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.

Similar analogs:

(CPM™) is a patented technology from Crucible invented in 1970. Without going into production details, a short list of the advantages of the CPM process: small grain size, improved toughness, wear resistance, grindability, expected response to heat treatment, etc.

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 (Carbon Fiber)

Handle materials of modern knives
With wooden, metal, cork, birch bark handles, as well as handles made of horn, leather or bone, everything is more or less clear. Their merits and demerits are known. But what is a handle made of G-10, GRN, Kraton, Zytel, Micarta and others? Let's figure it out. In this review, we will list modern synthetic materials that are widely used by leading knife companies in the production of blade handles.

The common thing that unites modern handles is their high moisture resistance, wear resistance, strength, reliable grip and tactile sensations (it's just nice to hold in your hand). Winning in consumer and mechanical properties, they can imitate natural materials.

Carbon (Carbon Fiber) - a laminate consisting of finely woven carbon fiber impregnated with epoxy resin and polymerized under pressure. Carbon or carbon fiber is a heavy-duty "space" material that allows you to significantly reduce the weight of the knife by reducing the metal elements of the knife (handle frame, liners). After polymerization, Carbon takes on an unusual and recognizable appearance. Used only in the manufacture of folding knife handles. The most durable and most expensive material for handles listed above.

Micarta is a laminate consisting of a porous natural material (cotton fabric, linen, paper) impregnated with various polymeric epoxy and phenol-containing resins and polymerized under pressure. In the industry of the Russian Federation, this material is known under the names textolite and getinaks. Micarta can imitate expensive wood, ivory and, by adding various dyes, create endless color variations of handles from it. Micarta can withstand heavy loads, while being less tear resistant than G-10 and Carbon Fiber.

G-10 is a laminate consisting of fiberglass impregnated with epoxy resin and polymerized under pressure. The material is stronger than Micarta. It is also possible to give any color scheme, but in mass production it is more common in black. Can be processed from specular to textured state. Used in the manufacture of folding knife handles.

FRN or GFN is a glass fiber reinforced nylon polymer, that is, a thermoplastic. This is an inexpensive material used in the mass production of handles. It is often found in leading knife manufacturers (SOG, Spyderco, CRKT, etc.). Knife handles made from FRN or GFN are very durable. These materials are more flexible and less hard than G-10, but still have excellent impact resistance (virtually no puncture).

Zytel is a thermoplastic based on nylon polymers reinforced with ground glass fibers. It features high strength, rigidity and wear resistance. Zytel is immune to external influences, easily molded into any shape. Somewhat slippery, but with proper processing (texturing) of the handle, this drawback disappears, providing excellent grip with the palm.

Grivory is an analogue of Zytel thermoplastic. More resistant to impact loads and less susceptible to high temperatures.

Kraton (Kraton) and Santoprene - a mixture of elastomers with the addition of special additives, a product of chemical synthesis, a rubber substitute. Compared with rubber, it has higher heat resistance, strength and wear resistance. Kraton handles are characterized by the absence of any slip in the clamped hand under any conditions of using the knife. In this case, the knife seems to "stick" to the palm. Used in fixed blade knives.

Polyamide and other thermoplastics, the oldest material used in the manufacture of knife handles, is by far the most wear resistant. Using the injection molding process, polyamide can be molded into the most intricate shapes.

Polypropylene (Polypropylene) is an inexpensive, hard and durable plastic. Handles made of polypropylene are characterized by high resistance to mechanical damage, cracking and high temperatures.
