Ferritic stainless steel (FSS) is most commonly used in automotive exhaust systems because of their good combination of thermal fatigue resistance, high temperature strength, corrosion resistance and low cost. In the presented study, the intergranular corrosion resistance and the condensate corrosion resistance of 0Cr11NbTi stainless steel were tested and compared to those of 0Cr11Ti , which is conventionally used abroad so as to provide references for the selection of materials and the design of parts in automotive exhaust Systems. This study investigates the corrosion properties of 0Cr11Ti and 0Cr11NbTi ferritic stainless steels (FSS) for automotive exhaust Systems. The results indicate that the base metal and weld seam of 0Cr11NbTi steel exhibit better intergranular and condensate corrosion resistant properties because carbon and nitrogen are stabilized by Nb and Ti , and the precipitation of Cr carbide is retarded in grain boundaries.
