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.

(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)...

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.
