High-carbon hot-rolled spring steel 60C2, 60si7 and 60s2 belong to low-alloy structural steels. According to
| Component | C | Si | Мn | Cr | Ni |
|---|---|---|---|---|---|
| Content in steel, % | 0,57...0,65 | 1,50...2,00 | 0,60...0,90 | Not more than 0.3 | Not above 0.4 |
Also in the composition of steel 60C2 present sulfur and phosphorus, which are metallurgical impurities. GOST stipulates that the total percentage content of these chemical elements can not be more than 0.06%.
Steel grade 60C2 has a number of foreign counterparts. The closest analogue in the US is steel 9260H, which is produced according to AISI standards. The European counterparts of 60C2 steel are 60si7 and 60s2, which are produced in accordance with European standards UNS and DIN. The chemical composition of these steels is somewhat different from that of 60C2, as shown in the table below:
| Material Designation | 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 of steel after rolling are:
- ultimate strength, MPa - 1300 (for foreign analogues - up to 1100 ... 1200 MPa);
- ultimate ductility, MPa - 420 (for foreign analogues - up to 400 MPa);
- Relative elongation - not more than 25%;
- Brinell hardness - not more than 285 HV.
Application
All the above mentioned spring steels after rolling are subjected to heat treatment - quenching at the temperature of 8700 C in oil, with the following tempering, which is performed at the temperature of 430...4600 C. The indicators of wear resistance and impact toughness of steel are maintained up to the operation temperatures of 150...1800 С. This makes it possible to use initial sheet rolled steel - strips, bands, (as well as thick plates after hot forging) in the manufacture of flat springs of shoe and disk brakes of various equipment - industrial and transport. From the strips and strips of steel 60C2, 60si7 and 60s2 also made springs of critical application.
Buy sheet metal products - strips and bands made of steel grades 60C2, 60si7 and 60s2 on the proposal of Evek GmbH is economically viable. The company guarantees the necessary range of products supplied in thickness and overall dimensions in the plan. All rolled product lots are provided with quality certificates from the manufacturer.
