Composition and properties
In the CIS medium-alloy structural steel 30CrM is produced according to GOST 4543 norms and has the following chemical composition:
| Element | Carbon | Silicon | Manganese | Chrome | Molybdenum |
|---|---|---|---|---|---|
| Percentage content | 0,26…0,34 | 0,17…0,37 | 0,40…0,70 | 0,80…1,10 | 0,15…0,25 |
GOST allows the presence of metallurgical impurities — phosphorus and sulfur, which quantity should not exceed 0,025…0,030%.
The closest foreign analogues of this material are steel 25CrMo4 and 1.7218. They insignificantly differ from 30CrMo grade by chemical composition:
| Element | Carbon | Silicon | Manganese | Chrome | Molybdenum |
|---|---|---|---|---|---|
| Percentage content | 0,22…0,29 | Up to 0.40 | 0,60…0,90 | 0,90…1,20 | 0,15…0,30 |
In addition, European standards allow for the presence of copper (up to 0.3%), nickel (up to 0.4%), and aluminum (up to 0.04%) in the above steels.
The mechanical properties of the steels in question after annealing are as follows:
- Ultimate strength, MPa — 950;
- Ultimate ductility, MPa — 750;
- Relative elongation, % — 11;
- Relative narrowing, % — 50;
- Tensile strength, kJ/m2 — 900.
Company Evek GmbH offers to buy a circle, bar, tube of steel 30XM, 25CrMo4 and 1.7218. The price is from the manufacturer. Supplier guarantees product delivery to any location specified by the customer.
Application
These steels are well amenable to all kinds of heat treatment, as well as plastic forming with significant degrees of deformation. Therefore they can be used for manufacturing quite complex three-dimensional parts such as shafts, flanges, medium-sized gears and pinions. Steels have good weldability, so tubular products made of the described materials are used for laying main pipelines.
