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 a 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.

 Ironwood - iron wood - handmade knives

Ironwood - Ironwood

In nature, ironwood is extremely rare, so it occupies an honorable place in the Red Book. However, in its properties, each iron tree is not inferior to the density of cast iron. Its bark can withstand fire from firearms, but at the same time it sinks hopelessly in water. It should be noted that this is not a separate class of trees, but a whole group collected 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's special about these trees?

It is quite difficult to recognize the “stone” species 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 centenarians is at least 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 rot fungus;
• the log will definitely go under water, since the density of the wood is 1 t/m³, taking into account the humidity of 12%, for this reason such species 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 ironwood to survive in the harshest climatic conditions. Sudden temperature changes in Russia, African drought or humid European climate cannot harm this natural phenomenon. These types of trees adapt well to any unfavorable environment. To do this, they are equipped with a considerable number of devices, ranging from the unique structure of the trunk/roots to the chemical composition of the bark. In this regard, they are widely used in production:

• furniture;
• building structures;
• cars;
• cosmetics;
• decorative elements;
• underwater technology

Mammoth tusk: a jewel mined in permafrost

Most of our contemporaries are a mammoth - “a monster, mischievous, huge...” A large, disproportionately built elephant. A fierce beast, densely overgrown with dense shiny or long brown and patchy hair. A four-legged hero with heavy tusks at the ready, fearlessly chasing polar bears. Or he runs embarrassedly from a handful of furious bipeds... This is what a mammoth is in the performance of artists from science.
Are mammoths extinct?

It is generally accepted that mammoths lived as long ago as dinosaurs. However, scientists have reliably established that the last herds of mammoths lived on Wrangel Island about three and a half thousand years ago. The Pyramid of Cheops was already more than a thousand years old by that time. Moses was just preparing his fellow tribesmen for a forty-year dessert trip. The Mediterranean volcano Santorini, having exploded, buried the Mycenaean civilization a hundred years ago.

These are herds; individual families of mammoths, according to lovers of circumpolar hunting solitude, exist safely to this day. Whether this is true or not is unknown for sure. However, there is no doubt that in the past mammoths lived everywhere in Europe, Asia, and America.

Permafrost is the best refrigerator for mammoth bones

The mammoth bone cemetery is everywhere: in France, in the Czech Republic, in Ukraine. But only where the earth has been in a state of permafrost for thousands of years is a mammoth ivory kept in its original (or almost original) form. One of the largest burial sites in the world is Yakutia, where large quantities of this highly valuable material are still mined annually. According to experts, potential resources in the North Yakutsk province may be about 450 thousand tons.

Man at all times highly valued the fossil mammoth tusk. Dense, strong, massive, often white, usually yellowish, often colored with natural color by mineral salts, mammoth bone has been used for many centuries as a raw material for bone carving.

A material that is worthily appreciated by kings and rulers all over the world!

Tsar Alexei Mikhailovich, the father of Peter the Great, introduced a state monopoly on mammoth ivory back in the mid-seventeenth century. On his initiative, the extraction and supply of mammoth ivory to the bone-carving workshops of Kholmogory and Moscow (Armory Chamber) became permanent.

Peter the Great, fascinated by crafts, carved a snuff box from mammoth bone with his own hands. Foreign craftsmen also liked the material: among the goods traditionally supplied from Russia to the West, there was always a place for the bone of an extinct animal.

The only one allowed

Today, mammoth ivory is the only highly valuable bone material allowed for extraction and use. Elephant tusk, the well-known ivory, has been classified as a prohibited material. Similar decisions were made regarding the sperm whale tooth (due to the complete abandonment of whale hunting) and walrus tusk (which is caught by northern peoples in small quantities).

Moose antler and stream (the tubular femur of large animals) are not capable of producing the visual effect produced by mammoth bone products. The internal glow of the figures, the warm shades of the living body, the unsurpassed plasticity of the smallest details - these are just some of the advantages inherent in mammoth tusk.

Versatility, nobility, uniqueness

The physical qualities of the mammoth tusk massif are unique. Modern technologies are only trying to create substances with properties approaching natural mammoth bone. Allowing for the finest elaboration of details, making it possible to create the illusion of soft draperies of clothing that naturally fall, mammoth tusk has deservedly become the most sought-after material for bone carving.

Mammoth ivory with a homogeneous structure is in particular demand. The uniform coloring of the bone mass, the absence of cracks and other defects allows the artist to create without taking into account the quality of the material. However, the integrity of a solid mammoth bone is already rare and defects in the material force the artist to be more inventive in composition, which ultimately turns into an additional advantage in sculpture.
