Chemical composition
Medium-carbon structural steel 38Х2Н2МА of improved quality, alloyed with chromium, nickel and molybdenum, in the CIS countries is produced in accordance with the requirements of GOST 4543. The steel composition includes:
| Element | Carbon | Silicon | Manganese | Chrome | Nickel | Molybdenum | Copper |
|---|---|---|---|---|---|---|---|
| Presence in steel, % | 0,33…0,40 | 0,17…0,37 | 0,25…0,50 | 1,30…1,70 | 1,30…1,70 | 0,20…0,30 | Up to 0.30 |
There are several known analogues of this steel. Practically similar chemistry is produced in Poland as steel 36hnm. The other analogues are 34CrNiMo6 (1.6582) and 40NiCrMo7 alloy steels, melted by European steel makers in accordance with EN 10083−3. The composition of these steels differs from 38Cr2H2MA as is shown in the table below (data for 34CrNiMo6):
| Element | Carbon | Carbon, silicon | Carbon, silicon | Chromium | Nickel | Molybdenum |
|---|---|---|---|---|---|---|
| Presence in steel, % | 0,30…0,38 | Up to 0.35 | 0,50…0,80 | 1,30…1,70 | 1,30…1,70 | 0,15…0,30 |

Properties and application
The steels under consideration are designed for producing forgings and finished parts with high temperature resistance. The steel is well heat treated, the main type of heat treatment is considered to be refinement. Improved shafts, axles, gears, and other similar products can have considerable size and complex configuration. The weldability of steel is limited.
The main mechanical values of steels of this type that have been quenched and tempered are:
- Tensile strength, MPa — 850…900;
- yield strength, MPa — 735…785;
- Relative elongation, % — 11…13;
- Relative narrowing of cross-section, % — 39…40;
- Impact viscosity, kJ/m2 — 55…60;
- Brinell hardness, NV — 270…320.
