Tool steel


Alloy tool steel belongs to the category of heat-resistant materials. High quality steel allow to use it under heavy load at very high temperatures, about 1000 °C. Chromium, molybdenum, tungsten, vanadium, their total fraction in the alloy can reach 10%, gives the steel the required hardness and wear resistance. Supplements silicon, manganese, Nickel further improve the performance.


Alloy tool steel is based on iron, 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, In tungsten, f — vanadium, cobalt, 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 tenths of a percent. Tool alloy steel produced according to GOST 5950−2000.
