GOST 5632-2014
State standard 5632-2014 normalizes the production of steel alloys of the following groups:
| Grade of steels. | Technical characteristics. |
| Corrosion-resistant . | Resistance against electrochemical and chemical corrosion (atmospheric, soil, alkaline, acid, salt), intercrystalline corrosion, stress corrosion, etc; |
| Heat-resistant (scale-resistant) | Resistant against chemical destruction of the surface in gas environments at temperatures above 550 °C, operating under no or lightly loaded conditions. |
| Heat-resistant | Operating in loaded condition at high temperatures for a certain period of time and at the same time are sufficiently heat-resistant. |
| Relaxation-resistant | Characterized by the full relaxation of the stresses that have been accumulated in the part for a certain period of time at temperatures of 400 ... 6000 C and at the given initial stresses. |

Steel grades
GOST 5632-2014 establishes the following classes of steel alloys that differ in their microstructure:
Martensitic - steels with a basic structure of martensite;
Martensitic-ferritic - the structure contains at least 10% ferrite in addition to martensite;
Ferritic - class of steels with ferrite structure, without direct and inverse α↔β transformations);
Austenitic-martensitic - a class of steels with austenite and martensite structure, the amount of which can be changed in a wide range;
Austenitic-ferritic - steel alloys having the structure of austenite and ferrite (ferrite over 10%);
Austenitic - steels having the structure of stable austenite.
The subdivision of steel into classes according to the structural features is arbitrary, because it involves only one heat treatment, namely, cooling in the air after high-temperature heating (over 900 ° C) of samples of small sizes.
