CORROSION FATIGUE BEHAVIOR OF 13 CR STAINLESS STEEL FOR TURBINE MOVING BLADE

Failure of the blades of marine and compressor driving turbines -- due to corrosion fatigue -- has often been reported in recent times. However, little information is available on the corrosion fatigue of 13 Cr stainless steel used for the moving blades of turbines. This paper presents the results of rotating bending fatigue tests on 13 Cr stainless steel in NaCl and NaOH aqueous solutions of various concentrations, and observation results of corrosion pits, subcracks and fracture surface of the specimen in the cited environments. The concentration of Cl at the bottom of the corrosion pit is found to be one of the factors which govern the corrosion fatigue behavior of 13 Cr stainless steel in environments containing C1.
