Labeling of alloy steels

Lettering

The designation of alloyed steel in Russia consists of a combination of letters and numbers reflecting its percentage composition. The alloying elements have the following designations: Ni (N), Cr (X), Mn (G), Mo (M), Si ©, W (W), Ti (T), Ta (TT), V (F), Al (U), Cu (D), B (P), Co (K), Nb (B), Zr (Ts), Se (E), rare-earth metals (Ch).

Numerical marking ,

The number after the letter indicates the percentage content of the alloying element. If the number is not specified, then the alloying element is not more than 0.8-1.5%. The exceptions are molybdenum and vanadium (whose share in steels is usually up to 0.2-0.3%). In addition, boron (in an alloy with the letter P should be up to 0.01%). The first two digits of the structural quality alloy steels reflect the carbon content in hundredths of a percent.

Example: 03Cr16N15M3B is a highly alloyed steel that contains 0.03% C, 16% Cr, 15% Ni, up to 3% Mo and up to 1% Nb. A number of special steels have their own special designation: steels for ball bearings are marked with the letters (SHX), after which indicate the content of chromium in tenths of a percent; tool steels are designated by the letter (P), the next number reflects the percentage of tungsten, automotive steels are marked with the letter (A), the number indicates the carbon content in hundredths of a percent.
