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.

The percentage of carbides in the composition of steel CPM-S90V, compared with some other equally popular steels

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)...

 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.
