used in the manufacture of handles of both folding pocket knives and knives with a fixed blade. This material is created by placing several layers of fiberglass, thoroughly impregnated with epoxy resin, in a special vacuum press, where, under the influence of compression and heat, the resin finally hardens, preserving the structure of the fiberglass.

The G10 material is characterized by good impact resistance, wear resistance, moisture resistance, as well as ease of processing and maintenance. The material can be painted in different colors, including in layers. The surface of G10 can also be polished to a glossy state, or have a rough anti-slip structure, under the influence of a grinding machine or sandblasting.

Key features of the G10:

high stability of basic properties during temperature fluctuations;
withstands high shock loads, compressive and tensile loads;
high overall hydrophobicity and resistance to chemicals;
weighs relatively little, in relation to the overall strength and density;
low electrical conductivity;
can take different forms.
Composite materials G10 and Micarta have almost the same composition and external similarity. At the same time, the G10 material has higher fire resistance, although it is not a non-flammable material, it has higher compressive, bending, impact and tear strength, and it is also simpler and more economical to manufacture. At the same time, G10 is inferior in terms of "stickiness" in wet conditions, and also, tactilely, it feels less "natural".
