An overview is given of hydrogen diffusivity in a number of corrosion resistant alloys. Methods of measurement and their analytical framework, which underpin the quality and significance of the data, are described initially. Diffusion data are then presented for martensitic stainless steels, duplex stainless steels and nickel-base alloys and discussed in the context of the microstructural characteristics of the material.
