Comparison of corrosion in STS304 and STS316 according to electrical stimulation intensity, frequency, and time. The sections shaded gray indicate corrosion (), and the section in white indicates no corrosion (X). No corrosion was observed in STS304 under any conditions with an intensity less than 3 and a duration less than 10 min, and no corrosion was observed in STS316 under any conditions with an intensity below 4 and a duration less than 15 min (except 60 Hz for 15 min). Based on the results above, STS316 is more resistant than STS304 to corrosion after the application of electrical pulses
