        Absorption of H₂ by liquid Fe, by Fe products during heat treatment in H₂-containing atmospheres, and by Fe during pickling is explained.  Dissolved and absorbed H₂ are partly lost during hot and cold working or by exposure of metal to the atmosphere.  H₂ causes decarburization in Fe-C alloys and decreased watt loss in transformer steel sheets.  X-ray examination shows H₂ is dissolved in the a- and γ-lattices, produces an increase in lattice constant, and acts especially on the intercrystalline material.
