Steel CPM S90V. Composition and properties.
Steel grade CPM S90V - stainless tool powder steel made in the USA. First introduced in 1999 by Crucible Industries. Good, fairly strong and wear-resistant steel with a hardness of 56-59 HRC. The content of carbides is about 22% (see information below). The basis for it was 420 steel with the addition of a large amount of vanadium and an increase in carbon levels. There is conflicting information about the cutting properties of CPM S90V - someone (probably sellers) praises, and someone says that with such hardness you can look at simpler steels. I will not argue here - you can always look, but CPM S90V offers a significant improvement in wear resistance compared to the simpler 440C and D2, with corrosion resistance equal to or better than 440C. The high vanadium content of S90V promotes the formation of harder vanadium carbides than chromium carbides, leaving more free chromium for corrosion resistance. When sharpening the CPM S90V, it makes sense to give preference to diamonds, CBN or silicon carbide stones. When using natural whetstones in the finish, I would look at the sides of not too hard stones.

PROPERTIES OF STEEL ELEMENTS:

  • Carbon (C, Carbon): improves edge retention and toughness; increases hardness and wear resistance; reduces plasticity; in large values reduces corrosion resistance.
  • Chromium (Cr, Chromium): increases hardness, tensile strength and density; increase resistance to corrosion (>11% makes the alloy stainless).
  • Manganese (Mn, Manganese): increases hardenability, wear resistance and toughness; used as a deoxidizer and degasser to remove oxygen during metal melting; in large% increases hardness and brittleness.
  • Molybdenum (Mo, Molybdenum): increases hardness, strength, hardenability and density; improves machinability and corrosion resistance.
  • Nickel (Ni, Nickel): adds toughness; improves corrosion resistance; reduces hardness.
  • Phosphorus (P, Phosphorus): is considered a harmful impurity. Dissolves in ferrite, due to this, strength increases, but ductility and toughness decrease with an increase in the steel's tendency to brittleness. In low-alloy steels with about 0.1% carbon, phosphorus increases strength and resistance to atmospheric corrosion. It is considered a harmful impurity.
  • Silicon (Si, Silicon): increases strength; used as a deoxidizer and degasser to remove oxygen during metal smelting.
  • Sulfur (S, Sulfur): usually considered a harmful impurity affecting ductility, toughness, weldability, corrosion properties, steel surface quality, etc. The harmful effect of sulfur reduces the presence of manganese in steel. The sulfur content in quality steels does not exceed 0.02-0.03%.
  • Vanadium (V, Vanadium): increases strength, wear resistance, increases density and viscosity; increases corrosion resistance by increasing the oxide film; vanadium carbide inclusions are very hard.
  • Tungsten (W, Tungsten): adds strength, toughness and improves hardenability; retains hardness at high temperatures.
  • Cobalt (Co, Cobalt): increases strength and hardness, allows hardening at higher temperatures; enhances the effects of other elements in complex steels.
  • Niobium (Nb, Niobium): limits the growth of carbides; limits workability; creates the hardest carbides.
  • Nitrogen (N, Nitrogen): used in place of carbon in the steel matrix (nitrogen atoms function similarly to carbon atoms but have advantages in corrosion resistance)...

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.
