There are different types of steel, each of which has its pluses and minuses.Therefore, you need to know, from a metal to buy this or that product is that it has served as long as possible.
became universal
the characteristics 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 processing.It is the combination of these criteria explains such a huge number of grades of steel and finished products.Since there are different priorities of the metal products (sometimes only need strength, ductility and sometimes only), the steel was originally selected by their chemical composition, and received final properties using further processing.
combination of qualities
processing modes are matched as closely as possible to every detail and, if necessary, and a small part of it.They depend usually on what takes place in the construction element and any load it experiences (friction, dynamic tension, compression).Accordingly, the set and goals: to hardness, ductility, or a combination of these qualities.Get the same hardness, strength, ductility possible for steels with different chemical compositions, but they can give a poor result for the other criteria.But one and the same brand of metal parts can be used for various purposes.So, for pirmeru steel 95X18 can be the basis for the manufacture of various parts, but with the same requirements for tensile strength and hardness.These items and details can be diverse: bushings, axles, bearings, but their best characteristics began to appear in the production of hunting knives.
features and capabilities
95X18 - one of the best and most practical steels used for the manufacture of blades with particularly strong performance.Typically, this is the product for hunters.People preferring the knives of the brand, make the choice not by chance.Even without delving into the intricacies of metallurgy, to help you better learn the blades of steel 95X18 reviews of other users, which can understand a lot.Namely, this is the optimal material for such products.
opened the chemical composition and properties of the alloy is not so long ago.But its growing popularity says a lot about the high performance of this material.Work with the steel mainly professional companies, as it is very capricious, her inherent defects such as burnout or insufficient vacation.To do this, we need people with good knowledge of the case and stalevarnogo modern precision equipment, which can afford only company professionally engaged in the manufacture of knives and other metal products.
Treatment forging
presence of chromium in its chemical composition advances in a number of high-strength steel or corrosion-resistant stainless steel.In addition, the steel is for 95X18 forging.For any of the metal structure, this procedure is a "treatment" for many diseases, the most common of which are micro-cracks, filling the pores harmful elements hydrogen, oxygen, and, of course, job (not a busy place the atom, which forms a cavity).Besides the "disease", forging helps get rid of chemical and dendritic segregation, more tightly "equip" all the molecules.With this structuring hard metal grain refinement occurs.This allows to increase the ductility without reducing strength.After that, a steel 95X18 characteristics, capable of withstanding heavy loads, even on a bend.
form of a knife is as important
Features cutting products complement and enhance functionality.They properly distribute the load and make the use of the knife easy and convenient.In the manufacture of blade attaches great importance to the shape, size, edge grinding method and a method for fixing the handle.Each of these items has a more detailed tools.They increase convenience and enhance the artistic value of the product.There is a direct dependence on the thickness of the blade and the cutting quality.The thinner the blade, the better they perform minor works.
production technology
steel 95X18, knives which are obtained with a very strong and durable edge must go through several stages of processing.The work begins by obtaining castings of small size, which is annealed before forging (preform is heated to a temperature of 885-920 degrees Celsius, and held for 1-2 hours).It is very important not to burn the metal.If this happens, the workpiece is not subject to further processing.Only after such exposure olives ready for forging.Because it is formed of the desired plate size.Plus given machining allowance (grinding, polishing).After finishing the forging preform is rapidly cooled in the engine oil.This is called hardening.At this stage, the steel has a very high fragility, and if not removed, the metal at a mild shock will crumble like glass.Maybe sometimes he found work novice master, but mostly steel 95X18 reviews received from customers are positive.Procedure holiday is heating the workpiece, but to lower temperatures - only up to 200-300 degrees Celsius.
Education edge
cutting edge of the knife gets its shape in two passes.The first approach allows you to get only the initial size, the second - more accurate.Immediately after release of the first final machining is performed.The blade on the machine grinds to fit your needs.Steel 95X18, heat treatment which takes place in four stages, makes the final properties after the second release in which removed all the stress - and most metal becomes malleable.For this purpose the finished blade is maintained at a temperature of 150 degrees for 1-2 hours.Cooling air passes.To decorate the blade distinctive patterns can be carried out acid etching.
Care knives
Despite its hardness and strength, steel is subject to a slow destruction.Of course, this process takes more than a dozen or even a hundred years, but it can be minimized by accelerating improper care.
steel 95X18, having in its composition high chromium content, is remarkable for its resistance to corrosion, which increases the service life.Products from it also have this feature, but nevertheless, as the steel itself, and the design features of the knife to him required a careful attitude.
- mechanical load .Do not use the knife for other purposes.Pressures, calculated on the handle and the blade edge may destroy many materials, including very strong (wood, wire, and so on. D.), But primarily suffer sharpening and blade curvature.
- Moisture, moisture, acidic environment. Although steel 95X18 corrosion-resistant, prolonged contact with a solution with a high salt content adversely affects the surface.Similarly, as long stay in a damp place.
Technology of knives, as well as other steel items subject to state standards, technological maps and instructions.This type of steel is highly valued not only on the territory of Russia.It is just as easy to compete with foreign brands, and many of them are superior to the basic parameters.But despite this, the product of each master has its differences.This suggests that working with metal is not only a technological process, primarily a vocation.
