Abstract Permeability, diffusivity and solubility of hydrogen in austenitic stain-less steels 316L, 316LN, 21-6-9, 21-9-9, 304 and 1Cr18Ni9Ti have been measuredby gaseous permeation technique over the temperature range of 200 to 430℃. Theeffects of composition, cold-work and heat treatment on hydrogen petmeation havebeen investigated. The results indicate that permeability and diffusivity of hydro-gen in various alloys over the experimental temperature range follow arrheniusequations and hydrogen permeation behaviour is not obviously influenced by cold-work and heat treatment of materials, but slightly influenced by the composition.The difference of hydrogen permeation behaviour between pure iron, low alloysteels and austenitic stainless steels has also been discussed.
