Solid solution nitriding (SSN) treatment at 1200℃ was applied to type 304, and the effect of sensitization on fatigue behavior was studied. Furnace-cooled and water-quenched specimens were used for fatigue tests in 3%NaCl condition. In addition, thrnace-cooled specimen was re-solution treated to dissolve CrN. The fatigue strengths of SSN specimens were lower that of untreated one due to sensitization, while water quenching could reduce the effect of sensitization.
