it depends on the mix and application. It varies between 9 and 12GPa (1300 and 1700 ksi)
Young's modulus is stress/strain. So if the modulus is high, it means that the stress value is greater compare to that of the material where the modulus is low. or in other words, the strain is very less compared to that of the material having low Young's modulus. So it tells that, if a material has high Young's modulus, the material requires more load for deformation of shape (within elastic limit).

Young’s Modulus (also referred to as the Elastic Modulus or Tensile Modulus), is a measure of mechanical properties of linear elastic solids like rods, wires, and such. Other numbers measure the elastic properties of a material, like Bulk modulus and shear modulus, but the value of Young’s Modulus is most commonly used. This is because it gives us information about the tensile elasticity of a material (ability to deform along an axis). Young’s modulus describes the relationship between stress (force per unit area) and strain (proportional deformation in an object). The Young’s modulus is named after the British scientist Thomas Young. A solid object deforms when a particular load is applied to it. The body regains its original shape when the pressure is removed if the object is elastic. Many materials are not linear and elastic beyond a small amount of deformation. The constant Young’s modulus applies only to linear elastic substances.
The tangent modulus of steel varies depending on if the steel has yielded.If the steel has not yielded, and is still elastic (stresses less than approx. 275 MPa (39885 Psi) the tangent modulus will be equal to the Young's Modulus, 205 GPa (39885367)If the steel has yielded, the tangent modulus will be related by the Ramsberg-Osgood Equation, but a reasonable value to use would be approx. 1.5 GPa (2175565 Psi)
what is the flexural modulus value od mild steel
The practical use of the elastic constant, such as Young's modulus or shear modulus, is to quantify the stiffness or rigidity of a material. Engineers and designers rely on these values to predict how a material will deform under stress and to ensure that structures or components will perform as intended without failing. This information is crucial for selecting appropriate materials for various applications in construction, manufacturing, and other industries.

Young's modulus describes the relationship between stress (sigma) and strain (epsilon) in a material that obeys Hooke's law. That means that there is a linear elastic relationship between stress and strain (which means that for a given change in strain, there will be a linearly proportional change in internal stress). Young's modulus (E) is calculated as follows: E = sigma / epsilon Where: epsilon (strain) = change in length of sample / original length [-] sigma (stress) = force / area [N/m-2]
The Elastic Modulus (aka Young's Modulus) for annealed 304 stainless steel is 193 GPa. More data is available at: http://www.azom.com/details.asp?ArticleID=965
applications of modulas of elasticity As the term implies, "Modulus of Elasticity" basically relates to the elasticity or "flexibility" of a material. The value of modulus of elasticity are very much significant relating to deflection of certain materials used in the construction industry. Take for example the general E value of mild carbon steel is about 200 GPa compared to about 70 GPa for aluminum. This simply translate that aluminum is 3 times flexible than steel.
Polyester does
No, it will not change. Young's modulus is a property of the material and not dependent on dimensions. Rigidity, or product of modulus and inertia, will change, as inertia depends on dimensions; but modulus does not change.
