Abstract:TCS stainless steel is a cheap ferritic stainless steel due to low Cr (12%Cr) and Ni(≤2.0%Ni) content. The mechanical properties of HAZ are critical to the applications. The structure evolution and heat cycle characteristics of HAZ were examined and, based on the experimental data, the mechanical properties of HAZ were investigated by using Thermal Mechanical Simulator Gleeble 1500. The results show that in HAZ, the ferritic phase was transformed into the ferritic and the martensitic phase, and both strength and yield ratio were increased. Compared with the parent steel, the ductility sharply decreased in the coarse grain zone of HAZ.
