What is tool steel?
Tool Steel is a type of steel with mechanical properties that make the material desirable. The tool steels are remarkable for their hardness, the ability to maintain a sharp edge or resistance to reins and deformations. There are a number of alloys and carbon steels, usually produced by a product of heat treatment and extinguishing, which are suitable as steels on tools. The tool steel is produced in many different levels and can be used to make tools such as stamp, construction equipment and axes. In addition to the production of tools, it is also used in other applications that require materials with mechanical properties of Tool Steel. It categorizes each type of steel with a letter that indicates its properties or production methods, such as W for water steel or grades for shocks of durable steel. Each type of steel in these wide categories then receives an individual number followed by a letter.
the most common formThe tool steel is W, the form of carbon steel popular due to low costs. Some types of W-classes also include silicon, molybdenum or manganese to increase steel toughness. This is called water, because water is used during extinction, a step in the production process of many steels in which the heated steel is rapidly lowered the temperature. The W-3 tool steel is hard, but it tends to be fragile and does not happen well to temperatures above 302 ° F (150 ° C). Cheely with W-classes are commonly used to produce blades such as shear blades and razors; parts of machines for machines that do not meet or produce high temperatures; And tools such as hammers, Adlat exercises.
Stages A, O and D The steels are produced by cold processing, which is a process in which steel is subjected to mechanical voltage until it provides plastic deformation, which is a permanent change in steel microstructure. This process increases tensile strength and steel hardness while reducing its ductility and the resulting forms of steel commonly usedThey are for purposes such as blades and machinery. Oil class o Oil is oil, while the A-deck is decorated with air, methods that produce less distortion in steel than water load. The D-Decen's steel contains a large amount of chrome, which makes up 10 to 18 percent of the alloy. In addition to Chromia, steels are often alloyed by other metals, including manganese, tungsten and vanada, as non-metal, such as sulfur and phosphorus.
H-deck is a steel with warm work, created by causing plastic deformation in steel through extended exposure to high temperatures. These steel high strength and hardness, but slight distortion of the cooling process and thermal contraction makes them less suitable than the cooling steel for applications with very tight engineering tolerances. Chrome, tungsten and molybdenum are common elements of leggings in the steels of this class.
degrees T and M are types of high -speed steel, which is distinguished by its ability to maintain high hardness at high temperatures. This feature is well inA good for use in powered cutting instruments and pressing countries, where its resistance to the heat produced by friction allows you to operate at higher speeds than other steel. T-class steel is named for its high tungsten content, while the class M contains a high amount of molybdenum. Other alloyed elements common in these steels include vanadium, chrome and cobalt.
s-classes are steel tools that are characterized by their high resistance to shock. They have less carbon than other steel alloys, which reduces their resipostoje to abrasion, but increases their toughness. S-classes are used in devices such as jackhammers that must be able to withstand a strong impact.
Some tool steel signs have very specialized properties or purposes. F-Grade steel is a type of steel with water such as steel but has excellent wear resistance. In the injection of the casting and casting machines, steel is used by P-independent or plastic mold steel. L-deck or low alloySpecial steel is a very hard type of steel, which has a small cervical material and a very high iron content.
