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.展开更多
文摘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.
