This is a review based on classic and recent published literature regarding hydrogen diffusion and hydrogen assisted cracking in stainless steels. The majority of the reviewed literature is related to supermartensitic, duplex and super duplex stainless steels. Recent models for hydrogen diffusion and hydrogen assisted fracture in the presence of sharp notches are presented and discussed. New approaches in cohesive FE modelling of hydrogen assisted cracking are presented and reviewed as a possible method for building a bridge between the modelling of micro mechanisms in the fracture process zone and the global fracture response.
