Hot rolled high carbon spring steel 60S2, 60si7 and 60s2 belong to low alloy structural steels. In accordance with GOST 14959 steel 60S2 domestic production has such chemical composition:
|The content in steel, %||0,57 0,65…||1,50 2,00…||0,60…0,90||Does not exceed 0.3||Not greater than 0.4|
Also, the composition of the steel 60S2 are sulfur and phosphorus, which are metallurgical impurities. GOST stipulates that the total percentage content of these chemical elements may not be more than 0.06%.
Steel 60S2 brand has a number of foreign counterparts. In the US the closest analog is the steel 9260Н, the production of which is conducted according to the AISI norms. European equivalents of steel 60S2 — 60si7 and steel 60s2, which are produced in accordance with European standards DIN and UNS. The chemical composition of these steels is somewhat different from the steel 60S2, which follows from the table:
|The material designation||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 of the steel after rolling are:
- Tensile strength, MPa — 1300 (for foreign counterparts — up to 1100…1200 MPa);
- The plastic limit, MPa — 420 (for foreign counterparts — up to 400 MPa);
- Elongation is not more than 25%;
- Brinell hardness number — no more than 285 HB.
All of the above spring steel after rolling is subjected to heat treatment — hardening at a temperature of 8700 C in oil, with further leave, which is produced at a temperature of 430…4600 C. the wear resistance and toughness of steel to maintain operating temperature 150…1800 C. This gives the possibility to use the original sheet metal — tape strip, (as well as the plate of the plate after hot forging) in the manufacture of flat springs drum and disc brakes of various equipment, production and transport. From strip steels 60S2, 60si7 and 60s2 are also manufactured springs for critical applications. .
Buy metal sheet — tape and band made of steel 60S2 brands, 60si7 and 60s2 on the proposal of the company Electrocentury-steel economically feasible. The company guaranteed the necessary range of products supplied by the thickness and overall dimensions in plan. All party rentals are supplied with quality certificates from the manufacturer.
