Question

Which of the following is/are the applications of Duriron because of its corrosion resistance and inherent hardness?

(a) To manufacture pumps, valves, and fans

(b) To make heat exchangers

(c) Impressed–current anodes

(d) To manufacture pumps, valves, fans, heat exchangers and impressed-current anodes

This question was posed to me in unit test.

Question is from Mineral Acids topic in section Mineral Acids of Corrosion Engineering

Answer 1

Correct answer is (d) To manufacture pumps, valves, fans, heat exchangers and impressed-current anodes

The best I can explain: Duriron is high-silicon cast iron with high corrosion resistance and inherent hardness. It is used to manufacture pumps, valves, fans, heat exchangers, and impressed-current anodes.
