A bstract The experimental evidence gathered during the investigation of seven ferrous metals shows that there is a relationship between the hydrogen behavior and enameling characteristics of these metals. This relationship can best be explained on the basis of diffusibility of atomic hydrogen through these metals and is in no way affected by the total carbon content or by the stabilization of the carbon through the formation of carbides other than iron carbide. These added metallic elements may decrease the diffusibility of hydrogen through steel in two ways, namely, (1) they may have a poisoning or reverse catalytic effect on hydrogen diffusion or (2) they may “plug the gaps” in the crystal lattice and by so doing render the metal impenetrable to atomic hydrogen diffusion.
