Young’s Modulus of 47.8 GPa is equal to 6,933,000 psi. Steel is 30,000 psi.

Steel is 30,000 psi.

Not an engineer, but I know what the head markings on steel bolts mean, and that appears to be some pretty sorry steel you've got there.

Don't know where you got this, but ResearchGate Materials Data Book gives high carbon steel Young's modulus as roughly 1000 GPa and tensile strength as about 1000 MPa.

For your information, Young's modulus is not the yield strength. Engineering is a bit more complex than one mught suppose.

From Wikipedia

Steel (ASTM-A36) 200GPa 29.0×10^6 psi

Need to check units, and not confuse with Yield Strength.

(Trying to remember from 50 years ago.)

Tensile strength is not the same as Young's Modulus, which is a measure of elasticity. For reference, the Young's Modulus, E, for Steel is 200 GPa ≅ 29 x 106 psi.

Sorry... didn't see that others had already pointed out your error... I don't like to "dog pile on the rabbit".
