Steel 95x18: characteristics, reviews, heat treatment and knife manufacture

There are different types of steels, each of which has its pros and cons. Therefore, it is necessary to know from which metal to buy this or that product, so that it lasts as long as possible.

Steel universal

The geometry of the steel object corresponds to its geometry, but to a greater extent the structure of the metal, which in turn depends on its composition and the necessary thermal, chemical and mechanical treatment. It is the combination of these criteria that explains such a huge number of brands of steels and finished products. Since there are different priorities for the characteristics of metal products (sometimes only strength is needed, and sometimes only plasticity), initially steel is selected according to its chemical composition, and it gets the final properties by further processing.

A combination of qualities

Processing modes are selected as accurately as possible for each part, and if necessary also a small part thereof. They depend, as a rule, on the place in the construction of the element and what loads it experiences (friction, dynamic, stretching, compression). Proceeding from this, the goals are also set: to achieve firmness, plasticity, or a combination of these qualities. Get the same hardness, strength, ductility can be for steels with different chemical composition, but they can give unsatisfactory results by other criteria. But the same brand of metal can be used for parts for various purposes. So, to the pirmer, steel 95x18 can be the basis for the manufacture of various parts, but with the same requirements for the ultimate strength and hardness. These items and parts can be diverse: bushings, axles, bearings, but steel shows its best characteristics when making hunting knives.

Features and capabilities

95X18 is one of the best and practical steels used for the manufacture of knives with particularly strong performance. As a rule, these are products for hunters. People who give their preference to knives from this brand make their choice not by chance. Even without delving into the subtleties of metal science, they help to better learn knives from steel 95x18 reviews of other users, on which you can understand a lot. Namely: this is the most optimal material for such products.

They discovered the chemical composition and properties of this alloy not so long ago. But its growing popularity speaks volumes about the high rates of this material. Work with this steel is mainly professional companies, since it is very capricious, it is characterized by such defects as overheating or insufficient leave. This requires people with a good knowledge of steelmaking and modern precision equipment, which can only be allowed by a company professionally engaged in the manufacture of knives or other metal products.

Forging treatment

The presence of chromium in its chemical composition puts high-strength steel in a series of corrosion-resistant or stainless. In addition, steel 95x18 is designed for forging. For any structure of the metal, this procedure is a "cure" for many diseases, the most common of which are microcracks, pore filling with harmful elements of hydrogen, oxygen, and, of course, vacancies (the atom does not occupy the place that forms the cavity). In addition to "diseases", forging helps to get rid of chemical and dendritic segregation, more tightly "complete" all the molecules. With such a rigid structuring, the grinding of the grain of the metal takes place. This allows you to increase the ductility, without reducing the strength. After that, it has a steel of 95x18 characteristics, capable of withstanding large loads even for bending.

The shape of the knife is no less important

The design features of cutting products complement and increase the functionality. They correctly distribute the load and make the use of the knife easy and convenient. When manufacturing a blade, great importance is given to the shape, size, edge sharpening method and method of attaching the handle. Each of these points has more detailed adaptations. They increase the convenience and increase the artistic value of the product. There is a direct dependence on the thickness of the blade and the quality of cutting. The thinner the blade, the better they will perform small work.

Production technology

Steel 95x18, knives from which are obtained with a very strong and wear-resistant edge, must go through several stages of processing. The work begins with the production of a small casting, which is preheated before the beginning of the forging (the preform is heated to a temperature of 885-920 degrees Celsius and held for 1-2 hours). It is very important not to burn metal. If this happens, the workpiece is no longer subject to further processing. Only after such aging olives are ready for forging. A plate of the correct size is formed from it. Plus allowances are given for machining (sharpening, grinding). After the end of forging, the workpiece is quickly cooled in engine oil. This is called hardening. At this stage, the steel has a very high brittleness, and if it is not removed, the metal with a slight impact will crumble like glass. Maybe, sometimes the work of an inexperienced master occurs, but mostly steel 95x18 reviews Receives positive feedback from consumers. The tempering procedure is the heating of the workpiece, but already to lower temperatures - only up to 200-300 degrees Celsius.

Edge formation

The cutting edge of the knife gets its shape in two sets. The first approach allows obtaining only preliminary dimensions, the second - more accurate. Immediately after the first leave, the final machining is carried out . The blade on the machine is sewn to the desired dimensions. Steel 95x18, heat treatment Which passes in four stages, takes the final properties after the second tempering, in which all stresses are removed - and the metal becomes as plastic as possible. To do this, the finished blade is kept at a temperature of 150 degrees for 1-2 hours. Cooling takes place in the air. Etching with acid can be used to decorate the blade with unique patterns.

Care of knives

Despite its hardness and strength, steel is subject to slow destruction. Of course, this process lasts more than a dozen or even a hundred years, but it can be reduced to a minimum, accelerating by improper care.

Steel 95x18, having in its composition an increased content of chromium, is distinguished by its corrosion resistance, which increases the service life. Products from it also have this feature, but nevertheless both the steel itself and the structural features of the knife require careful treatment.

• Mechanical loads . Do not use the knife for other purposes. Loads designed for the handle, edge and blade can destroy many materials, including very strong materials (wood, wire, etc.), but the sharpening and curvature of the blade will be the first to suffer.
• Moisture, dampness, acidic environment. Despite the fact that steel 95x18 corrosion-resistant, prolonged contact with a solution with a high salt content negatively affects the surface. Just like a long stay in a humid place.

The technology of manufacturing knives, as well as other steel items, is subject to GOST, technological maps and instructions. This species has become highly valued not only in Russia. It just as easily competes with foreign brands and many of them are superior in basic parameters. But, despite this, the products of each master have their differences. This suggests that working with metal is not only a technological process, but primarily a vocation.
