Powdered steel Crucible CPM® S110V™

CPM-S110V is a high-alloy martensitic stainless tool steel produced by Crucible Industries (USA). CPM-S110V contains a fairly large amount of vanadium and niobium, which increase the strength, wear resistance and corrosion resistance of steel, and the addition of cobalt increases the secondary hardness. Due to this composition, CPM-S110V steel has better corrosion resistance than 440C or CPM-S90V steel.

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. It is used for the production of parts and tools with increased wear resistance and corrosion resistance.

Despite its hardness, the steel has excellent edge retention, but is considered by many to be not aggressive enough. Sharpening blades made of CPM S110V steel will be more difficult than blades made of 440C (or D2 ) steel and comparable to sharpening blades made of CPM S90V steel. Premium steel CPM S110V is used in the production of the most expensive, author's and, extremely rarely, serial knives.

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 2.8% - the carbon content in the alloy is 2.8%. Carbon is the most important element in steel, it increases its strength and gives the metal good hardness.

Cr 15.25% - the chromium content in the alloy is 15.25%. 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 2.25% - the molybdenum content in the alloy is 2.25%. 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 9.0% - the content of vanadium in the alloy is 9.0%. 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.

Nb 3.0% - the content of niobium in the alloy is 3.0%. Niobium is a steel gray metal. It is a refractory metal with high resistance to corrosion. It acts as an alloy steel, increasing its properties several times. The steel becomes harder, more ductile and wear-resistant, able to retain sharpening longer than most chromium-containing alloys,

Co 2.5% - the cobalt content in the alloy is 2.5%. Cobalt is a silvery-white, slightly yellowish metal with a pinkish or bluish tint. Increases heat resistance, improves mechanical properties. From alloys using cobalt, a processing tool is created: drills, cutters, etc.

It is worth remembering that when using a knife 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.
