Can anyone help me I need the material Properties for this material Youngs Modulous
Possions Ratio
Mass Density
Thermal Coefficient
 
Young's Modulus for steel is mostly invariant to chemical composition, processing, etc. The value is around 207 GPa. Poisson's ratio is usually accepted to be 0.29. Mass density is ~ 7.85 g/cm3. Thermal expansion coefficient is ~ 12 x 10-6m/mK from 20-100 C. From 20-200 it is ~ 12.5, 20-300 it is ~ 13.0, and 20-400 it is ~ 13.6.
 
I assume you are referring to ASTM A 611. If so, you can use the properties of SAE 1020:

Young's modulus E = 205 GPa
Poisson's ratio &[ignore]nu[/ignore]; = 0.29
Mass density &[ignore]rho[/ignore]; = 7.87 &[ignore]middot[/ignore]; 103 kg m-3

I assume your "Thermal Coefficient" is the Linear Thermal Expansion Coefficient. If so, then use &[ignore]alpha[/ignore]; = 11.7 &[ignore]middot[/ignore]; 10-6 K-1
