The main products of modern companies is of rolling alloy steel, without which today can not do any one industry. Alloy steel is high performance, resulting in the manufacturing process. In order to achieve the desired properties of the additive are made optimum number of specialized additives. After adding to the melt necessary components obtained alloy steel, the main features of which are the excellent mechanical and technological characteristics.
Today, in the wake of economic recovery to consumers it offers a large selection of different grades of steel with alloy additions, such as:
— Chemically bound nitrogen;
Of course the list of alloying components is much wider than indicated, but as a rule, are the main types of items listed above. Dopant possible to obtain a structural steel or tool type essential in the performance of demanding applications.
Experts identify three main groups of alloy steels:
— Low-alloy steel (additive content barely reaches 2.5%);
— Srednelegirovannoj steel (the percentage of the maximum number of additives ranging from 2.5 — 10%)
— High-alloy steel in which the presence of additives to be equal to half the mass of the finished material.
By selecting the required literacy necessary components, alloy structural or highly alloyed tool steels.
It is necessary to understand, how is the marking of alloy steels. Marking is applied to specific locations or product designs before sending it to realization. Used as numerical and letter designations. With knowledge of the process of marking principles of selection of necessary materials goes much faster. Classification of alloy steels provides for 4 categories, which correspond to one of the capital letters of the alphabet, it is located in front of the rest of the notation symbols:
— Electrical steel — denoted by the letter E;
— Ball-bearing steel — is designated by the letter W;
— Cutting steel is marked with the letter A;
— High-speed steel — R.
You can find the marking letter A — evidence of the presence of nitrogen in the steel, and the location of the letters depends on the quality of steel directly. So stainless steel symbol should be placed at the end of lines. If it is just information about the content of nitrogen, «A» is located in the middle of the percentage coefficient of abbreviations in numerical form. The marking contains capital letters of the alloying components with digital percentage designation. Niobium — B tungsten — B, manganese — T, copper — D, selenium — E, cobalt — K molybdenum — M Ni — H, phosphorus — P cerium — P silicon — C, Ti — T, vanadium — F, chrome — the X, Zr — C, aluminum — Y. The above marking has documented the relevant GOST.
Dosing steel industry depends on its class and a set of attributes. Here are the classes.
— Pearlitic found its application in mechanical engineering as a material for vehicle parts or performing household structures fragments.
— Ausistentny class assumes that the alloyed stainless steel acquires properties increased resistance to corrosion due to chromium in the composition. It is used in heavy and light industry, as well as for products of home appliances;
— Ferritic steels are the most demanded mind, since they not only highly resistant to corrosion and high temperatures, due to a significant percentage of chromium and nickel in the composition.
