...-rolled bars, it is common practice to specify a torsional modulus of 72 GPa (10 × 10 6 psi) instead of the 80 GPa (11.5 × 10 6 psi) used for small spring wires. In part, this compensates for the low strength of the surface layer. Total loss of carbon from the surface during a hear-treating process...
