Alloy steel — is iron-based, which quality is improved balanced combination of 10−12 alloying elements. Also the method of production and processing that give the material the necessary structure and consumer properties. The presence of major alloying elements are reflected in the marking. Letter, And indicates the presence of nitrogen, n — of aluminium — tungsten, f — vanadium, cobalt, C — silicon, G — manganese, M — molybdenum, D — copper, B — niobium, E — selenium, N — Nickel, T — titanium P — phosphorus, X — chromium, cerium, C — Zirconia. The numbers after the letters indicate the percentage of the element. If the percentage is less than 1.5% of the figure for alphabetic index not stamped. Carbon percentage point at the beginning of the alloy in hundredths of percent (structural steel) or tenths (tool steel). Alloy steel belongs to the category of heat-resistant materials. High quality steel allow to use it in an oxidizing atmosphere at very high temperatures, about 1000 °C. Chromium and Nickel, the total percentage of which in the alloy may reach 45%, protect the surface of structures, from wet corrosion and corrosion cracking in alkaline and chloride environments, gives resistance to intergranular corrosion. Supplements silicon, manganese, titanium additionally improve manufacturability and performance.
Due to the high technological and operating characteristics, alloy steel is widely used by engineering, thermal power, where the production process involves high temperatures I. aggressive environments. Thanks to such materials of new generation have the opportunity to improve technological processes of production and to ensure long term reliable operation of the whole complex of equipment.
