Chemical composition
Steel grade 20Х2Н4А belongs to the group of chromium-nickel steels, which are melted in the CIS countries in accordance with GOST 4543 technical standards. The chemical composition of steel is as follows:
| Element | Carbon | Silicon | Manganese | Chrome | Nickel |
|---|---|---|---|---|---|
| Content in steel, % | 0,16…0,22 | 0,17…0,37 | 0,30…0,60 | 1,25…1,65 | 3,25…3,65 |
GOST 4543 specifies also the presence in the steel 20X2H4A metallurgical impurities — sulfur and phosphorus — content not more than 0,035%.
The European counterparts of this steel are: steel 20h2n4a of similar
Its European analogue steels are 20h2n4a steel of similar composition melted in Polish metallurgical plants and 20Cr2Ni4A steel produced in accordance with GB / T3077−1999 standard specifications. Chemical composition of this steel is given in the table below:

Properties and application
Alloy steels of the group under consideration are subjected to different heat treatment regimes. In the hardened state, after tempering they have the following physical and mechanical properties:
- Tensile strength, MPa — 1300;
- yield strength, MPa — 1100;
- Relative elongation, % — 9;
- Relative narrowing of cross-section, % — 45;
- Impact toughness, kJ/m2 — 800.
Rolled sheets and forgings from 20Cr2Ni4A, 20Cr2Ni4A, 20h2n4a steels are used for producing parts for automobiles, tractor engines and mechanical transmissions. Steels are well processed on machine tools, metal forming is effective only in hot condition.
