The aim of this work is to develop a quantitative analysis of requirements of the AISI 304 and AISI 347 materials, and their German equivalents, DIN X5CrNi18-10 and DIN X6CrNiNb18-10, respectively, in order to predict the mechanical behavior. To this purpose, we have carried out prediction studies based on the estimation of ferrite-δ content and its relationship with hot-cracking described in the literature. Additionally, chemical and mechanical requirements have been evaluated by the application of a deterministic algorithm based on Stringency Levels. Results show that steel DIN X6CrNiNb18-10 can be defined as the best option, because of its lowest hot cracking susceptibility and the high stringency of its requirements.
