Powdered steel Crucible CPM® S125V™
CPM® S125V™ is a high-alloy martensitic stainless tool steel manufactured by Crucible Industries (USA). The corrosion resistance of the alloy is comparable to ZDP-189, that is, it is quite high. Steel ZDP-189 contains 20% chromium versus 14% for CPM S125V. The amount of carbon is about the same. It would seem that 125ya should rust more, but in ZDP-189 much more chromium goes into carbides than in S125V, where vanadium also goes into carbides. As a result, the chromium content in the solid solution for both steels is not so different.

Recently, many knife manufacturers have abandoned the CPM S125V, primarily due to the complexity of the finish. Custom craftsman Phil Wilson (Phil Wilson) said that handmade satin S125V takes three times longer than for CPM 10V - one of the most difficult steels (more or less mass-produced).

The steel is made using the technology of amorphous metal alloys, better known among knife makers and hobbyists under the acronym CPM (Crucible Particle Metallurgy). The CPM process makes it possible to produce a very uniform, high quality steel that is characterized by superior stability, uniformity and toughness compared to steels from traditional heat production.

Powdered high speed steel was developed in Sweden in the late 60s of the last century. The powder metallurgy method makes it possible to introduce more alloying elements into the steel without reducing the strength and machinability.

Powder steel, unlike ordinary steel, is fed in molten form through a special nozzle through a stream of liquid nitrogen. Steel quickly hardens into small particles. The result is a powder with a uniform arrangement of carbides (the place of accumulation of carbides is the place where cracks originate). Carbides perform the same function in the composition of steel as cobblestones on the street: they (carbides) are harder than the steel surrounding them, and contribute to its increase in wear resistance.

The resulting powder is sieved and placed in a steel container in which a vacuum is created. Next, the contents of the container are sintered at high temperature and pressure - thus achieving material homogeneity. This process is called hot isostatic pressing. The steel is then pressure treated. The result is a high speed steel with very small carbide particles evenly distributed in the steel substrate. The resulting steel can be rolled in the traditional way, as well as serial grades of steel, resulting in its increased strength.

Differences in the wear resistance of different grades of powder steel are explained by the presence of different carbides in their composition in different proportions and with different distribution uniformity throughout the steel volume. Of two steels having approximately the same hardness, the more wear-resistant will be the one in which there are more carbides or they are harder.

Steel composition:

• C 3.3% - the carbon content in the alloy is 3.3%. Carbon is the most important element in steel, it increases its strength and gives the metal good hardness.
• Cr 14.0% - the chromium content in the alloy is 14.0%. Chromium is a greyish-white lustrous hard metal. Chromium affects the ability of steel to harden, gives the alloy anti-corrosion properties and increases its wear resistance. Contained in stainless steel of any brand.
• Mo 2.5% - the molybdenum content in the alloy is 2.5%. Molybdenum is a silvery white metal. Molybdenum is a hard-melting element, it prevents brittleness and brittleness of the blade, giving it the necessary rigidity, making it sufficiently resistant to high temperatures.
• V 12.0% - the content of vanadium in the alloy is 12.0%. Vanadium is a grayish-white lustrous metal with great hardness. It is responsible for elasticity and enhances the properties of chromium, makes the metal inert to aggressive chemical environments.

It is worth knowing that the walrus tusk, which you would like to sell, must have maximum integrity, then its value will meet your best expectations.
When selling, be guided by 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 make the assessment is very important in this matter: not every advertisement “I will buy a walrus tusk” is actually supported by professionals, so you need to be careful and careful when choosing a buyer.

Walrus tusk products

Hunters for rarities seek to buy a walrus tusk not only in its original form, souvenirs and crafts, the material for which is a walrus tusk, are no less popular and in demand, their cost can also reach a decent amount, especially if these are antiques. The natural appeal of tusks, their particular color and structure, embodied in art objects, create a special atmosphere of luxury in any room. This makes tusk crafts a unique, status gift, relevant at all times, capable of becoming a value, even inherited. Most often there are crafts made by the inhabitants of the peoples of the North, reflecting their life and way of life:

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

• group and single animalistic images (bears, seals, deer);
• sculptures depicting harness dogs;
• images of people engaged in characteristic activities, such as a hunter;
• deity images.

The 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 on average 500 - 800 kg. The length of adult walruses is 2 - 3.5 m.

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

A distinctive feature of these pinnipeds is their huge tusks. Their length can reach 1 m. They help the animal when moving on a slippery surface and for breaking through ice. The tusks are elongated upper fangs pointing down. In males, they are larger and are used for battles with other males during the mating season. Males with the largest tusks dominate the herd.

The muzzle is wide, with hard thick antennae-setae on the upper lip. The eyes are small. The ear holes are hidden under the skin and do not have an exit to the outside. The tail is small. The front flippers are well developed, allowing walruses to move more or less normally on land, unlike many other pinnipeds that can only crawl on land.

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

The Pacific walrus population is the largest both in terms of numbers and size of animals. It lives on the northern coast of Eastern Siberia, on Wrangel Island, in northern Alaska. In winter, herds of walruses move south - to the Bering Sea, to Kamchatka and to the southern coast of Alaska. According to modern estimates, the population is 200 thousand animals.

The Atlantic walrus is about a third smaller than its Pacific relatives. It 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 - 20 thousand individuals.

The Laptev walrus population is the smallest - about 5 thousand individuals. It is isolated from other populations in the Laptev Sea and the Kara Sea.

The state of the population and the relationship with humans
In the 18-19 centuries. commercial fishing for the Atlantic walrus has led to the almost complete extinction of this animal. Currently, hunting for it is prohibited everywhere, but some indigenous peoples of the north are allowed to hunt a small number of walruses, but necessarily for their own consumption, with a ban on the sale of meat, fat or bones of the animal. For European walrus meat dishes do not seem tasty, but cooked walrus tongue is considered a delicacy.

Chukchi, Yupik peoples (Russian Far East) and Inuit (North America) consume walrus meat all winter, flippers are canned and stored until spring, tusks and bones are used to make various tools, amulets and jewelry. 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 in survival as they did 100 years ago, but they still remain in demand for many indigenous peoples, and walrus skin carving and beading is an important art form.

Walrus populations are difficult to determine. The fertility of animals and their mortality are not fully understood. Complicates the calculation and difficult climatic conditions of the habitat of walruses. The Pacific walrus is currently classified as "endangered" by the Endangered Species Act. The Atlantic walrus and the Laptev population are listed in the Red Data Book of Russia and are assigned to the second (decreasing in numbers) and third (rare) groups of rarity, respectively.

The effects of global warming are another area 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 habitual habitats.

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

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