There is a large body of publications regarding uses of cast iron. But very few of them are concerned with the use of cast iron in refrigeration equipment, and even less with the behavior of such materials at low temperatures.

Some studies concerning the use of cast iron items at low temperature were made in the military field, but these studies were generally not accessible to the public, since they were considered secret information.
The purpose of this three-part series is to attempt to provide answers to several questions that may arise during the process of designing cast iron items for industrial refrigeration equipment:
