Pitting Behavior of Sensitized 444 Stainless Steel in Hot Tap Water

More Information
  • Received Date: March 14, 2020
  • The corrosion behavior of sensitized 444 stainless steel in 80 ℃ tap water was studied by electrochemical method. The results showed that in hot tap water, the polarization resistance of the sample decreased with the increase of the sensitization degree, and the surface passivation ability decreased. The pitting resistance and sensitization degree had similar evolution characteristics with the aging time. The higher the sensitization degree, the worse the pitting resistance performance of the sample. Pitting will occur preferentially at the grain boundaries of the sensitized sample.
