Steel DI90-MP. Composition and properties.
Steel grade DI90-MP (17X5V3MF5S2-MP) - tool alloyed powder steel from the Ukrainian enterprise Dneprospetsstal (Zaporozhye). If we give a decoding of the name itself, then D is the manufacturer, I is research, MP is powder metallurgy. The main purpose of Art. DI90-MP: production of dies and punches for stamping equipment, heavily loaded elements of cold-forming dies operating in conditions of increased wear. The hardness of DI90-MP is 61-62 HRC, the secondary hardness is 63-65HRC. Requires attention in heat treatment. The microstructure is homogeneous, with highly hard chromium and vanadium carbides. Steel is considered a very good steel for the manufacture of designer knives and blades: good wear resistance and impact strength (decreases after secondary hardening), keeps sharpening very well. The main disadvantage is low corrosion resistance - a blade made of DI90-MP quickly rusts, does not like dampness and moisture.
Judging by the official website of the manufacturer, at the moment this steel is not manufactured. Perhaps that is why, small batches of it periodically appearing on sale have a very high price.

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)...

Stonewash
Blade Finishing - Popular Varieties
Surely, it is not a secret for experienced knife lovers what the various markings in the description of blades mean, such as: “stonewash” or “satin”. Of course, we are talking about the finishing of the blade, which all novice knife owners should know about. The steel of the knife blades is subjected to a certain processing in production. This is done to prevent corrosion, to improve the appearance, to give the knife certain properties. Consider the most popular types of processing knife steels.
Mirror polish
Simple polishing of the blade is one of the most traditional methods of processing. This method has been used since time immemorial, where the entire blade is simply polished by hand. This type of processing also has a more advanced version - mirror polishing, where the blade is polished to such an extent that the steel becomes like a mirror. This is one of the most beautiful and expensive blade finishes. At present, such polishing is very, very rare on serial knives, even on the most expensive ones. It's all about the need for long and meticulous processing by hand, which is why it is impossible to produce knives in large batches in this way, in series. Therefore, the "mirror" has now taken root only on custom knives and limited knives.
Perhaps the main disadvantage of this type of finishing is poor resistance to scratches and other damage. For this reason, mirror-polished knives are souvenir and collector's items, not intended for any kind of work.
Satin
Satin is one of the most common types of blade finishing. This is typically an uncoated blade that has been machine-polished (or, more rarely, hand-polished) to give the steel a greater luster. After processing on steel, a characteristic shading is obtained. The most common types of satin are longitudinal and transverse, which differ in the direction of grinding. Pronounced strokes are often referred to as "rough satin". You can do it yourself using simple abrasives such as sandpaper. Unlike polishing, scuffs and scratches on the blade will not be as noticeable.
Satin-finishing is one of the cheapest and most popular finishes, and is most often used in mass production of inexpensive knives, but this treatment is not recommended for high-carbon steels due to their poor resistance to corrosion.
Stonewash
Processing, also known as "tumbling". It is well suited for work knives that will be used frequently and intensively, because scratches and minor damage are almost invisible on such a surface. The processing technology is simple - the blades are placed in a container with pebbles, and "washed" at high speeds. Stones grind steel, and a unique pattern is formed on it. Also, fingerprints are almost imperceptible on blades with stonewash. You can also do the tumbling on the blade yourself using pebbles, a plastic can and a washing machine (or manually), although the quality of processing will be inferior to the factory one.
One of the varieties of stonewash is blackwash , which differs from the standard processing in a darker texture. To achieve this effect, the blade is pre-etched.
Bead Blast
From those who are a little versed in the types of finishing of knives, you can hear that bid-blast is stonewash, but in fact they are different types of coatings. In this case, the surface of the steel is bombarded with sand or plastic particles. The result of this treatment is a smooth matte surface. The knife does not shine and does not glare. Such a coating also hides scratches well (but stonewash still copes better with this). The coating has a rougher structure than satin, and is more susceptible to corrosion.
Various coatings
In addition to processing, a protective coating can also be applied to the knife blades. This is done both for aesthetics, as well as to protect against corrosion of carbon steels, or so that the blade does not glare. There are quite a few types of coatings, and one of the best (and expensive) is vacuum treatment of steel with titanium nitride particles. In cheap coated knives, it is usually unstable, quickly torn off during operation, and such a knife quickly loses its presentation.
The most famous types of coatings:
- Powder.
- Titanium nitride.
- DLC stands for Diamond Like Carbon and is the most durable and damage resistant. Very costly.
WHAT ARE MICARTA AND G10 AND HOW THESE COMPOSITE MATERIALS DIFFER FROM EACH OTHER
For decades, Micarta and G10 composite materials have been undisputed leaders in the knife industry, in particular for the production of handles of various complexity. The materials are distinguished by their availability, ease of production and processing, as well as high strength, wear resistance and unpretentiousness in maintenance. Both materials are composite, based on polymer resin, which is supplemented with layers of different types of captive fabric.
Micarta-G10-Composite-materials-photo-2
Micarta material is an electrical insulating material consisting of a polymer film (based on cresolaldehyde, phenolaldehyde, xylenolaldehyde resin, or resin from a mixture of phenolic raw materials). It is glued with the help of various electrically insulating papers, fabric (mainly linen of natural or artificial origin), or other materials of a similar structure, there are also options made of fiberglass and carbon fiber. The color of the material depends on the resin and fabric base used for gluing. Micarta is a relatively soft material and requires careful manual processing. Therefore, it is used in the production of handles for more expensive knives.
Micart is registered as a trademark of the American company Industrial Laminates / Norplex, Inc. (Norplex-Micarta). Its domestic analogue can be considered a material called "Getinax", which is mainly used as a basis for printed circuit boards. The material also has a sheet pressed structure, which consists of a paper base with the addition of phenolaldehyde or epoxy resin impregnation.
Linen-based micarta has a more attractive optical effect when sanding the fibers. After grinding, the surface can be polished or sandblasted. In the first option, the surface of the material will be smooth, silky, warm and pleasant to the touch. And in the second, the material becomes rough and has a matte shade, besides, it is securely held in the hand and does not slip.
Main characteristics of Micarta:
increased water resistance;
excellent resistance to temperature changes;
strength to mechanical processing;
dense structure that does not absorb odors;
the micro-relief of the material does not slip in the hand even when the surface is wet;
tight fit to the blade, which leaves no gaps at all and prevents food residues and harmful microorganisms from accumulating.
G10 material is a light, hard and fairly stiff composite material with a textured surface, which is mainly used in the manufacture of handles of both folding pocket knives and knives with a fixed blade. This material is created by placing several layers of fiberglass, thoroughly impregnated with epoxy resin, in a special vacuum press, where, under the influence of compression and heat, the resin finally hardens, preserving the structure of the fiberglass.
The G10 material is characterized by good impact resistance, wear resistance, moisture resistance, as well as ease of processing and maintenance. The material can be painted in different colors, including in layers. The surface of G10 can also be polished to a glossy state, or have a rough anti-slip structure, under the influence of a grinding machine or sandblasting.
Key features of the G10:
high stability of basic properties during temperature fluctuations;
withstands high shock loads, compressive and tensile loads;
high overall hydrophobicity and resistance to chemicals;
weighs relatively little, in relation to the overall strength and density;
low electrical conductivity;
can take different forms.
Composite materials G10 and Micarta have almost the same composition and external similarity. At the same time, the G10 material has higher fire resistance, although it is not a non-flammable material, it has higher compressive, bending, impact and tear strength, and it is also simpler and more economical to manufacture. At the same time, G10 is inferior in terms of "stickiness" in wet conditions, and also, tactilely, it feels less "natural".
