about 70 to 80 GPa
it is 14.67n/m3
modulus of elasticity = 15 Msi; poisson ratio = 0.3 modulus of rigidity = E/ ((2(1 + poisson)) = 5.8 Msi
The modulus of elasticity of spring steel is typically around 30 million pounds per square inch (psi).
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
The rigidity modulus, also known as the shear modulus, is a material property that measures its response to shear stress. It is independent of the dimensions of the wire, such as its radius. Therefore, if the radius of the wire is doubled, the rigidity modulus remains unchanged. The deformation behavior of the wire may change due to the increased cross-sectional area, but the rigidity modulus itself is a constant for that material.
G = E/2(1+u) where G = mod of rigidity and u =poisson ration and E = young modulus

The modulus of rigidity of a wire is a measure of its resistance to shearing deformation. It is typically represented by the symbol G and is expressed in units of pascals (Pa). The specific value of the modulus of rigidity for a given wire will depend on its material composition and properties.
The modulus of elasticity of spring steel is typically around 30 million psi. This property determines how much a material can deform under stress and return to its original shape. A higher modulus of elasticity in spring steel means that the material can withstand greater stress without permanent deformation, resulting in more durable and efficient springs.
The shear modulus, also known as the modulus of rigidity, for C1018 steel is typically around 79 GPa (gigapascals) or approximately 11.5 million psi. This value can vary slightly depending on the specific heat treatment and processing of the steel. C1018 is a low-carbon steel commonly used in various engineering applications due to its good machinability and weldability.
It is around 40 GPa.
About 29-30 million psi, depending on type of steel, but close enough for most steels.
