Steel N690: composition, interpretation and application

Features of steel N690

Martensitic alloy steel N690 is produced by the Vohleg-Uddeholm Gmbh&C corporation, which has its enterprises in Austria, Germany, South and North America. Another name for 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 serial production of long-range 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. 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, parts of bearings and relevant 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 aggressive media;
■ 1.5% cobalt (C) 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 STEELS FOR KNIVES
The use of Austrian N690 steel allows for 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 prone 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 3-5 mm thick, 20-50 mm wide and 250 to 1000 mm long, 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, which allows you to accurately determine the amount of necessary material and reduces the amount of waste.
Strips are sold individually. The price depends on the geometric dimensions of the product, thicknesses and types of preliminary factory processing. For the products of the metalworking industry, we supply a sheet 2-8 mm thick, the size stated in the contract. If necessary, you can order any analogue of steels of type N690. Sheet metal is sold by weight.

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".

Description of the Zirikot tree breed

Zirikot wood is one of the most valuable and expensive species used in knifemaking. Usually, this wood is used for inlaying small valuable exclusive products such as watch bezels, brooch rings, etc. This is due to the fact that, in addition to its beautiful appearance, this wood keeps its shape well under changes in external conditions (changes in temperature, humidity, etc.). Of course, Zirikote is great for making knife handles, but not many craftsmen can get enough material for a whole handle, usually using Zirikote as small elements and in very rare cases making the main part of the handle from this beautiful wood.
The botanical name of Zirikote is Cordia dodecandra. This plant belongs to the Cordiaceae family of the Cordia genus. The halo of tree growth is quite wide - from the tropical and subtropical forests of Central America, the islands of the Caribbean Sea, Mexico and Cuba to Guatemala, Honduras, and Belize. Some trees of the Zirikot species grow even in Africa. other names of this tree: Siricote, Siricote, Zircote, Ziracote, Cordia twelve thousand, Trees of Yucatan, etc.
The main representatives of the genus Cordia have the form of shrubs or low-growing trees, but the evergreen tree Zirikote usually grows to a height of 10 - 20 meters, rarely reaching 30 meters. The diameter of the trunk is 0.6 - 1 meter.
Ziricote sapwood of golden-brown tones. The color of the kernel varies from red-brown to almost chocolate-black shades, sometimes with a slight greenish or purple tint. Craftsmen working with this wood often combine sapwood and heartwood for a more vivid aesthetic effect.
The high decorative value of wood is given by veins found in the structure of the core. The older the tree, the darker the pattern structure. They can be of various configurations, depict the most cunning patterns.
The texture of ziricote is fine-porous, straight-fibered, sometimes with a slight interweaving of fibers. The sawing angle determines the shape of the pattern of the lumber surface. Polishing allows you to achieve a good shine and gloss.
Zirikote wood has a high density - at 12% humidity, it is 940 kg/m2, so Zirikote is considered a very heavy breed. The modulus of elasticity is equal to 10.93 hPa. Zirikote wood is characterized by a high compressive strength of 63.9 MPa and a tensile strength of 113.1 MPa and a high hardness coefficient.
Zirikot wood is quite easy to process even with hand tools. Ziricot painting requires additional surface treatment due to the presence of a large amount of essential oils in the wood. But despite this, Zirikot wood glues well. Grinding allows you to achieve a perfectly even surface, it is perfectly finished with carnauba wax, shellac, varnish. Holds fasteners well. Unlike most exotic wood species, Ziricote is not a pronounced allergen, however, when mechanically processed, it can emit a rather unpleasant specific smell.

Walrus tusk for a handmade knife handle

How much is a walrus tusk worth today?

What is the real price for a walrus tusk, the cost of which is often unclear to the average person? How not to get into trouble, responding to ads with the headlines "buy a walrus tusk" or "buy a walrus tusk", how to find out how much a walrus tusk really costs? In order to get reliable answers to these questions, it is worth studying the modern demand for such a rare item as a walrus tusk, the price of which is significantly determined by size, as well as other factors. Taking into account these recommendations, you can count on the most favorable offer that can be given by those who want to buy a walrus tusk.

• It is worth knowing that the walrus tusk that you would like to sell must have maximum integrity, then its value will meet your best expectations.
• When selling, focus on the current exchange rate, which significantly affects how much a walrus tusk will cost, its price is formed taking into account exchange rate fluctuations.
• The competence of the experts who evaluate is very important in this matter: not every ad "I will buy a walrus tusk" is really backed by professionals, so you need to be careful and careful when choosing a buyer.

Products from walrus tusks

Rare hunters seek to buy a walrus tusk not only in its original form, souvenirs and products made from walrus tusk are no less popular and sought-after, the cost of which can also reach a decent amount, especially if they are antique items. The natural appeal of tusks, the peculiarities of their color and structure, embodied in works of art, create a special atmosphere of luxury in any room. This makes products made of tusks a unique, status gift, relevant at all times, capable of becoming a value that can even be passed down as an inheritance. The most common products made by the peoples of the North that reflect their life and lifestyle are:

• knives with walrus tusk handles are very expensive and popular among collectors and hunters

• group and single animalistic images (bears, seals, deer);
• sculptures depicting a team of dogs;
• images of people in typical occupations, such as hunter;
• images of deities.

A walrus is  a very large animal with thick, wrinkled skin. Males have large skin growths on the neck and shoulders. The larger these growths, the more attractive they seem to females. The thickness of the skin reaches 10 cm, and subcutaneous fat - 15 cm. Males are much larger than females - the weight of some individuals reaches 2 tons, but usually does not exceed 800 - 1500 kg. Females weigh 500-800 kg on average. The length of adult walruses is 2-3.5 m.

Young walruses have dark brown skin with yellowish hairs. Adult animals "go bald" over time, and their skin acquires a lighter shade. Old individuals become almost pink by the end of their lives.

A distinctive feature of these pinnipeds is huge tusks. Their length can reach 1 m. They help the animal when moving on a slippery surface and for breaking ice. Tusks are elongated upper canines that point downward. In males, they are larger and are used for battles with other males during the mating season. Males with the largest tusks occupy a dominant position in the herd.

The muzzle is wide, with thick stiff antennae-bristles on the upper lip. The eyes are small. The ear holes are hidden under the skin and there is no way out. The tail is small. The front flippers are well developed, allowing walruses to move more or less normally on land, unlike many other pinnipeds, which can only crawl on land.

There are three populations of walruses with slight external differences - the Pacific, Atlantic and Laptev Sea populations.

The Pacific population of walruses is the largest both in terms of number and size of animals. She lives on the northern coast of Eastern Siberia, on Wrangel Island, in northern Alaska. In winter, herds of walruses move south to the Bereng Sea, to Kamchatka and to the southern coast of Alaska. According to estimates, the population is 200,000 animals.

The Atlantic walrus is about a third smaller than its Pacific relatives. Lives in the north of Canada, Greenland and in the western region of the Russian Arctic. It was almost completely exterminated by man as a result of uncontrolled fishing. Estimated population size - 15,000 - 20,000 individuals.

The Laptiv walrus population is the smallest — about 5,000 individuals. It is isolated from other populations in the Laptev Sea and the Kara Sea.

The state of the population and the attitude towards people
In the 18th and 19th centuries. commercial fishing of the Atlantic walrus led to the almost complete disappearance of this animal. Currently, its hunting is prohibited everywhere, but some indigenous peoples of the north are allowed to harvest a small number of walruses, but necessarily for their own consumption, with a ban on selling the meat, fat or bones of the animal. For a European, walrus meat dishes do not seem tasty, but cooked walrus tongue is considered a delicacy.

Chukchi,  Yupik peoples (Far East of Russia) and Inuit (North America) consume walrus meat all winter, fins are preserved and stored until spring, tusks and bones are used to make various tools, charms and ornaments. Waterproof thick skin - for finishing houses and boats. Modern cheap building materials are available in the far north, and walruses no longer play as important a role for survival as they did 100 years ago, but are still in demand for many indigenous peoples, and walrus skin carving and beading is an important art form.

The number of walrus populations is difficult to determine. The fecundity of animals and their mortality was not fully understood. Complicating the calculation are the complex climatic conditions of the walrus environment. The Pacific walrus is currently classified as "threatened" by the Endangered Species Act. The Atlantic walrus and the Laptev population are listed in the Red Book and are assigned to the second (decreasing numbers) and third (rare) groups of rarity, respectively.

The consequences of global warming are another subject of concern for zoologists. The volume and thickness of pack ice (at least 3 meters thick and older than 2 years) is constantly decreasing, which affects the birth rate of animals and the disappearance of their usual habitats.

According to various estimates, the number of all walrus populations is 200-250 thousand.

Interesting facts about walruses

• During the last ice age, walruses were distributed up to 37 degrees north latitude. This is evidenced by the remains found, dated to the age of 28,000 years. near San Francisco in the USA. At the same latitude is the northern border of the African continent, Greece, Japan, and Turkey.
• Despite their large size, walruses are sometimes attacked by killer whales.
• With a strong current, walruses cling to the edge of the ice with their tusks, keeping themselves under water. They also help animals to climb high ice. This use of tusks gave walruses the generic name Odobenus rosmarus, which translates from Greek as "one who walks on teeth."
• The stomach of the walrus is so large that the peoples of the north made waterproof capes from it.
• In cold water, the animal's blood vessels are greatly reduced, which makes the animal's skin almost white.

The buffalo is the king of the desert and jungle

Every description of a buffalo - African or Asian - should begin with the words "huge, formidable wild bull". But the classification includes several species, and they differ not only in appearance. Looking at the photos of even-toed ungulates, it seems that it is better not to approach them even a step. However, many peoples have not only successfully domesticated some types of bulls, but also get along well with wild ones.

African buffalo

The black king of the desert, able to resist predatory cats and in most cases defeats them. The description of the buffalo inspires justified fears: adults grow up to 1.8 m in height and 3.5 in length. The weight of an adult male can reach 1000 kg. The head is at the level below the withers, which is why the animals always have such a formidable appearance. In battles, buffaloes are helped by their main weapon - helmet-shaped horns.

WARNING! The number of even-toed ungulates has significantly decreased with the arrival of man on the previously wild lands. The African species is now protected by humans to avoid eventual extinction. Hunting is allowed strictly during the season and during a limited time.

1. Feeding. Animals graze together, herds are not dispersed too widely. They eat grass and other greens, but always stay close to water bodies. Pasture is a signal to people about the proximity of water.
2. Reproduction. In the spring, fierce battles take place between males - this is the mating season. Young people and too old individuals very rarely manage to win back their right, so merciless are their opponents. Offspring appear after 11 months. At 2 months, calves begin to feed on grass.
   
3. Lifetime. Lives for about 20 years. The herd always protects its own, so predators rarely succeed in capturing a bull. Hoofed animals do not attack each other, except during the mating season.

Asian buffalo

The Indian counterpart of the king of the desert is not inferior to him in size. 2 m in height and 3 in length, two-meter horns bent upwards - Asian ones also strike fear into other representatives of the fauna. However, man took the risk of taming these even-toed ungulates.

WARNING! The species is on the brink of extinction - man is settling more and more land, gradually displacing bulls. Hunting is allowed only in Australia, in the territories of Southeast Asia and India, the buffalo is listed in the Red Book, and the Tamarau variety is considered almost lost - you can see this bull in a photo or in a protected area.

1. Feeding. The herd spends all its time in coastal areas. Bulls eat not only ordinary grass, they also eat aquatic vegetation. The hot climate forces the animals to literally spend the whole day in the water, they eat cool food in the morning or evening.
2. Reproduction. Indian species do not follow a clear order of mating periods. The calf appears after 11 months and feeds on milk until 9 months, while nibbling grass from 2 months. age
3. Lifetime. Just like other species, Indian buffalo live up to 20 years. Defeating the Asian bull is not easy, because the herd uses cunning waiting tactics and catches the enemy on its trail.

Interesting Facts

• The description of buffaloes is not limited to frighteningly huge individuals, there are also mini-bulls. Asian ungulates are divided into several dwarf species: antelope-like tamarau - 300 kg, mountain and plain anoa - 150 kg.
• Wild buffaloes lose their numbers not only due to extermination. Domesticated bulls mate with wild females and "spoil" the pure blood of the latter.
• The only enemy against which a giant buffalo is helpless, capable of tearing a tiger apart, is an insect. Ticks and other pests burrow into the wool of bulls and even lay eggs in it. Cope with this scourge, even-toed ungulates are helped by birds - they fearlessly sit right on the giants' backs and peck out insects.
• Some nations consume buffalo milk and meat. Mozzarella cheese is based on the fatty milk of buffaloes.

• Dwarf bulls live longer than their tall brothers. The average life expectancy reaches 30 years.
• A wounded buffalo fights to the end and mostly wins.

The wild bull is rightfully considered the king of wild African and Asian lands. The description of the buffalo boils down to the readiness to fight to the last breath and always protect the members of the herd at the cost of his life.
