Chemical Properties
Structural alloyed steel of grade 20XM with high content of molybdenum and chromium is produced by metallurgical plants of CIS countries according to technical requirements of GOST 4543. The steel has the following composition:
| Element | Carbon | Silicon | Manganese | Chrome | Molybdenum |
|---|---|---|---|---|---|
| Content in steel, % | 0,15…0,25 | 0,17…0,37 | 0,40…0,70 | 0,80…1,10 | 0,15…0,25 |
The maximum content of metallurgical impurities — sulfur and phosphorus — is limited by 0,025% for each of the elements.
Foreign counterparts of this steel are grades 24CrMo5 (1.7258), which are produced in Europe according to the requirements of EN 10028−2 and DIN 17755.
In Poland similar steel is produced under the brand 20 hm, and its composition does not differ from 20CrMo5. The chemical composition of 24CrMo5 and 1.7258 is given below:
| Element | Carbon | Silicon | Carbon, silicon | Chrome | Molybdenum | Nickel |
|---|---|---|---|---|---|---|
| Content in steel, % | 0,20…0,28 | Up to 0.40 | 0,50…0,80 | 0,90…1,20 | 0,20…0,35 | Up to 0.60 |
Quantitative limitation for impurities — phosphorus and sulfur — is up to 0,035%.
Company Evek GmbH offers to buy pipes, rounds, bars of alloyed structural steel of 20XM, 24CrMo5, 1.7258, 20 hm grades at the price from the manufacturer. The supplier ensures fulfillment of the product range and prompt transport of rolled products to the address specified by the customer.
Properties and application
The steel under consideration is characterized by a high percentage of chromium and molybdenum, which predetermines the increased performance of heat resistance of parts made of these steels. The steels are characterized by high ductility (ultimate strain rate is 85%), are well machined by cutting, capable of effective heat treatment under various regimes. The steels are used in aircraft and transport engineering, in the manufacture of mechanical transmission parts, etc.
