Permeation of H in Steel

$$ P = P_0 \exp\left(-\frac{E_\mathrm{p}}{k_\mathrm{B}T}\right) $$

[In the above formula, the Boltzmann constant is expressed in $\mathrm{eV\,K^{-1}}$.]

Material: Steel
Method: Experiment
Data scaled for isotope mass? No

P₀ = 2.598e-07 mol m^-1 s^-1 Pa^-1/2
E_p = 0.7 eV
T = 293 – 1253 K
