Chemical composition
Aluminum deoxidized structural alloyed steel 38ХМЯА grade is produced in CIS countries according to the GOST 4543, and has the following chemical composition:
| Element | Carbon | Silicon | Manganese | Chrome | Molybdenum | Aluminum | Nickel | Copper |
|---|---|---|---|---|---|---|---|---|
| Percentage content in steel | 0,35…0,42 | 0,20…0,45 | 0,30…0,60 | 1,35…1,65 | 0,15…0,25 | 0,70…1,10 | Up to 0.3 | Up to 0.3 |
As metallurgical impurities, there is sulfur and phosphorus in the composition of steel, the amount of which in the finished product should not exceed 0.025%.
The European analogue of 38CrMoA steel is steel 34CrAlMo5 (produced in accordance with European standards EN 84−70). Polish metallurgical industry produces steel 38hmj similar in structure and properties.
Composition of steel 34CrAlMo5:
| Element | Carbon | Silicon | Manganese | Chrome | Molybdenum | Aluminum |
|---|---|---|---|---|---|---|
| Percentage content in steel | 0,30…0,37 | Up to 0.40 | 0,40…0,70 | 1,00…1,30 | 0,15…0,20 | 0,80…1,20 |
In the steel 34CrAlMo5 traces of copper and nickel are allowed, the limit of phosphorus is not higher than 0.025%, sulfur — 0.035%.
Company Evek GmbH offers to buy at a bargain price from the manufacturer circles, bars and forgings made of medium-carbon alloy steel grades 38KhMYUA, 34CrAlMo5, 38hmj. The supplier provides proper quality of supply of rolled products and forgings, as well as guarantees the customer timely delivery of the purchased products.
Properties and application
After annealing, 38CrAlMo5, 38hmj steels have the following mechanical properties:
- Tensile strength, MPa — not less than 235;
- Ultimate ductility, MPa — not less than 123;
- Tensile strength, kJ/m2 — not less than 14;
- Relative elongation, % — 14;
- Brinell hardness, HB — not more than 132.
Forgings produced from 38KhMYAA steel meet the requirements of GOST 8479. Steels are used for production of steam turbine rods, valves, gears, shafts and similar parts operated at temperatures up to480−5000 C. Well amenable to nitriding, after which it acquires increased resistance against corrosion.
