1.	Which of the following is/are the stabilizing elements to minimize intergranular corrosion of stainless steel?(a) Niobium(b) Columbium(c) Titanium(d) Niobium, columbium, and titaniumThe question was posed to me in a national level competition.I'd like to ask this question from Eight Forms in chapter Eight Forms of Corrosion of Corrosion Engineering
Answer» Correct choice is (d) NIOBIUM, columbium, and titanium The BEST I can explain: Stabilizing ELEMENTS are the elements that form strong carbides than chromium. These elements have a much greater AFFINITY to carbon than does chromium, this minimizes the chromium depleted zone.
