leaf spring material and young's modulus values

[mach11]

Hey guys,

i was searching the net and was unable to obtain
1. what materials are commonly used for making leaf springs... is it steel or any other thing????

2. Also if at all any other material is used can i get the young's modulus values of that....

Thanks in advance

Hi guys....

i got the material codes for the material used in leafsprings....
1. 55Si2Mn90
2. 50Cr1
3. 50Cr1V23

Is there any pdf versions of all the youngs modulus values of metals, alloys etc.

thanks

Corvettes have composite springs till the 90s ...and ZF boasted around they´d start manufacturing composite lefsprings in the years to come..

Use a general Young's modulus of steel. 200 kN/mm2.
You will have a good approximation. The different alloys do not have huge variations (195-210 kN/mm2). The variation is more in other mechanical properties. As a rule of thumb the modulus will go up with higher melt temperature of the alloy.
