In today's world steel knife plays an important role in human life, since the data subject has to face almost throughout the entire existence.Now used for the manufacture of a variety of processing technologies, which implies the presence of alloys.All the added impurities are designed to improve the quality produced products.Scientists throughout the world are dreaming to ensure that the quality of the alloys reached a new level, so that there are intricate technology and formulations.Currently, there are certain grades of steel for knives, allowing you to select the best option depending on the application.
The permanent struggle for physical properties such as hardness, heat resistance and durability.High-quality steel for the blades should provide good resistance to penetration into other bodies.That is, it is bound to suffer serious stress without deforming or losing its shape.In addition, considerable importance is the ability of a material to wear, which is primarily due to the content of the hardest carbides (vanadium, molybdenum and tungsten).For this reason, the brand CPM 10V and CPM S90V have high wear resistance.
Each chemical element in its effect on steel for the blades, giving it a particular quality.One of the basic components of the carbon is considered to be, in many respects predetermines the main characteristics.Thanks to this item it is possible to temper the steel knife.Hardness will depend largely on its ratio.However, at the same time due to exposure to carbon increases the corrosion of the metal.Typically, the presence of carbon should not be less than 0.6 percent, but many manufacturers do not pay special attention to this figure, producing low-quality products with low cost.
Another common and necessary element - chromium.With it is possible to successfully resist corrosion, adding the steel knife.If the amount of the component exceeds 14 percent, it can be assumed that it is stainless steel products.However, a high content of chromium adversely affects the strength characteristics.As dopant often used molybdenum, capable of enhancing the heat resistance and corrosion resistance.Certainly, it has a positive effect on any steel knife.
An interesting element appears vanadium, which helps to enrich the physical properties of various alloys.Its main function is to greatly increase the wear resistance and durability.Steel knife enriched this element is able to maintain a long period of cutting quality.However, it should be noted that such a sharpening blade becomes more laborious.In many cases, it includes a cobalt alloy, characterized by high durability.Its usually contain marks N690 and VG-10.Also steel knife can include nickel, nitrogen, sulfur, silicon, titanium and many other chemical elements.
