Features of steel N690

Martensitic alloy steel N690 is produced by the corporation Vohleg-Uddeholm Gmbh & Co. , which has its enterprises in Austria, Germany, South and North America. The second name of the alloy is Austrian cobalt stainless steel. Due to its high quality and operational characteristics and advantages, it is successfully implemented in many countries of the world for the manufacture of knives and other purposes.
Steel is produced by electroslag smelting technology. It has a uniformly distributed carbide structure of the crystal lattice in the absence of harmful impurities. As a result of heat treatment and forging, the impact toughness of the material increases without loss of hardness. The presence of alloying additives in the chemical composition of steel ensures resistance to corrosion.

Field of application
Steel is recognized as a good material for the serial production of long and tactical knives, the technical characteristics of which allow operation in difficult and extreme conditions. Blades made of N690 steel are able to withstand not only longitudinal, but also strong lateral loads when acting on bends and twists.
Due to its resistance to corrosion and aggressive environments, steel is used in the manufacture of diving knives, harpoons for spearfishing and other sports equipment.
This steel is used in the manufacture of knives by such well-known European brands as Vokeg, Spyderco, Vepshmade and Echthema Ratio. The manufactured blades have excellent cutting properties, are strong, durable, sharpen well and hold an edge. The presence of alloying elements in the composition ensured high corrosion resistance while maintaining plasticity. If necessary, there is a possibility of thermal hardening up to 60 NKR.

The technical and physical characteristics of the alloy allow it to be used in mechanical engineering for the manufacture of tools, milling cutters, drills, bearing parts, and critical components operating under high mechanical loads. The steel is highly wear resistant and can be heat treated.
Resistance to the effects of moisture and chemicals allows the use of steel in the food and pharmaceutical industry for the manufacture of cutting tools and grinders. At the same time, the ecological purity of the material and the complete absence of impurities are taken into account.
ANALOGUES
According to its composition, steel N690 is a close analogue of Russian steel 95X18, German X102SgMo17, Japanese / (3-10 and A115-10, French 2100СО17, American 440 С. In Sweden, an analogue of Sandvic 12С27 is produced.
STORAGE
Steel N690 contains:
■ 1.08% carbon (C), which gives the material hardness and increases strength;
■ 17.3% chromium (Cg) to obtain anti-corrosion properties, increase wear resistance and change hardening conditions;
■ 1.1% molybdenum (Mo) to reduce brittleness, increase plasticity and resistance to high temperatures;
■ 0.1% vanadium (V) to increase metal elasticity and inertness to the action of aggressive environments;
■ 1.5% cobalt (Co) increases heat resistance and improves mechanical properties;
■ 0.4% manganese (Mp) increases hardness;
■ 0.4% silicon (5|) to improve alloy stability and increase wear resistance.
The presence of cobalt in the chemical composition of the metal makes the crystal structure of N690 more uniform and resistant to mechanical loads.

PROS AND CONS OF N690 STEEL FOR KNIVES
The use of Austrian N690 steel allows the production of high-quality stainless knives for various purposes. Due to its physical and technical properties, the material is well processed, capable of heat treatment, is not subject to corrosion and is sold at an affordable price.
5*ee1 N690 is one of the best alloys for making beautiful wear-resistant blades. Simple sharpening and long-term preservation of the sharpness of the edge make use simple and convenient. You will never regret buying or making a knife from this steel.

Types of deliveries
The high quality of Wohler N690 steel is ensured by the use of a unique rolling technology developed by the manufacturer. Metal sheets are subjected to repeated hot processing with rolling in the longitudinal and transverse directions. After that, the material is cold cut into strips.
N690 steel is supplied to the rolled metal market in the form of steel strips with a thickness of 3-5 mm, a width of 20-50 mm and a length of 250 to 1000 mm, especially for the manufacture of knives. The cross-section of the strips is rectangular or with a prepared longitudinal bevel, which eliminates the need for blacksmithing when making the blade. The steel may or may not have previous heat treatment.
All of this is very convenient, as it does not require operations to cut large sheets, allows you to accurately determine the amount of required material and reduces the amount of waste.
Strips are sold individually. The price depends on the geometric dimensions of the product, thickness and types of preliminary factory processing. For the products of the metalworking industry, the supply of a sheet with a thickness of 2-8 mm of the size declared in the contract is carried out. If necessary, you can order any analogue of steels of type N690. Sheet metal is sold by weight.

What is birch souvel and how is it prepared?

A birch sapwood is an unusual natural formation, which is often called a birch bone among the people. Those craftsmen who specialize in woodworking know the value of this unusual growth. Working with souvel, you can make the most beautiful products with pleasant and high-quality natural characteristics.

What it is?
Suvel is a resource growth for humans, but it does not mean anything good for the birch itself.  This growth appears due to a disease of the tree (to speak figuratively, due to birch cancer).  Usually it is a lump, twisted and woven, does not have a clear geometric shape. Another popular name for growth is svil. And this tree grows 2 or even 3 times faster than the tree itself.

In shape, it resembles a drop, or a ball, or something averaged.  The growth is located around a branch or trunk. On the shore, such formations are often found, although it is impossible to say exactly what they are caused by and why they develop. It is believed that the souvelle appears as a result of the attack of the tree by a fungus. But mechanical injury to the birch cannot be ruled out.

But this outgrowth is called a wooden bone because the cut of the souvelle resembles the separation of marble, with the cross-section and rays characteristic of the material, and the thin particles of the souvelle can even be seen through. Some similarity with the structure of bone tissue, indeed, can be guessed . However, the density of the tissue in the growth is still less - this wood is not as strong as, for example, cap.

It happens that the souvel grows to large sizes. If you come to the Vatican, you can see the font made from a whole piece of souvelle wood cut from a tree . Admittedly, giant size does not equate to quality material. Usually, the smaller the birch bone, the brighter and richer the inner pattern. But in any case, the internal growth pattern is soft, without pincers and needles.

Inside, the souvel resembles mother-of-pearl - by shade, of course.  It is different, it can be whiter, darker, saturated or faded. Sometimes the souvel inside is like amber, it is more brown, pink or even greenish. The shade of the inside of the growth depends on where the birch grows, as well as on the further drying of this part of the tree.

By the way, it is possible to provoke a souvel. Some people simply drag a birch trunk or a specific tree branch with a wire. At the site of the tightening, a bulge is formed, which is created by annual rings. But if caring for nature is a priority, you shouldn't do that.

Suvel is also advantageous due to its natural formation, which behaves well during processing.  The growth is perfectly amenable to grinding, perfectly polished. Finally, the main value of education is the same mother-of-pearl cut that resembles marble. It plays with divorces in the sun, fascinates with its texture and even gives birth to some kind of inner light. It is impossible to say for sure, looking at the growth on the shore, what it is inside, but certain predictions can be made.

The shorter and steeper the growth, the richer and more interesting its internal pattern.

What is different from a cap?
First, it is worth saying what the cap is. It also has an alternative folk name - "witch's broom". This education, unlike souvel, has a benign nature. Nodules grow on a birch trunk or twig. This is not a ball or a big drop, but a nodular formation, with many cones that create sleeping kidneys (or accessory ones). These formations resemble either thorns or bumps. It is not surprising if small shoots and small twigs will grow on the cap, directly from its interior. With silk it is excluded.

The differences between these formations are significant.

For example, a cap is a rare and successful find. It is believed that it can be found on one of 3-5 thousand trees. Souvel is easier to find. On birches, people often find a basal cap, and it can also be of impressive size. Processing a cap is not as easy as a souvel, nevertheless bumps, cones and spikes are visible. But there should be no problems with grinding and polishing.

The wood of suvel is not as strong as that of kapa. It is at least twice as strong as the birch on which the cap grew. Cigarette cases and boxes, earrings, bracelets, pins, and small decorations are often made from caps. But they never create a carved pattern on the mouthpiece (well, maybe only hardened experimenters), because it will be superfluous.

The texture and texture of this rare wooden element does not require excessive decoration.

Features of the workpiece
You must, of course, look for an unusual bulge in the forest. Both cap and svil, by the way, are very often confused with a tree mushroom. It is difficult to even remember its name - Inonotus mowed. But to put it more simply, it is what people call a seagull.

Such a mushroom grows on the shore, and you can find it on a tree more often than a souvel and even more so a cap.

Here are some tips for finding and harvesting silk.

• Silk cutting is optimal in the fall (as well as kapa, however). If they are very clumsy, autumn harvest is especially appropriate.
• It is not easy to cut the growth - you may have to use a chainsaw for this. However, a problem may arise here - saw chains quickly become dull under the influence of stubborn, very strong growth.
• In the absence of a chainsaw, a hand tool is also suitable, but only one with sharp teeth. If the saw is dull, it will be difficult for both the craftsman and the tree, which can be dangerously injured by such manipulations.
• So that an unnecessary hollow does not accidentally form on the tree, the places where the sawdust is cut should be covered with garden wax as soon as possible. Instead of boiling, clay and putty with oil paint will come in handy.
• If a huge layoff is found, you should seriously consider cutting your education. If you remove such a growth from a tree, you can cause severe damage to it: the wound will be so serious that the tree risks dying.
• Initial processing is variable. You can leave wood in the air in the most natural conditions, but natural drying will take a year, or even two. You can speed up the process as follows: the bark is removed from the workpiece, wrapped in a newspaper, and placed in a black polyethylene bag. The paper will prevent the material from heating up quickly, and the bag will create a greenhouse effect. If the souvel dries outside, the black polyethylene will quickly heat up from the sun, if at home - from the battery. The process is uniform, so you don't have to worry about cracking the wood. The package is tied with a small opening. It will take about 25 days for everything.

But harvesting and drying are only the beginning of the process. Next, you need to cook souvel.

Processing secrets

The cooking method described below is quite popular. Moreover, it is suitable to give the wood the desired shade, to force drying, and to make the natural pattern more expressive.

Cooking souveli is made according to a certain scheme.

• Only the peeled workpieces are placed in the pan. They are filled with water so that the liquid covers the material by 3 cm. Then 2 tablespoons of salt are added to 1 liter of water, the container is put on fire. Sawdust is added to the solution: alder or birch are suitable, needles are also useful. They are needed as a natural dye.
• As soon as the water boils, the fire is reduced and cooking continues for 4 hours. If you have to process a very large workpiece - all 6 hours. After that, the water is drained and the wood is left to dry. On the second and third day, the processes are repeated. In total, cooking should take at least 12 hours (up to 18) for three consecutive days.

Why should you cook in salt solution - simple physics works. There is sap in the tree, and its density is lower than the density of the salt solution. During cooking, water enters the material, dehydration begins. Wood sap is forced out, saline solution is absorbed. This is how elemental diffusion of liquid occurs, and the growth is dried.

After cooking, the material should be wrapped in newspaper and sent in a bag. The next day, the soil is still wet, it can dry without unnecessary measures.  In extreme cases, you can dry the material for another day in the newspaper.

Processing of growth is rough and finishing.  With a draft, a cut is made in the material, whatever the future shape of the product is. If it is, for example, a bowl, the inner part is selected from top to bottom. Excess wood is removed by moving from the walls to the center, observing an angle of 45 degrees. A drill or a chisel will help with this. It is not particularly necessary to thin the walls: when they dry, they may turn out to be too fragile, even cracking is possible. When the product is given its original shape, it is left for a couple of days in the open air out of direct sunlight.

Finishing is the removal of clumsiness of forms, the maximum advancement to the final form of the product, the disclosure of the birch bone structure.

If in the course of this work there are defects in the material, small cracks, a mixture of glue and sawdust will help. After that, you can clean off the roughness: with a rasp or scraper, a wire brush also works. It is necessary to act often and small, carefully. The product can be polished with a drill, or better by hand - with a peeler.

It remains only to clean the finished product from dust, to protonate it, if that is the plan. The wooden growth is sometimes treated with varnish, sometimes with wax, hot oil is also used. And this process is long, the labor costs are significant. But souvel products cost a lot.

Application

Birch bone products are diverse - what the author's imagination cannot create.  The most fashionable jewelry is considered to be: original costume jewelry, which today, in the era of eco-style, boho direction in design, is especially in demand.  Such jewelry will suit those who love natural materials, natural colors - beige, milky, green, sand.

They make very beautiful dishes from birch bone.  Cutting boards can probably be considered the most popular name today. But, of course, knife handles also compete with boards - and this is already a tradition. The material is dense, easy to process, very beautiful, so knife handles will be clearly in demand. Knives have been around for years, even decades. Renovations in the kitchen can change, as can a large part of the dishes, so you need quality and beautiful knives, timeless and changing fashion. And the birch bone handles are the best fit.

Figures of birds and animals also allow you to make a souvel, because the wooden pattern so perfectly visually repeats the plumage of birds, the skin of a snake or the fur of animals. The curves of the material themselves inspire the author, tell the craftsman exactly what to do. A wooden drawing may not be an independent product, but a part of the design of a picture, panel, or other artistic object.

In a word, someone who likes to tinker with wood, knows the value of wooden decor, will have 100 and 1 idea about birch growth called souvelle. And you can be sure that the birch bone product will last for many years.

The maple cap is stabilized

A cap is a growth on a tree trunk, it has a much denser structure with a completely unique cut pattern.

The cap has high strength, the wood of the cap does not burn well, is well processed and polished.

The dimensions of the blanks are approximately 135-45-30 mm.

Bars of stabilized wood are great for creating standard through-mount and countersunk knife handles.
Also, stabilized maple sap is excellent for carving, creating miniatures, jewelry, as well as various pendants, amulets, toys and crafts.
It is convenient to work with a stabilized maple cap for both experienced craftsmen and beginners.
Stabilized wood of any color is straight, even bars of real wood - kapa maple impregnated with a special composition.
The wood stabilizer completely fills all small pores, thanks to which all the air and moisture come out of the wood, turning it into a polymerized bar of stabilized Karelian birch, only with improved properties.

Stabilized wood is many times heavier and much denser. It is not exposed to moisture, does not change its color under sunlight, remaining a much stronger and more reliable material.
All this makes stabilization an ideal material for creating objects that are exposed to all physical and climatic stresses - knife handles, cutters and various tools.

Stabilized maple sap is perfectly sanded, giving a surface as smooth as glass or stone. Without a coating in dry form, the stabilized bars have a faded appearance, but under the finishing compositions their bright deep texture is revealed.

For its unique beauty, the cap is called wooden malachite!

In general, the smaller the pattern and the larger the cap, the more expensive it is.

The value of this unique material is told by a historical fact given in the book "Kapova Skrynka" (author Nadiya Perminova): "... in 1837, up to fifty rubles were paid for an increase in cap of twenty pounds (a little more than 8 kg) ... the same amount was estimated thoroughbred bull at an agricultural exhibition.

Today, on the world market, the price of veneered wood (solid and veneer) is many times higher than the price of any other, including: oak, elm, walnut, mahogany and any exotic species.

The unique combination of material properties, limited stocks and the uniqueness of the cap pattern in each product ultimately determined the universally recognized, high aesthetic value and the corresponding consumer price of products made of this wood, which is used in the decoration of the most luxurious interiors.

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 product 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".
