Which of the following areas is/are corroded in the intergranular corrosion of stainless steel? Correct Answer Chromium depleted zone near the grain boundary

!8-8 stainless steel is susceptible to intergranular corrosion due to sensitization in the temperature of 950 to 1450°F. At this stage, chromium reacts with carbon near the grain boundary and results in the formation of the chromium depleted zone. This chromium depleted zone is prone to intergranular corrosion.
