Composition and properties
Spring steel 60S2, 60si7, 60s2 produced by the methods of hot rolling. According to Russian GOST 14959 steel 60S2 has the following chemical composition:
| Chemical element | Carbon | Silicon | Manganese | Chrome | Nickel |
|---|---|---|---|---|---|
| The content in steel, % | 0,57 0,65… | 1,50 2,00… | 0,60…0,90 | To 0.3 | To 0.4 |
In addition to the items listed in the table in the steel 60S2 there are also sulphur and phosphorus. The total content of these metals impurities should not exceed 0,06%.
The closest foreign analogues of steel 60S2 are: in the United States and North America — steel 9260Н supplied according to standards of AISI, in Europe — have 60si7 and 60s2, chemical composition and properties of which meet the standards UNS. The composition of these steels is equivalent to this:
| Steel grade | With | Mn | Si | P | S |
|---|---|---|---|---|---|
| 9260Н | 0,55…0,65 | 0,65 1,05… | 1,70 2,20… | To 0.035 | To 0.040 |
| 60si7 | 0,57 0,64… | 0,60…0,90 | 1,50 2,00… | To 0.040 | To 0.040 |
The main physico-mechanical characteristics:
- The limit of temporary resistance, MPa — 1300 (that of their foreign counterparts — up to 1100 MPa);
- The plastic limit, MPa — 420 (from foreign counterparts to 390 MPa);
- Elongation, % not more than 25;
- Brinell hardness number is no higher than 285.
Application
Spring steel for all the above mentioned brands lend themselves well to thermal treatment according to standard modes: quenching from 8700 C in oil, with following tempering at 430…4600 C. the Bulk metal of these steels when high surface hardness is different high temperature viscosity at 250…300 kJ/m2, which gives the materials good wear resistance in conditions of high temperatures and time-varying dynamic loads. In this regard, from bars of steel 60S2, 60si7 and 60s2 produce springs and leaf springs of railway vehicles — passenger, freight and tram-cars and other mechanisms for the operation which requires the specified load. Wire data of grades of steel — the raw material for the production of high-resistance fasteners.
Buy bulk metal — wire, round, rod of steel 60S2, 60si7 and 60s2 of the company Electrocentury-steel is beneficial and appropriate. The company ensures strict compliance of the assortment of supply and also guarantees the required quality of shipped consumer products.
