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.

CARBON - KNIFE HANDLES FROM THIS PREMIUM MATERIAL


One of the most prestigious and expensive materials for knife handles, in addition to titanium and expensive woods, is a type of carbon fiber, the so-called "carbon". The material is valued for its exceptional lightness, strength and aesthetic beauty.




Carbon (from the English carbon - carbon) is a polymer material with a composite composition, made from interlaced carbon fiber filaments (carbon fibers). These threads are made using epoxy resins. Average material density from 1450 kg/m³ to 2000 kg/m³. The main difference between carbon fiber and other polymers used in the manufacture of knives is its very low weight. It is the weight combined with exceptional strength that gives carbon an advantage over other handle materials: G10 polymer, Micarta, FRN plastic, etc. At the same time, carbon fiber surpasses structural steels in terms of specific strength characteristics. The main qualities of carbon are: high tensile strength, resistance to high temperatures, aggressive environments, slight expansion when heated, high electrical conductivity. Another important feature of carbon fiber is its natural black color obtained during production, which gives it a noble and elite appearance.

 

The basis of the material is carbon fiber threads, with an average thickness of 0.005-0.010 mm in diameter. Carbon fibers are made through a complex heat treatment process. The main fiber (polyacryl, viscose) is initially oxidized in air at 250°C for 24 hours. As a result of oxidation, ladder structures are formed (polymers whose macromolecules are crosslinked in pairs by regular chemical bonds). Then carbonization takes place (the process of enriching the filaments with carbon), which takes place when the fiber is heated in nitrogen or argon at temperatures from 800 to 1500 °C. As a result of carbonization, graphite-like structures (allotropic modifications of carbon) are formed. The heat treatment process ends with graphitization (the formation of graphite in materials in which carbon is contained in a dissolved state or in the form of carbides), it takes place at a temperature of 1600-3000 ° C, in an inert environment. As a result of graphitization, the amount of carbon in the fiber is brought to 99%. In addition to conventional organic fibers, special fibers from phenolic resins, lignin, coal and petroleum pitches can be used to produce carbon filaments.

 

Carbon fabrics, in turn, are obtained by weaving threads or ribbons. In the production of these threads, carbon roving is taken as the basis - a bundle of thin continuous carbon fiber filaments with a thickness of 3 microns, formed by carbon atoms. After interlacing, they form a carbon fiber frame. The amount of carbon fiber in a thread is estimated by the number "K" - the number of thousands of elementary carbon fibers. The thinnest and most expensive carbon fiber is 1K, the most common carbon fiber is 3K, there are also carbon fiber threads with K \u003d 6, 12, 24, 48. Fabric made from threads can have a variety of weaving patterns (herringbone, matting, twill weaving, etc.). To give even greater strength to the fabric, carbon threads are laid in layers, each time changing the angle of the direction of weaving. The layers are held together with epoxy resins. This structure of carbon makes it possible to reinforce the fiber with additional elements that strengthen its structure and give it different colors and surface textures. These materials can be various threads, sequins, polymeric materials of different colors.


 

The main methods for manufacturing carbon plates are:

Pressing, in which the fabric is lined in a form, previously lubricated with a so-called release agent, designed to reduce the adhesion of surfaces to each other. They can be soap, wax, etc. The fabric is then impregnated with resin and the excess is removed under vacuum (vacuum molding) or under pressure. After polymerization of the resin, the product takes on a finished look.

Vacuum infusion allows you to create a laminated bag by superimposing layers of tissue on top of each other and vacuum is applied under the layers. Then, a binder is fed through the valve and, under the action of vacuum, it fills the voids and impregnates the carbon fabric.

Vacuum forming is the bonding of layers at high temperatures and then exposure to vacuum to form the volume of the product. This method is one of the cheapest.

Winding method, which consists in winding the impregnated roving on a pre-prepared form. After winding the required number of layers, the mold with the wound fabric is placed in a heating oven and polymerized.

The SMC/BMC method consists of placing the fabric in a mold heated to operating temperature. The mold closes, as a result of which, under pressure, the material spreads into the mold cavity and hardens. At the end of the cycle, the product is removed from the molds us, and its final machining and coloring is carried out.

 

 
 

Carbon fiber is used in various fields. In particular, in aircraft and rocket building, in the production of body parts for cars and motorcycles, household appliances and high-tech research instruments. And for about 20 years, carbon fiber has been widely used in the manufacture of knife handles in the middle and premium segments. At the same time, on folding knives, carbon can be both in the form of overlays on steel liners, and in the form of the only material of the handle, fixed with screws through the bonks.

The carbon used for the manufacture of knives, in addition to its main strength characteristics, must also have a fairly attractive appearance. It is this factor that increases its cost, complicating the production technology and requiring the highest quality raw materials. For sizing the layers, the most expensive and high-quality resins are used, and more expensive equipment, in particular chemical reactors (autoclaves). In addition, the carbon fiber is sandblasted to improve hand grip, which also increases production costs. It must also be remembered that working with carbon requires mandatory respiratory protection and special rooms with good ventilation, and this also leads to an increase in price.

The color palette and texture of carbon used on knives can be varied. Among the varieties of carbon are used:

Mosaic carbon, which can be both plain and multi-colored. Such carbon is used for radius spacers on knives with complex multi-section handles. Several dyeing technologies can be used in this carbon.


 

Marble carbon is a chaotic interlacing of carbon fibers, each of which reflects light differently, which makes it possible to shine from different viewing angles.

Carbon Lightning Strike ("lightning strike") with a copper thread in the form of a grid woven into carbon fabric throughout its volume. Outwardly similar to that used in the fuselages of American aircraft to protect against lightning strikes. This is a thin carbon, 3.2 mm thick twill weave. It has a deep and bright pattern.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Like any expensive, and at the same time difficult to manufacture material, carbon has a number of disadvantages. In the production of carbon fiber plastics, it is necessary to strictly adhere to the technological parameters, in violation of which the strength properties of products are sharply reduced. To control the quality of products, ultrasonic flaw detection, X-ray and optical holography, as well as acoustic testing can be used. Without them, the manufacturer works “by touch” and may not notice hidden defects. Another serious drawback of CFRPs is their low impact resistance. It is also necessary to remember that carbon fades over time and can significantly lose its main advantage - an attractive appearance. However, despite these shortcomings, carbon is rightfully the premium material for the best knives.
