What would be the steel we may have to consider, each has its own set of properties and characteristics that are appropriate for the conditions. Thanks to the professionalism of producers of steel finished product combines quality and optimum properties. However, to achieve the best characteristics from all directions will not work, so you have to sacrifice something. For example, soft iron for long stays sharp, and to sharpen this blade will not be difficult. More solid material can be prone to chipping. In cases when the alloy has a complex chemical composition, its production and processing become time consuming and, as a consequence, the cost of the finished product increases. Thus, the steel for making knives, which meets several specific requirements, it becomes more expensive to manufacture.
What materials will be used in the manufacture of a particular product will depend on how often he will become stupid, how difficult is the process of sharpening, what will be its resistance to bending and how easy it is to break. Not Here it all depends on the grade of steel for knives. Characteristics such as softness, the ability to bend, blunt, break can depend on heat treatment. Proof of that is the fact that well-established market manufacturers are producing high quality knives using a stamp 420. Here are some of them:
All izgotoviteli develops its own technologies of production and processing of steel, through which to achieve its goals.

Many people believe that the blade has excellent sharpness, is the best. It is more important to pay attention to the wear resistance, when compared grades of steel for knives. Characteristics such as wear resistance, are directly dependent on the amount of carbon in the material. In the most ordinary carbon steel, the maximum hardness observed when the carbon in it is 0.7 percent. If you increase this percentage in the production, it is possible to increase resistance to wear.
By experience and the scientific methods metallurgists get alloys that meet the requirements of the market. For example, to increase the resistance of the material is possible thanks to the use of alloying dobavok:
Due to the introduction of small quantities of other elements in the steel alloy more durable and wear resistant compared to ordinary carbon. However, you need to understand that the inclusion in the composition of these supplements makes sense to a certain point. If the threshold concentration is exceeded, the steel starts losing its strength properties.
The best an additional element called molybdenum. Alloying of steel with the use of this component allows an improvement of both strength and toughness at the same time. An excellent example of this can be notorious Japanese swords, known for their characteristics. The molybdenum content in them reach up to eight percent.
Vanadium, chromium, tungsten improves the strength characteristics, but at the same time make the steel more brittle. Doping of chromium (above 13%) allows to give the material resistance to corrosion along with the increase of cutting properties. You must understand that such improvements will have to sacrifice resistance to breaking.
If you raise the question, what is the best steel for a knife, it can be concluded that stainless steel 440C is the best option. Its properties include the ability of long time to keep grinding. Such material is, however, inferior in wear resistance and elasticity alloy such as 154 CM steel for knives. The comparison also can be made with such brands as at S-34, BG-42. Their composition does not contain the quantity of chromium, however molybdenum it contains up to 4%. Steel for making knives of these brands is called ball-bearing stainless. This is the name of these alloys was due to the fact that the properties of durability, they are beneficial to stand out among others.
Knife - the kind that even the most peaceful people I use almost every day. One of the oldest inventions of mankind through the depths of the centuries, came to the XXI century, is not very stable in form. But alloys invented very much. Consider the popular brands of steel and their characteristics in order to understand, what is the best steel for a knife.
Let us Consider it. If you choose the most common models of domestic kitchen knives and make an analysis of what they use steel for knives, the comparison will understandthat's 40X13. It is perfect for kitchen use due to the fact that will not rust and well tochitsya. The above material 420 is its foreign counterpart. Steel for a kitchen knife is not its only purpose. Scalpels (along with other surgical instruments) also are made of “medical steel”, and it is a well-known name.
Foreign counterpart – 425. This steel is a good half of all Russian knives. It is unlikely that products made of it, once rust. And all thanks to the fact that the knives from this steel have high anti-corrosion properties. Their lifespan is measured in decades.
Becoming more popular in the manufacture of cutting blades. Characteristics of steels for knives of this brand close to the previous alloy, but have some drawbacks. Often used for making medical instruments and high-quality knives as domestic purposes, industrial, and even military. If you produce proper heat treatment of this steel, it is possible to output a very durable product.
Stainless steel, with some features for claims processing. If in the production of consider all the nuances, you can get a durable and flexible knife. Sharpening these blades lend themselves to bad, but long blunt. Possible manifestation of signs of corrosion, but only after prolonged exposure to moisture.
Refers to the type of spring steel. If you have thought about how to make a knife, she's probably familiar to you, as it is considered very popular on various forums for homemade production. Kitchen tools made of it are very rare, as it is susceptible to corrosion. Resistance to rust are trying to increase thanks to various coatings, but is not a panacea.
The Most budget and most common option. Maybe due to this the majority of Chinese manufacturers use it. This steel is considered stainless at one hundred percent. Proper heat treatment allows to achieve excellent characteristics for blades of this steel, as evidenced by the selection of popular manufacturers mentioned above. For example, this material can be clearly seen that the chemical composition plays a major role. Life, in spite of its low cost, large enough.
This high carbon steel is widely used for the manufacture of knives. Many famous producers prefer this steel because of the fact that it is easily processed and has good anti-corrosion properties. Often, the blades will be blunted. However, in order to restore a sharp cutting edge, do not need a lot of effort.
Blades of steel М390 can boast a high cutting and wear-resistant properties. Is very popular among manufacturers of blades. Such steel, in addition to the production of knives used for the manufacture of surgical instruments, which meet high requirements. Due to the doping of chromium, this steel does not rust. It should be noted that is not only to make knives from steel М390. This is a very popular steel in the industrial production of devices and machines to work with solid materials.
Distinguish several varieties, denoted by A, b and C. Note brand 440C, which is a high-tech steel. Each species has its own percentage of carbon to 0.75%, 0.90% and 1.20 percent.
The Japanese equivalent of alloy 440. Same as the previous option, has several varieties, which differ by the amount of carbon: AUS-6, -8, -10.
The die Steel of this type has a very high wear resistance and durability. The blades of steel KH12MF subject to corrosion, because of what their use in the kitchen is undesirable. These knives boast a good cutting properties and ability to long to lose its sharpness. The blades of steel KH12MF especially hunters, who without a quality tool can not do.
This is the highest category of steel produced in Japan. It combines high strength and toughness, along with hardness, which has no analogues in the world. It is used by several manufacturers for making their best knives. Accordingly, the price of the finished product is very high. Therefore, in the domestic market of such products have very little.
The Developers of this alloy is dick Barber and Chris Reeve. For the production of steel use of vanadium carbides. Through their use you can achieve the best grain steel and greater strength. This development has adopted many modern knife manufacturers.
Widely used for the manufacture of knives used in the sea, where constant exposure to salt water can cause rust. Not very comfortable she is in treatment. A well-known manufacturer Spyderco makes extensive use of this grade of steel for their knives. What is the best steel for a knife used by sailors? Of Course - N-1.
Included in the list of the most high-tech materials. Steel 154 – originalAmerican Razrabotka with high performance and same price. AT S-34 is a Hitachi product. Is the Japanese equivalent of 154 steel. It is believed that these brands occupy a leading position in the world.
If you ask the professionals, what is the best steel for a knife will tell you – damask or damask. Since ancient times, to indicate the excellent quality of the blade, simply said he was from Damascus steel. The quality of knives made of Damascus steel depends on the professionalism of Smith, proper heat treatment and grinding. If you compare the Damascus blades with Damascene, it will be possible to note the superiority of the former in strength. If you talk about cutting properties, they are equal.
I Wonder what the lost secret of damask steel was found in 1841 by P. I. Anosov, Russian Metallurgist. Thanks to him, revived the manufacture of weapons of this steel at the Zlatoust factory. Even in our time, the swords produced there is called the best. During the Soviet Union the production of high-quality knives ceased to exist as such due to the policy of the state. Officially manufactured and then the production was poor quality and could hardly meet the demands of the hunter. Only by craftsmen who knew how to make a knife efficiently, it was possible to get a good blade.
Metallurgist who developed this material, named him in honor of his wife. At the time it was produced about 8 tons of this steel. After the death of the master the secret of this Bulat, possessing unique characteristics have been lost.
So, we found out what the steel making knives with centuries-old human companions.
