During the serves cycle, leaf spring must not exceed certain level of stress to avoid settling or premature failure. Therefore, the choice of chemical composition of the spring steel should be such to get sufficient harness to bear the required level of stress. Spring steel flats are available in various chemical compositions of alloy steel.
Types
- Carbon Spring steel
- Silicon Manganese Spring steel
- Chromium Vanadium Spring steel
Details of grades and there chemical composition can bS provided on request.
