Marking of alloy steels from the supplier Electro-steel-steel
The designation of alloy steel in Russia consists of a combination of letters and numbers reflecting its percentage composition. The alloying elements have the following designations: Ni (H), Cr (X), Mn (T), Mo (M), Siθ, W (B), Ti (T), Ta (TT), V (Ф), Al (U), Cu (D), B (P), Co (K), Nb (B), Zr ©, Se (E), rare earth metals (H).
The number after the letter indicates the percentage of the alloying element in. If the number is not specified, then the alloying additive is not more than 0.8−1.5%. Exceptions are molybdenum and vanadium (their share in steels is usually up to 0.2−0.3%). In addition, boron (in the alloy with the letter P should be up to 0.01%). In structural quality alloyed steels, the first two figures reflect the carbon content in hundredths of a percent.
Example: 03X16H15M3B is a high-alloy steel containing 0.03% C, 16% Cr, 15% Ni, up to 3% Mo and up to 1% Nb. A number of special steels have their special designation: Steels for ball bearings are marked with letters (SHX), after which the chromium content is indicated in tenths of a percent; Complexly alloyed tool steels are denoted by the letter (P), the next number reflects the percentage of tungsten; Automated steels are marked with the letter (A), and the number reflects the carbon content in hundredths of a percent.
In the warehouse of Electrovek-Steel LLC there is a wide range of high-quality rolled metal of standard and non-standard sizes. We supply products from alloyed alloys in retail and wholesale. All products are certified for compliance with the requirements of standards and technical conditions of operation. In the certificate, the manufacturer, number of drawings and product names, alloy grade, melting number, parts, chemical composition, mechanical properties and results of additional tests were noted. The implementation of orders — in the shortest possible time. Discounts are given to wholesale buyers.
