Steel K390 for knives: advantages and disadvantages of the alloy

K390 steel from the Austrian company Bohler is considered one of the best for making knives and other cutting tools. This is a tool powder steel designed for the production of stamping tools by cold deformation. It is mainly used for the manufacture of folding and hunting (butchering) knives.

For the production of kitchen knives, as a rule, it is not used because of the high cost. Knives of the highest price category are produced from this alloy. But, like other types of steel alloys, the material has its own advantages and disadvantages.

K390 Alloy Features
Steel grade K390 is characterized by increased hardness, strength and wear resistance. It is a high speed steel with high toughness and resistance to mechanical wear. The special chemical composition provides high hardness of the material, due to which the cutting edge of the blade retains its sharpness for the longest possible time even during hard use.

At the moment, the brand is considered one of the best tool steels on the market for the production of cutting tools. During production, a homogeneous carbide structure is formed, which guarantees maximum hardness and wear resistance.

It has the following chemical composition:

Carbon (C) - 2.5%. Provides hardness, wear resistance and toughness. Due to the high carbon content, the edge retains its sharpness for a long time.
Chromium (Cr) - 4%. Increases density and tensile strength. Provides protection against corrosion, but in this case it is insignificant, since the chromium content is low. Slightly increases hardness.
Molybdenum (Mo) - 4%. Increases strength, hardness and hardenability. Helps protect against corrosion.
Silicon (Si) - 0.55%. Deoxidizes steel and increases strength.
Vanadium (V) - 9%. Improves toughness and strength. Increases resistance to abrasion and rust formation.
Tungsten (W) - 1%. Increases toughness, strength and hardenability. Under the influence of elevated temperatures does not change the hardness.
Cobalt (Co) - 2%. Increases hardness and strength. Allows hardening at elevated temperatures. Enhances the positive properties of other elements.
The HRC (Hardness value on the Rockwell scale) of this alloy varies in the range of 62-66 units. This is one of the best indicators in the steel market for the production of cutting tools. Due to this hardness, the cutting edge retains its hardness for the longest possible time. At the same time, it is quite difficult to sharpen such a hard alloy with household tools.

The material is relatively expensive, so premium segment knives are usually produced from it. At the moment, steel provides the highest possible resistance of the cutting edge to abrasive wear. At the same time, high chip resistance and good impact strength are maintained.

Benefits of K390 steel
The main advantages of the Bohler K390 alloy include:

Increased cutting edge resistance to abrasive and other mechanical wear. The closest analogue in this characteristic is the CPM 10V brand, which was previously considered the standard, but was inferior to K390 in other parameters.
Increased impact strength due to the presence of a sufficient amount of molybdenum, tungsten and cobalt in the composition. According to this characteristic, the alloy is 1.5 times superior to CPM 10V.
Good pliability to grinding and polishing. This allows you to remove deep risks and other stress concentrators from the surface. The blade and cutting edge can be given an almost mirror-like sheen.
Increased compressive strength. This allows you to produce all kinds of dies, dies, band knives and other parts.
Chip resistant. This ensures reliability and long service life of finished products.
Structure homogeneity. Thanks to this, the characteristics are stable over the entire area of ​​the blade.
High hardness - 62-66 HRC. Even with intensive and hard use, the blade remains sharp for a long time.
Resistant to overheating during heat treatment. Steel withstands long-term heat treatment without deterioration of properties, which guarantees high-quality hardening and annealing.
The possibility of manufacturing blades by forging. This allows craftsmen to produce unique collectible items.
Possibility of additional performance enhancement in the process of manufacturing finished products. For example, some manufacturers implement additional heat treatment using multiple thermal cycling and cryogenic processing.

Alloy Disadvantages
Despite the huge number of positive characteristics, the material has some disadvantages:

High price. Knives of the highest price category are made from this steel. It is used by major manufacturers. Although some private craftsmen produce products from this alloy in small batches. For the production of kitchen knives, as a rule, 

gets married.
Low resistance to corrosion. The composition contains a lot of carbon and little chromium, so the material can rust. This is a kind of payment for maximum hardness. Therefore, the knife requires proper and regular maintenance.
Sharpening the edge yourself is quite difficult. The steel is very hard and hard to sharpen. To do this, you need to use special grinding tools, such as diamond and elbor whetstones. The complexity of sharpening is one of the secondary factors in the high cost of finished products.
Risk of injury. When sharpened with a knife, it is very easy to cut yourself, so you should work with it carefully.
Small selection of models. Only a few large manufacturers and private craftsmen make knives from this alloy. At the moment, the company offers the largest number of models

Conclusions and advice
K390 steel is deservedly considered one of the best tool grades on the market for the production of cutting tools. However, products made from this material cannot be called a good choice for every person. Knives with blades from K390 are quite expensive, and the choice of models is small.

Large companies produce products in small batches, and individual craftsmen often produce them only to order. Therefore, such products can be recommended to professionals who understand steels and the features of their operation. Such a blade must be properly cared for, otherwise it can become rusty and pitted, which often affects not only the appearance, but also the performance.
A K390 knife should be handled with care, as a damaged cutting edge will be expensive to repair due to the difficulty of resharpening. Otherwise, K390 is an excellent powder steel for making premium quality knives.

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".
