K110 steel for knives - features, pros and cons

At the moment, there are many possible materials for the production of knives. Depending on the purpose of production, different materials are used. Moreover, the content of the main substances of different grades of steel can differ significantly. The most typical grades of steel are high-carbon types of steel. Among them, you can find many types of materials that differ among themselves in the number of additional elements. One of the best grades of steel for hunting knives is K1100 from the Austrian company Böhler.

Composition and features
Böhler K110 steel is a high-carbon composition with a high chromium content. The metal is stamped by the method of cold stamping. Metal is produced by one of the largest metallurgical concerns in the world. Factories are located in Europe, North and South America.

In the production of K110, the technology of electroslag remelting is used. Due to this, the quality of the material increases significantly. Due to the presence of various undesirable impurities, serious defects may appear during mechanical forging. To avoid this, the method of electroslag remelting is used. During electroslag remelting, before the start of hardening, the melt is passed through a layer of special slag, which removes foreign elements from the molten metal, such as phosphorus, sulfur, and much more.

The method of electroslag remelting provides the final result with low levels of segregation, purity and homogeneity of the structure. In Böhler K110, the percentage of harmful impurities is significantly reduced and the compounds of metals and non-metals with carbon are evenly distributed.

Therefore, such a metal has a complex composition and is able to withstand even very thin corners during forging. One of the main advantages is extremely high strength and viscosity. It is preferable to harden such material in the air. If necessary, the nitriding method is used. Böhler K100 is used for forging knife products of the medium and high price segment.
Metal composition:

It contains 1.5% carbon, which provides higher strength and hardness.
Chromium content is 12%. This metal provides an increased ability of steel to be hardened, resistance to rusting and wear.
Molybdenum 0.8% is used for the production of high-speed steel. It significantly increases the rigidity of the blade, makes it resistant to high temperatures.
The percentage share of vanadium is 1%. This chemical element has high strength. Strengthens the elastic characteristics of the material and makes it resistant to various aggressive environments.
Manganese - 0.35%. Manganese is used during smelting. It significantly increases the hardness of the material. A characteristic feature of manganese is that various objects requiring high strength are made from steel with a high content of the chemical element. For example, safes, rails and much more.
Böhler K110

Main advantages
Any steel is an alloy of iron and carbon, but their ratio in the substance will directly affect the characteristics of the finished product. This type of material is produced by electroslag remelting. And due to the high content of impurities, the increased strength of the material is formed.

The main advantages of K110 steel from Böhler include:

• The main requirement that applies to all knives is sharpening. However, the sharper you sharpen the knife, the faster it will dull. However, this rule does not apply to K110 knives. Due to the high concentration of chromium in this steel, the resistance to wear is significantly increased. Therefore, the cutting edge will always be sharp. However, the use of such impurities reduces corrosion resistance. Although the knife will not rust very quickly.
• The presence of a high percentage of molybdenum in the composition provides the material with the uniformity and homogeneity of steel. This is very important for a knife. A small amount of vanadium increases the strength and durability of the material, and manganese in contact with chromium significantly increases strength.
• After many tests, it was established that even after many processing of bones and opening of cans, practically no serrations appear on the blade. The blade continues to be able to cut the newspaper under its own weight.
• Due to the combination of various impurities in the composition of the substance and the method of manufacturing steel, knives made of this material are distinguished by an extremely long service life.
• Increased resistance of the blade to various aggressive environments, which include some internal organs of animals. Therefore, the knife will not darken and rust for a long time.

The main disadvantages
The disadvantages include:

• It does not have high breaking strength. Therefore, it is undesirable to throw products, check for the ability to bend.
• Blades from this material are usually made with a small size and a narrow focus. These are hunting knives specially prepared for processing carcasses. They are usually used by the inhabitants of Siberia and the North. However, the sword will be able to show its excellent properties only with competent preparation and sharpening. Otherwise, it is very easy to spoil the cutting edge. However, if such care is provided, knives made of K110 will be equal in characteristics to blades made of higher quality steel.

Conclusion
K110 from Böhler  from the Austrian manufacturer is one of the highest quality products for forging knives. Despite the demanding care of the blade and the mandatory condition to dry thoroughly after contact with water, a knife made of such metal will serve for a very long time in the right hands. Therefore, it is definitely worth buying K110 knives and tools from the Austrian manufacturer. They can last a long time.

​WHAT ARE MICARTA AND G10 AND HOW THESE COMPOSITE MATERIALS DIFFER FROM EACH OTHER

Micarta 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) or other materials of a similar structure. Mycard is registered as a trademark of Paper International. Getinax is considered its Russian counterpart. This is a high-grade textile production textolite. Its color depends on the resin and material used for gluing. If you change the color of these components, you can get different and often quite fancy color compositions. But if we are talking about combat knives, then black, brown and olive-green colors prevail in this regard.

Micarta on a linen base has a more attractive optical effect when grinding the fibers. After grinding, the surface can be polished or sandblasted. In the first version, the surface will be silky. It is pleasant to the hand, smooth and warm to the touch. And in the second - it is rough and has a matte shade, in addition, it is securely held in the hand.

Main characteristics of Micarta:

• increased water resistance;
• excellent resistance to temperature changes;
• strength to mechanical processing;
• dense structure that does not absorb odors;
• the microrelief of the material does not slip in the hand even on a wet surface;
• tight fit to the blade, which leaves absolutely no gaps and prevents product residues and harmful microorganisms from accumulating.

Micarta is a relatively soft material and requires careful manual handling. Therefore, it is used in the production of handles for expensive knives. Most Western firms use mikart to manufacture the handles of combat and tactical knives that are supplied to the army. Improper use of mikart can lead to scratches.

G10 is a light, hard and stiff material with a textured surface that is used in the manufacture of handles for both folding knives and fixed blade knives. It is created from a fiberglass-reinforced, pressure-immersed compound. G10 is characterized by good strength and moisture resistance. This material can be painted in different colors and even in layers.

After the finishing stage of the handle or pads made of G10, the surface often turns gray and dull. To restore the colors to their former brightness, simply wipe the surface of the handle with oil. The finished G10 cover or handle can be sandblasted. As a result of the impact of the sand grains, the resins are compacted, stuck inside and reveal the structure of fiberglass. Such a rough surface contributes to a better grip and does not slip even when wet.

G10 and Micarta have a similar composition and external similarity. But the first material is not as flammable as the second. In terms of tensile strength, Micarta, unlike G10, is considered a weaker material. But still, it withstands very serious loads.

____________________________

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-Сomposite-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 handling. 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".

Heat treatment. What is good and what is bad.

As a rule, when buying a knife, a typical customer will definitely ask two questions:

1. What steel is the knife made of?
2. What is the hardness?

That is, even a non-specialist somewhere in the depths of his soul understands that iron glands are different and can be processed in different ways. The latter, however, is obviously not for everyone.

Very often you can see statements like "I just bought a knife with 95X18 - it's a complete threshing floor, it crumbles on sausage, it's dull on oil." And then - "But you're driving, I've sorted out my three boars and at least henna." In general, the degree of user satisfaction with a knife is an extremely multifaceted issue, but it also includes steel and its maintenance. Which can be different. Sometimes strongly.

So what is heat treatment and what is it eaten with?

Well, it is already clear from the name that this term describes many methods of processing materials based on changing their structure (and, accordingly, properties) under the influence of temperatures. Often when applied to the finished product, this is often referred to as "tempering", although the actual tempering is only one of the stages. Sometimes, including hot deformation, all this is called TMO (thermomechanical treatment), which is mostly fundamentally incorrect. Heat treatment usually includes several stages (sometimes several dozen). They all have different goals and different modes. Adding to the confusion is the fact that in the theory of heat treatment and in practice quite often individual processes have different names depending on the purpose and place in the technological cycle. We will not go into the slums, we are rather interested in the main stages and their regimes from the point of view of the impact on the final result.

I think that it will be easier to analyze it on the example of a typical blade production technology (with an indication of the main technological processes), which is used by the vast majority of Russian (and global) manufacturers. Consider a typical scheme used by private craftsmen and small-scale manufacturers.

(Forging)
1. Normalization (sometimes + high leave)
(cutting blanks)
2. Annealing or TCO.
3. Hardening with MKO
4. High vacation
5. Hardening
6. Cryo treatment
7. Resultant vacation
(Rough grinding)
8. Vacation after grinding
(clean grinding and proofing)

In the event that it is processed by cutting, there may be additional vacations (or dropped).

Let's consider the influence of individual stages on the properties and quality of products.

1. Normalization (sometimes + high leave) - allows you to bring the structure of the steel "to a common denominator" from which you can dance further, relieve tension, grind the grain, in some cases remove the carbide mesh or obtain the necessary hardness for processing. It is carried out in the form of heating to temperatures above the temperature of phase transformations (often to temperatures that cause significant dissolution of carbides) and cooling in still air. At the same time, many steels are able to be roasted and obtain high hardness - in this case, a high release is added.

2. Annealing or TCO – Allows to grind the grain, reduce the hardness to minimum values ​​(for processing by cutting or cold deformation), remove residual stress. It is carried out by heating to temperatures slightly above the temperature of phase transformations (in some cases - the intercritical region) and slow cooling to the temperature at which pearlite decomposition ends. It is often beneficial to replace annealing with thermocycling - repeated heating-cooling cycles to temperatures above/below the phase transformation temperatures, respectively. Such processing allows you to significantly grind the grain to a greater extent and, as a result, to obtain noticeably the best fur. Characteristics.

3. Hardening with MKO. It allows to significantly reduce the leash and warping of parts, thanks to the closing of micropores, in some cases, it slightly increases the hardness and fur. Steel indicators. It is performed as "soft" quenching from the intercritical region, as a rule, by cooling in oil.

4. High vacation (from the point of view of maintenance theory - pre-critical annealing) - relieves tension after fur. processing, which prepares the structure of the steel for hardening, in some cases reduces the hardness of the steel to minimum values.

5. Hardening - The main stage of maintenance. It consists in heating to temperatures above the phase transformation temperatures and, as a rule, causing significant dissolution of carbides, which create the necessary saturation of the solid solution with carbon and alloying elements, and rapid cooling (at a speed above the critical), which fixes this solid supersaturated solution.

6. Cryotreatment - cooling the product to low temperatures (usually -78 - 196C). It is intended to enable a more complete transformation of residual austenite, which increases hardness, resistance to crumpling and reduces the risk of austenite transformation during operation, but may reduce viscosity.

7. The resulting vacation - forms the final properties of the blade. Heating is usually carried out to relatively low temperatures (sometimes medium temperatures). When hardening on Tue

8. Vacation after grinding - relieves grinding stresses and sometimes stabilizes the austenite formed during grinding.

Not all stages are always necessary, some can partially or completely replace each other - it all depends on the steel and the technological cycle. In the case of the purchase of semi-finished products, a significant part of maintenance has already been done at the enterprise - manufacturers.

Maintenance stages are usually divided into preliminary and resulting maintenance. The resulting MOT forms the properties of the finished product (as a rule, this is all, starting from the last high-temperature stage - hardening), the task of MOT is to ensure the necessary technological properties and prepare the structure for the resulting MOT.

Of course, it is the resulting maintenance that most affects the "basic" properties of the steel, but it is the maintenance that often allows you to "squeeze" the maximum of what it is capable of from the steel.

Of course, there are no free cakes. As maintenance becomes more complicated, labor costs, equipment loading, etc. increase. Which inevitably leads to an increase in the price of products. Often reusable. Therefore, it is too optimistic to look for diamonds in the middle of the thicket. On the other hand, trying to squeeze the maximum can lead to such costs that the product acquires the status of "exclusive" with a corresponding price. We have to stop somewhere. Where exactly - each manufacturer decides for himself. More precisely, where his target buyer stops.

Let's consider the main options.

1. Shackled, heated in a furnace until bright yellow-hot, put in oil. I held it over the coal for 5 minutes - that's all... In this case, it is quite optimistic to count on at least an average result for this steel. With great experience, everything is possible...

2. Gave it to "some thermist" from the defense plant. What and how he did with the railway - this is a big secret... The result - from complete abomination to very good, although with a noticeable advantage of the first. Everyone decides on personnel.

3. There is a stove, there is a "data sheet", there is a strip of bourgeois steel. Knowledge and understanding of what and how - no. If you don't mow particularly hard, you can get a good result. Especially with modern steels - they are usually quite error tolerant.

4. The same + minimal ideas about what, where and why. As a rule, by accumulating and understanding one's own and other people's experience and personal responsibility, it is possible to obtain consistently good results.

5. Have a clear understanding of the subject and/or vast personal experience. Plus interest in the result and personal responsibility. These are prerequisites for obtaining stable results that are significantly above average. The author's maintenance schemes often allow you to squeeze much more out of the steels than what is expected of them.

6. Blades - champions also require some luck.

Let's consider the main errors during maintenance and their impact on product quality.

1. Insufficient hardness - as a rule, the result of underheating during hardening (rarely - overheating) or excessively high relaxation. In moderate forms, it is found on inexpensive knives as a compensator for overly simplified maintenance.

2. Excessive hardness and fragility of "Perecal". But here everything is more complicated. It is often not a question of high hardness, but of overheating during hardening (or not carried out PTO), when the steel gets too large a grain. Actually, hardness is not the only indicator of the quality of maintenance - the same hardness can be reached in different ways and with different results. So statements like "A knife higher than 58HRc is as fragile as glass" should be taken with healthy skepticism.

3. Carbonless layer. In the absence of protective atmospheres/coatings or vacuum equipment, there is almost always. When etched, it usually looks noticeably lighter than the background. With proper planning of the technical process, this layer is removed, but in some cases (for example, when hardening a thinly reduced workpiece or performing a knife with "chisel" sharpening without removing the decarburized layer), it can appear on the RK, with the saddest consequences for the latter. Sometimes it can cause errors regarding the hardness - there it will be noticeably less than on the body of the blade and RK.

4. Cracks. They can appear at various stages of production, most often during forging, hardening or grinding. It is an unconditional irreparable marriage. The sale of such a blade (with the exception of VERY rare cases on multilayer swords or damascus) is a direct indication of the manufacturer's attitude to the matter. Crazy attitude.

5. Floods and warping. At long range they are practically inevitable, at short sword they are permissible to a certain extent.

In conclusion, some real stories about different knives.

1. During tempering, blacksmith A screws several dozen blanks with hairpins, throws them into the furnace, and goes to drink vodka. After a few hours, he returns, throws the "sandwich" into the oil tank, and goes to drink vodka. He doesn't take vacations - why is there anyway 58...

2. For many years, blacksmith B has been forging X12MF at temperatures 50 degrees higher than optimal. To a reasonable question about the reasons - "I always do this, people don't complain."

3. Enthusiast B decided to carry out cryoprocessing by quenching the pre-heated workpiece in liquid nitrogen. On the offer to first find the value of the heat of vaporization for liquid nitrogen in two days, he thoughtfully expressed "Bah."

4. Blacksmith G forges each workpiece differently. At the same time, he himself does not feel them and does not systematically collect reviews. Looking for a person...

5. When tempering EACH blade, in addition to the author's maintenance and testing for hardness, master D always controls breakage - just in case. This is a request for a responsible attitude to the matter, which manifests itself in other issues and finds its mark in the price of the products.

So, choosing a MOT, you choose a MANUFACTURER. Different masters may have different views on maintenance, but a responsible and self-respecting and consumer manufacturer will never sell a product with properties below a certain minimum. And in the case of marriage (which does not happen), he will make every effort to resolve the situation.

 G10 склотекстоліт

 G10 fiberglass

Glass textolite G10 is a material for creating knife handles. Glass textolite G10 is a composite material based on fiberglass and epoxy resin, used to create knife handles.

In the production of G10, fiberglass is soaked for some time in epoxy resins, after which the product is placed under a press for a long time.

As a result, we get a very strong, moisture-proof and impact-resistant material. G10 is a material that is excellent for processing and painting. G10 - used in their products by the vast majority of knife manufacturers and authors.

As an example, we can cite such companies as Spyderco, Benchmade, and among the authors who like to work with textotextolite Bob Terzuola, Duane Carillo and Mick Strider. In addition, almost all Emerson knives have G10 handles.

Before mounting G10 on the liners, the material is sandblasted and then impregnated with oil. G10 - the material is very tenacious and provides, apparently, a reliable hold of the knife in the hand. The disadvantages of the material include the rather aggressive attitude of knives with a G10 handle to trouser pockets.
