What is the Young's Modulus of Steel?
The Young’s modulus of steel (also referred to as modulus of elasticity of steel) is between 190 – 210 GPa at room temperature, which is around 27500 ksi to 31200 ksi. The steel young modulus is a measure of its stiffness/ resistance elastic deformation to tensile loads.
The reason for differing values of young’s modulus of steels is due to the manufacture process, which accounts for the amount of impurities in the steel and the type/grade of steel specified.
The unit of of Young’s Modulus is usually taken as Gigapascal (GPa) which isĀ Pascals x 109
The European standard states the young’s modulus of steel as 210,000 MPa in accordance to EN 1993-1-1 Section 3.2.6.

How do we find the Modulus of elasticity of steel?
The steel elastic modulus is determined from experimental data of a tensile test on a material specimen. The tensile test applies a tensile stress, and the deformation (strain) is measured at each instance the load increases.
A stress strain curve is plotted graphically, and the steel elastic modulus is the slope of the linear elastic part of the curve. Through Hooke’s law, we can define the Young’s modulus of steel to be \(E = \sigma / \varepsilon\).
The equation above has been rearranged from this formula: \(\sigma = E. \varepsilon\).
