The Young Modulus of Spheroidal Cast Iron is aproximately 170000 N/mm2 [MPa] - 24500000 psi. Of course it depends on the grade of the cast iron. It can vary a lot if oyu will consider also the family of malleable cast iron where the range of values is from 60000 to 170000 N/mm2 - from 10000000 to 24500000 psi.
Engineering Fundamentals lists the elastic modulus of 4140 as 190-210 gigapascals (30 million PSI). Wikipedia agrees with this range. Curiously, annealing, cold-working, or hardening the steel doesn't affect its elastic modulus much, although the tensile strength is greatly affected.

The Young modulus and storage modulus measure two different things and use different formulas. A storage modulus measures the stored energy in a vibrating elastic material. The Young modulus measures the stress to in still elastic, and it is an elastic modulus.
The young modulus young modulus(E) = stress/strain stress = force/area strain = extension(total length)/original length It is this property that determines how much a bar will sag under its own weight or under a loading when used as a beam within its limit of proportionality
physics coursework??
From 110 - 130 Gpa

young modulus remain unaffected ...as it depends on change in length ..
I think you mean "What variables affect young's modulus". Obviously not an english major!
Young's modulus-205 kN/mm2 Poisson's ratio = 0.30
there are different types of modulus it depends on what types of stress is acting on the material if its direct stress then then there is modulus of elasticity,if tis shear stress then its modulus of rigidity and when its volumetric stress it is bulk modulus and so on
Metal is not a specific material, how is this ever going to be answered?!
Depends on the hardness of the formulation. Poisson's ratio depends mainly on the bulk modulus and slightly on the Youngs modulus at very low strains for the subject compound. If the Youngs modulus lies between 0.92 and 9.40MN/m², Poisson's ratio lies between 0.49930 and 0.49993.
G = E/2(1+u) where G = mod of rigidity and u =poisson ration and E = young modulus
The value for the cleavage plane (100) is 38 GPa and the value for the cleavage plane (001) is 33 GPa.
This is known as the Modulus of Elastisity, or Youngs Modulus (in tension/compression) and will be a constant as long as the deformation is in the elastic range.
