Speaker: Tom Lienert, B.S. in Welding Engineering, M.S. and Ph.D. in Materials Science and Engineering
Overview: Stainless steels, defined as steels containing more than 10.5% Cr, find broad use in industry owing to their corrosion resistance in many environments. This presentation will discuss how stainless steels form a protective surface oxide layer to resist corrosion. It will also provide insight into how stainless steels undergo sensitization within a specific temperature range allowing intergranular corrosion along grain boundaries. Implications on intergranular corrosion in the HAZ of welded stainless steels will be discussed, and methods for minimizing intergranular corrosion will be presented.
