A high-strength 316L stainless steel with heterostructure (HS) was used to explore its corrosion properties in 3.5wt.% NaCl solution at 25 °C. Compared with a conventional coarse-grained (CG) sample, the HS sample with the characteristic of that the recrystallized grains (RGs) were surrounded by ultrafine/nano-structures (UFS/NSs) exhibited an enhanced pitting resistance. This was ascribed to interrupted propagation of the stable corrosion pits in RGs by the surrounded UFS/NSs. The results in current work may provide a new strategy to improve corrosion properties by heterostructural designing.
