Composition and properties
60C2, 60si7, 60s2 spring steels are produced by hot-rolling methods. According to
| Chemical element | Carbon | Silicon | Manganese | Chrome | Nickel |
|---|---|---|---|---|---|
| Content in steel, % | 0,57...0,65 | 1,50...2,00 | 0,60...0,90 | Up to 0.3 | Up to 0,4 |
In addition to the elements listed in the table, in the composition of steel 60C2 also present sulfur and phosphorus. The total content of these metallurgical impurities should not exceed 0.06%.
The closest foreign equivalents of steel 60C2 are: in the United States and North America - steel 9260H, delivered according to standards AISI, in Europe - steel 60si7 and 60s2, the chemical composition and properties of which meet the standards UNS. The composition of these steels is as follows:
| Steel grade | С | Mn | Si | P | S |
|---|---|---|---|---|---|
| 9260Н | 0,55...0,65 | 0,65...1,05 | 1,70...2,20 | Up to 0.035 | Up to 0.040 |
| 60si7 | 0,57...0,64 | 0,60...0,90 | 1,50...2,00 | Up to 0.040 | Up to 0.040 |
The main physical and mechanical properties:
- Tensile strength, MPa - 1300 (for foreign analogues - up to 1100 MPa);
- Ultimate ductility, 420 MPa (for foreign analogues - up to 390 MPa);
- Relative elongation, % - not more than 25;
- Brinell hardness - not above 285.
Application
The spring steels of all the above mentioned grades are well amenable to heat treatment according to the standard mode: quenching at 8700 C in oil, followed by tempering at 430...4600 C. Bulk rolled materials of these steels at high surface hardness are characterized by high-temperature toughness at the level of 250...300 kJ/m2 that provides materials with good wear resistance under conditions of increased temperatures and time-varying dynamic loads. In this connection from the bars of steel 60C2, 60si7 and 60s2 produce springs and springs of rail vehicles - passenger, freight and streetcar cars and other mechanisms for the operation of which these loads are required. Wire of these steel grades is the starting material for the production of high-strength fasteners.
It is profitable and reasonable to buy volumetric rolled metal products - wire, rounds and bars made of steels 60C2, 60si7 and 60s2 from Evek GmbH. The company provides strict compliance with the range of supply, as well as guarantees the necessary quality of products shipped to the consumer.
