Abstract
Solution nitriding was applied to type 304 stainless steel plate to make the austenite phase in the surface layer stable against cold rolling. Through this treatment, we could produce a structure-gradient stainless steel plate where an austenitic structure exists in the surface layer while a large fraction of deformation-induced martensitic structure is dispersed inside the plate. This surface-layer microstructure control significantly suppressed the permeation of hydrogen from the atomosphere owing to the low diffusivity of hydrogen in the stable austenitic surface layer.
