Several known methods of controlling the entry and exit of hydrogen in steel were correlated with the known chemical behavior of atomic and molecular hydrogen. Through this correlation, suitable reagents were found which increase or, for the first time, significantly decrease hydrogen permeability and embrittlement of SAE 4130 and other steels during cathodic pickling and of spring steel during zinc and cadmium plating without lessening the apparent quality of the pickling or the plating.
